Bird Introduction-American Goldfinch

🐦Bird Introduction-American Goldfinch:
This handsome little finch is the state bird of New Jersey, Iowa, and Washington. They are welcomed and common at Birdfy, where it takes primarily sunflower and nyjer.
Spring males are brilliant yellow and shiny black with a bit of white. Females and all winter birds are more dull but identifiable by their conical bills; pointed, notched tails. During molts, they look bizarrely patchy.
📝Basic Info:
Scientific Name: Spinus tristis
Lifespan: 3-6 years(average)
Size: 4.3–5.5 inches
Weight: 0.39–0.71 ounces (11–20 grams)
Wingspan: 7.5–8.7 inches
🌎American Goldfinch Distribution and Habitat:
The American goldfinch is a short-distance migrant, moving south in response to colder weather and lessened food supply. This responsive, southerly migratory pattern is thought to begin to occur as daily low temperatures approach freezing, particularly as these temperatures near 0 °F. Its winter range includes southern Canada and stretches south through the United States to parts of Mexico.
The goldfinch’s main natural habitats are weedy fields and floodplains, where plants such as thistles and asters are common. They’re also found in cultivated areas, roadsides, orchards, and backyards. American Goldfinches can be found at feeders any time of year, but most abundantly during winter.
🌳American Goldfinch in the backyard:
Remember to check birdseed for spoilage. The seed should be fresh and dry to cater to goldfinches' tastes, so use baffles to keep it dry and opt for feeders where air can circulate around the seed to keep it from molding. Clean up hulls and spill seed underneath bird feeders. This will minimize the risk of spreading diseases to finches foraging on the ground or to other ground-feeding birds such as sparrows and doves.
🪺American Goldfinch Breeding:
Once a male has found a mate, he selects a territory, marking the boundaries by warbling as he flies from perch to perch.
The nest is built in late summer by the female in the branches of a deciduous shrub or tree at a height of up to 10 m (33 ft). The nest-building lasts approximately six days, during which time the female works in 10–40 minute increments. The male frequently flies with the female as she collects nesting materials, and though he may carry some materials back to the nest, he leaves its construction to the female.
🌟American Goldfinch and its similar species:
Lesser Goldfinch-Small finch with a conical bill. Adult males are yellow below with a glossy black cap and white patches on the wings. Their backs can be solid glossy black or dull green, particularly west of the Rockies.

Interspecific Allopreening

Every time when I go out for birding, I’m always interested in seeing birds that I haven’t seen previously, or “lifers” in birding terminology. However, there is something that fascinates me even more: behaviors. Birds display all kinds of behaviors related to foraging, mating, antipredation, and more… Many of these behaviors vary temporally and spatially. For example, some migratory birds that forage high up in the canopy during the breeding season shift to understory foraging on their wintering grounds. Additionally, behaviors can vary in different social contexts, which include the presence/absence of their social partners. Today, let’s chat about one rare and understudied bird behavior, interspecific allopreening.


In Latin, the root allo- means other. As preening refers to the movement when one bird tidies its feathers with its bill, and allopreening refers to the behavior when one bird uses its bill to tidy the feathers of another bird. I’m sure some of you have seen this behavior between different individuals of the same species (within-species allopreening). For example, perhaps you have seen a pair of Mourning Doves preen each other after a courtship display? Or maybe you have seen your pet parrots preen on each other? While within-species allopreening is common, interspecific allopreening is much rarer.


In natural environments, there are few documented records. First and most notably, interspecific allopreening has been reported multiple times at multiple locations in the New World between Black Vultures and Crested Caracaras. Also in the New World, interspecific allopreening has been recorded between Razorbills and Common Murres in Canada. In the Old World, this behavior has been observed between a Royal Spoonbill and an Australia White Ibis in Australia, a Sacred Ibis and an African Spoonbill in Africa, and two Parakeets in Europe.
Apart from these records, some species in the Blackbird family, such as the Brown-headed Cowbird, are known to actively seek interspecific allopreening from other species by performing allopreening invitation displays. They oftentimes approach other species and gradually lower their heads (head-down display) to allow other species to preen their head and neck areas.


Unfortunately, we don’t really have an answer. Because events of interspecific allopreening are rare, few researchers so far have been able to collect enough data to effectively demonstrate the reasons behind this behavior. Most studies related to interspecific allopreening are based on anecdotes.
📄If you want to learn more about interspecific allopreening behavior, check out this short article that has recently been published in the journal Ecology and Evolution. The authors observed this behavior between two babbler species in Asia and proposed several hypotheses. They also suggested locations and species in which interspecific allopreening is more likely to be observed.

🧐Why do birds form mixed-species flocks❓❓

🧐Why do birds form mixed-species flocks❓❓

If so, you have found yourself a mixed-species flock. 🐦🦅🦉🦜🕊
This flocking behavior among different species occurs all over the world and is most prevalent in the non-breeding season. If you live in the southeastern US, you have probably seen flocks that consist of Tufted Titmice, Carolina Chickadees, Blue-gray Gnatcatchers, Yellow-rumped Warblers, White-eye Vireos, and Downy Woodpeckers. If you observe the flock carefully, you may also find some Black-and-white Warblers foraging along tree trunks in search of hidden insects and other arthropods. Additionally, you may find a hovering Ruby-crowned Kinglet whose flamboyant crown feathers are only visible when the bird is agitated.

To answer this seemingly simple question, researchers have conducted observational, experimental, and theoretical studies for a long time. It seems that most mechanisms that can explain this behavior come down to two benefits associated with mixed species flocking: foraging enhancement and antipredation. On the one hand, flock participants can learn from each other about the locations of food resources. On the other hand, foraging in a large group can lower your own risk of being attacked by predators, not only because you are less likely to be singled out but also because more eyes are watching out for predators (“many-eyes effect”). The foraging and antipredation benefits are not mutually exclusive to each other, as less time spent scanning for predators usually translates to more time spent foraging.

☝️☝️Now, one question might come to your mind: it seems that birds can achieve both foraging and antipredation benefits by flocking with their own species. Then why bother flocking with different species? Here are a few answers. First, different species differ in their foraging niche (foraging microhabitats, foraging maneuvers, and prey items). By foraging with a different species, you avoid competing with your own species that have the same foraging niche. Second, birds can gain foraging and antipredation benefits in ways unique to mixed-species flocks. For example, sallying species, which normally catch prey on the wing, can take advantage of the foraging maneuver of gleaning species, which normally pick prey from leaves or branches. When gleaning species travel through dense foliage, their movement scares up lots of prey items, which then become food for the sallying species that are in the same flock. Also, certain mixed-species flock participants are alarm-callers that are especially good at spotting predators and alarming other flock members. By closely associating with these alarm callers, other birds can reduce the risk of being predated.

🌳🌳Do mixed-species flocks sound interesting to you? As most birds wrap up their breeding season this year, be sure to take a walk in the woods and observe some flocks. How many species do you see in one flock? How many individuals do you count in each species? Which species do you think is the leader of the flock? I hope you have a fun time observing mixed-species flocks.

Bird Introduction-Tufted Titmouse

🐦Bird Introduction-Tufted Titmouse:
The tufted titmouse is a small songbird from North America, a species in the tit and chickadee family. The black-crested titmouse, found from central and southern Texas southward, was included as a subspecies. The large black eyes, small, round bill, and brushy crest give these birds a quiet but eager expression that matches the way they flit through canopies, hang from twig ends, and drop into bird feeders. When a titmouse finds a large seed, you’ll see it carry the seed to a perch.
📝Basic Info:
Scientific Name: Baeolophus bicolor
Lifespan: 2.1 years(average)
Size: 5.5–6.3 inches
Weight: 0.6–0.9 ounces (17–26 grams)
Wingspan: 7.9–10.2 inches
🌎Tufted Titmouse Distribution and Habitat:
The Tufted titmouse is non-migratory and originally native to the Ohio and Mississippi River basins factors such as bird feeders have caused these birds to occupy a larger amount of territory across the United States and stretch into Ontario and Quebec in Canada.
Tufted Titmice will be found in most eastern woodlands below 2,000 feet elevation, including deciduous and evergreen forests. Tufted Titmice are also common visitors at feeders and can be found in backyards, parks, and orchards.
🌳Tufted Titmouse in the backyard:
Tufted Titmouse is regular at backyard bird feeders, especially in winter. They prefer sunflower seeds but will eat suet, peanuts, and other seeds as well.
Tufted Titmouse builds their nests in cavities, so putting up nest boxes is a good way to attract breeding titmice to your yard. Make sure you put it up well before breeding season.
🪺Tufted Titmouse Breeding:
Tufted titmice nest in a hole in a tree, either a natural cavity, a human-made nest box, or sometimes an old woodpecker nest. Eggs measure under 1 inch (2.5 centimeters) long and are white or cream-colored with brownish or purplish spots. On average, these birds will have a clutch size of five to seven eggs. Unlike many birds, the offspring of tufted titmice will often stay with their parents during the winter, and even after the first year of their life.
🌟Tufted Titmouse and its similar species:
A jaunty gray songbird with a bold black crest, the Black-crested Titmouse occurs between two closely related species, the more muted Tufted Titmouse to the east and the even flashier Bridled Titmouse farther west. They are most at home in oak woodlands.
A Bridled Titmouse with black and white on its face, the Bridled Titmouse is a specialty of the middle-elevation forests of the southwestern U.S. and adjacent Mexico. They forage nimbly, often in oak trees, sometimes hanging upside-down from the slenderest of branches.

Bird Introduction-Black-capped Chickadee

🐦Bird Introduction-Black-capped Chickadee:
The black-capped chickadee is a small, non-migratory, North American songbird that lives in deciduous and mixed forests. The black-capped chickadee has a black cap and "bib" with white sides to the face. Its underparts are white with rusty brown on the flanks. Its back is gray and the tail is normally slate gray.
📝Basic Info:
Scientific Name: Poecile atricapillus
Common Name: Black-capped Chickadee, Chickadee
Lifespan: less than 2-3 years
Size: 4.7–5.9 inches
Weight: a half-ounce (12 grams)
Wingspan: 6.3–8.3 inches
🌎Black-capped Chickadee Distribution and Habitat:
They are found year-round from New England to the West Coast. In the West, their range extends as far south as New Mexico. In the east, they follow the Appalachian Mountains south to Georgia. Canadian residents and Alaskans can observe black-capped chickadees near their homes as well.
Chickadees may be found in any habitat that has trees or woody shrubs, from forests and woodlots to residential neighborhoods and parks, and sometimes weedy fields and cattail marshes. They frequently nest in birch or alder trees.
🌳Black-capped Chickadee in the backyard:
Chickadees are one of the easiest birds to attract to feeders, for suet, sunflower, and peanuts. They readily visit window feeders. The Black-capped Chickadee hides seeds and other food items to eat later. Each item is placed in a different spot and the chickadee can remember thousands of hiding places. Chickadees will take seeds from feeders and trays over to a tree branch to hammer them open.
🪺Black-capped Chickadee Breeding:
Black-capped chickadees usually breed only once a year. And their hatchlings are altricial, naked with their eyes closed. Nestlings are fed by both sexes but are brooded by the female only. Young leave the nest 12–16 days after hatching, in great part because the parents start presenting food only outside the nest hole. The young are still fed by the parents for several weeks but are capable of catching food on their own within a week after leaving the nest.
🌟Black-capped Chickadee and its similar species:
The most similar species of Black-capped chickadee is Carolina Chickadee.
Carolina and Black-capped chickadees have very little range overlap, so check range maps, strong contrast in the wings and the very large white cheek patch, and listen to Carolina's 4-noted song(Black-capped chickadee: See-bee or See-bee-ee/ Carolina Chickadee: See-bee--see--bay).

Bird Introduction-Blue Jay

The blue jay, with its bold coloration and even bolder personality, is one of the most common and familiar backyard birds in the eastern United States.
📝Basic Info:
  • Scientific Name: Cyanocitta cristata
  • Common Name: Blue Jay, Jay
  • Lifespan: 6-8 years
  • Size: 11 inches
  • Weight: 2.5-4 ounces
  • Wingspan: 16 inches
🌎Blue Jay Distribution and Habitat:
Blue Jays are common throughout the eastern and central United States and southern Canada from the Atlantic coast to the Rocky Mountains and eastern Texas. These birds are highly adaptable to different habitats and can be found in different types of forests as well as cities, parks, and suburban areas where mature trees are present.
🐦Blue Jay in the backyard:
Blue jays are omnivorous birds and opportunistic feeders that may sample just about anything available. Nuts, berries, seeds, corn, carrion, insects, eggs, and even small animals such as lizards or baby birds may be part of their diet, and they easily switch to different food sources at different times of the year. Blue jays are also attracted to water and will frequently visit bird baths for drinking and bathing. Planting oak trees will also help provide a natural nut source to attract blue jays.
🌟Blue Jay Conservation:
These jays are not considered threatened or endangered in any way, and their adaptability serves them well for adjusting to new habitats or habitat changes. Outdoor and feral cats can be a threat in urban and suburban areas.
📖Blue Jays in Culture:
Because these birds are lovely, distinctive, and intelligent, they are popular mascots for schools as well as sports teams. Also in some tales, the blue jay was credited with making the earth "when all de world was water" by bringing the first "grit" or "dirt." In other tales, the blue jay was temporarily conscripted as a servant of the Devil, and would not be seen on Friday as it was gathering twigs to furnish Hell's kindling and give fire to wicked men on Earth; relieved from duty on Saturday, its song for the day was abundant and joyous.

Bird Introduction-Northern Cardinal

With its instantly recognizable bright red or reddish tan plumage, jaunty head crest, and distinctive face mask, the northern cardinal is one of the most desirable backyard birds in North America.
📝Basic Info:
  • Name: Northern cardinal(cardinal, Virginia nightingale, common cardinal)
  • Lifespan: 3-5 years
  • Size: 8-9 inches
  • Weight: 1.5-1.7 ounces
  • Wingspan: 10-12 inches
🌎Northern Cardinal Distribution:
Northern cardinals are common throughout the eastern United States from Maine to Florida and spanning west to southern Minnesota, Nebraska, Texas, and the east half of Mexico. They also live in northeastern Canada: Ontario, Quebec, New Brunswick, and Nova Scotia.
Look for Northern Cardinals in inhabited areas such as backyards, parks, woodlots, and shrubby forest edges. Northern Cardinals nest in dense tangles of shrubs and vines.
🌳Northern Cardinal in the backyard:
These birds are omnivorous. They will eat many different food sources, including insects, seeds, fruit, nuts, sap, berries, cracked corn, and suet. And they can be shy and skittish at feeders and may be easily spooked by larger or more unruly birds such as grackles or jays.
🌟Distinguish between male and female Northern Cardinals:
Male cardinals are brilliant red all over, with a reddish bill and black face immediately around the bill. Females are pale brown overall with warm reddish tinges in the wings, tail, and crest. They have the same black face and red-orange bill.
🎈Flock behavior:
①Both male and female northern cardinals are adept songsters, and males, in particular, may sing year-round. Females often sing while sitting on the nest, which may communicate the need for more food to their mates. Females also often have more elaborate songs than males. One cardinal may have more than a dozen song variations, and different geographic populations often have quite different songs.
②The male often feeds the female as part of their courtship behavior.

Birds have thousands of feathers, and each one is subject to wear and tear, which leads to molting. So what is molting and how do birds molt? Let's talk in today's BirdTips.
Molting is the process by which birds shed old or worn feathers and grow new ones to replace them. A molt may be partial and replace just some of a bird's feathers or complete when all the feathers are replaced at once. According to different species, the time it takes to complete a molt is also different. It can take as little as two weeks, or as long as several years. Some birds molt their feathers only once a year, while others molt many times.
In general, feathers are molted in a symmetrical pattern across the bird's wings, tail, and body so it retains its balance for flight. The entire cycle typically takes 5-12 weeks.
As feathers age, the quills loosen in their shafts and it is not until they are ready to fall out that new feathers begin to grow. The new feathers then create visible gaps in a bird's plumage, particularly in the wings and tail where shorter feathers are more noticeable.
Molting requires a tremendous amount of energy, and birds do not molt during the breeding season or migration periods when that energy is needed for nesting or traveling. The most common molting period is just after the breeding season when food sources are still abundant. The second most common period is just before the breeding season when food sources are increasing.
🔴Tips: Unlike hair and fingernails that continually regenerate and grow, a feather is a complete structure and no longer grows once it reaches full size.
Backyard bird feeders can help ease the dangers of molting by providing a rich, reliable food source for birds to take advantage of, along with safe, secure shelter for birds that become more elusive and shy while molting. If birds trust their habitat to meet their molting needs, they will stay around during this uncertain period, giving bird feeders the opportunity to witness molting firsthand and enjoy ever more intimate knowledge of their favorite feathered friends.
Well, anyway, looking forward to seeing their beautiful new feathers.

Eight types of bird seeds for Birdfy and their advantages & disadvantages

For Birdfy, there are many kinds of bird food we can put, mealworms, peanuts, fruit, and seeds. One of the most important components is seeds. Seed is a large range that contains eight different species, mainly has got black oil sunflower seed, striped sunflower seed, Safflower Seed, and so on. Now let's analyze their advantages and disadvantages.
  1. Black oil sunflower seed
Black oil sunflower seed is a key component of many bird seed mixes. The seeds have thin shells and a high oil content that appeals to the majority of bird species. And you can also grow and harvest black oil sunflower seeds during the summer months.
However, squirrels love these seeds, too. Make sure you can protect the feeder from squirrels because they will snatch all the black oil sunflower seeds.
  1. Striped sunflower seed
Striped sunflower seed is similar to black oil seeds, striped sunflower seed is a good high-fat, high-oil seed that many birds will sample. And maybe it is good news that squirrels seem like they don't like this seed.
But because the seed is thicker and harder than black oil sunflower seed, the striped seed may be eaten last as birds naturally seek out easier, more convenient foods first.
  1. Safflower seed
Safflower looks like a white sunflower seed, safflower is actually a completely different plant. The white seeds are favorites of doves, titmice, and cardinals. Safflower is generally more expensive than other seeds and may be mixed with sunflower chips or millet in premium mixes to be more affordable and appealing to more bird species. Because this seed has a somewhat bitter taste, it is usually neglected by squirrels and other wildlife.
  1. Hulled Sunflower Seed
These seeds already have the hulls removed, there is no waste left around the Birdfy. Hulled sunflower seeds are rich in oil and a high source of calories for birds. Hulled seeds are more expensive than regular sunflower seeds. All songbirds, including finches, sparrows, cardinals, titmice, and chickadees, enjoy hulled sunflower seeds.
Hulled sunflower seeds are ideal for winter bird food. Birds do not need to waste energy trying to remove the hull to open seeds.
  1. Nyjer
Nyjer is a kind of oil-rich, high-fat, high-protein seed. And Nyjer is a favorite seed for many small birds, including siskins, goldfinches, redpolls, and juncos. While Nyjer is more expensive than larger seeds, it is a good economic value because little is wasted.
  1. Millet
Millet is a grass seed that's very popular with small birds. It is available in both white and red varieties, and both are suitable as food for backyard birds. Millet is high in starch, protein, fiber, and fat, and is a good food source for small birds.
But it's important to keep the millet as dry as possible. Only set out a little bit that can be eaten in a day.
  1. Cracked corn
Cracked corn is a part of seed mixes. It is a very economical type of grain, and easily available not only at wild bird stores but also at agricultural feed stores and many garden centers.
A good source of both oil and starch, cracked corn is inexpensive. Offering cracked corn sprinkled directly on the ground, or mixed in with other types of seed is very easy for bird feeders to prepare. But cracked corn is prone to rotting and mold as a result of moisture.
  1. Red Milo
Milo is a filler seed with poor nutritional value for birds, but it does offer some iron, fiber, and calcium for birds that eat it. This grain is available in both red and white varieties. Because it is large and bulky, it is less expensive than most other types of bird seed.
To avoid excessive wasted seed or spillage, it may be best to offer this seed in limited quantities and only refill the seed when it is completely consumed.
