about the finch from to kill a mockingbird.

If you didn't know they don't actually kill a mocking bird cause its a sin to.

The House Finch is a recent introduction from western into eastern North America (and Hawaii), but it has received a warmer reception than other arrivals like the European Starling and House Sparrow. That’s partly due to the cheerful red head and breast of males, and to the bird’s long, twittering song, which can now be heard in most of the neighborhoods of the continent. If you haven’t seen one recently, chances are you can find one at the next bird feeder you come across.

House Finches are small-bodied finches with fairly large beaks and somewhat long, flat heads. The wings are short, making the tail seem long by comparison. Many finches have distinctly notched tails, but the House Finch has a relatively shallow notch in its tail.
                  

Color Pattern

Adult males are rosy red around the face and upper breast, with streaky brown back, belly and tail. In flight, the red rump is conspicuous. Adult females aren’t red; they are plain grayish-brown with thick, blurry streaks and an indistinctly marked face.

Behavior

House Finches are gregarious birds that collect at feeders or perch high in nearby trees. When they’re not at feeders, they feed on the ground, on weed stalks, or in trees. They move fairly slowly and sit still as they shell see

Habitat

House Finches frequent city parks, backyards, urban centers, farms, and forest edges across the continent. In the western U.S., you’ll also find House Finches in their native habitats of deserts, grassland, chaparral, and open woodsds by crushing them with rapid bites. Flight is bouncy, like many finches.

Similar Species

House Finches have blurry grayish streaking on the belly and flanks, unlike either Cassin's Finch or Purple Finches. Female House Finches have a plainer brown head, where female Purple Finches are more strikingly brown and white. Female House Sparrows have light-brown stripes on the back and are unstreaked on the chest and belly. Bill shape is distinctive for House Finches: it's fairly blunt, and rounded, without a sharp tip. Purple and Cassin's finches both have longer, less rounded bills. Pine Siskins are even more streaky than female House Finches, with yellow patches in the wings and a thinner, more pointed bill. Female House Sparrows are warmer brown above and don't have streaked underparts.

Regional Differences

House Finches, particularly males, can look very different from one to another. This is largely due to differences in their diet rather than regional differences. Even though all of eastern North America’s House Finches are descended from the same few birds released on Long Island (meaning they’re much more closely related to each other than they are to birds across the West), there aren’t any strong differences in size, shape, or color between the two regions

Cassin's Finch

Adult male
  • Similar to male House Finch
  • Red on face is more intense and extends farther towards nape
  • Less streaking on sides (finer on flanks)
  • Longer, more pointed bill than House Finch
  • Adult male

    Cool Facts

    • The House Finch was originally a bird of the western United States and Mexico. In 1940 a small number of finches were turned loose on Long Island, New York, after failed attempts to sell them as cage birds (“Hollywood finches”). They quickly started breeding and spread across almost all of the eastern United States and southern Canada within the next 50 years.
    • The total House Finch population across North America is staggering. Scientists estimate between 267 million and 1.4 billion individuals.
    • House Finches were introduced to Oahu from San Francisco sometime before 1870. They had become abundant on all the major Hawaiian Islands by 1901.
    • The red of a male House Finch comes from pigments contained in its food during molt (birds can’t make bright red or yellow colors directly). So the more pigment in the food, the redder the male. This is why people sometimes see orange or yellowish male House Finches. Females prefer to mate with the reddest male they can find, perhaps raising the chances they get a capable mate who can do his part in feeding the nestlings.
    • House Finches feed their nestlings exclusively plant foods, a fairly rare occurrence in the bird world. Many birds that are vegetarians as adults still find animal foods to keep their fast-growing young supplied with protein.
    • The oldest known House Finch was 11 years, 7 months old.
  • House Finches are familiar birds of human-created habitats including buildings, lawns, small conifers, and urban centers. In rurual areas, you can also find House Finches around barns and stables. In their native range in the West, House Finches live in natural habitats including dry desert, desert grassland, chaparral, oak savannah, streamsides, and open coniferous forests at elevations below 6,000 feet.
  • House Finches eat almost exclusively plant materials, including seeds, buds and fruits. Wild foods include wild mustard seeds, knotweed, thistle, mulberry, poison oak, cactus, and many other species. In orchards, House Finches eat cherries, apricots, peaches, pears, plums, strawberries, blackberries, and figs. At feeders they eat black oil sunflower over the larger, striped sunflower seeds, millet, and milo.
  • A House Finch’s nest is a cup made of fine stems, leaves, rootlets, thin twigs, string, wool, and feathers, with similar, but finer materials for the lining. Overall width of the nest is 3-7 inches, with the inside cup 1-3 inches across and up to 2 inches deep.
    Nest Placement

    Tree
    House Finches nest in a variety of deciduous and coniferous trees as well as on cactus and rock ledges. They also nest in or on buildings, using sites like vents, ledges, street lamps, ivy, and hanging planters. Occasionally House Finches use the abandoned nests of other birds.

Ground Forager
A highly social bird, the House Finch is rarely seen alone outside of the breeding season, and may form flocks as large as several hundred birds. House Finches feed mainly on the ground or at feeders or fruiting trees. At rest, they commonly perch on the highest point available in a tree, and flocks often perch on power lines. During courtship, males sometimes feed females in a display that begins with the female gently pecking at his bill and fluttering her wings. The male simulates regurgitating food to the female several times before actually feeding her.

Conservation

status via IUCN

Least Concern
House Finches are common and they generally benefit from human development. However, populations underwent a steep decline beginning in January 1994 owing to a disease called mycoplasmal conjunctivitis. The disease causes respiratory problems and red, swollen eyes, making them susceptible to predators and adverse weather. House Finch conjunctivitis was first observed at feeders in the Washington, D.C., area. It’s not harmful to humans, but it has spread rapidly through the eastern House Finch population and into the West.

Bullfinch
Bullfinch
Although fruit-growers who've suffered from the depredations associated with the bullfinch might concur that its title could be a problem of bullfinch, it's present title, however produced, seems adequately apt, in order for there is something bull-like regarding the thick-set build as well as somewhat pugnacious facet of this bird.
Within character, nevertheless, it does not live up to it's name, for this is one associated with the shyest and most deceptive of birds-so much that, as soon as the observer continues to be alerted through the fluting call, the most common view acquired is of the bird with a noticeable white rump retreating in to the nearest include.
But, where ever there are apples, pears, peaches, walnuts, Japanese quince, forsythia or even gooseberries visible through indoors, eventually, in town or even country, the householder is nearly certain to come with an opportunity to view this good looking bird at near quarters.
Appreciation mingled with exasperation is actually the usual response, but there are several extremists who voluntarily accept the short lived beauty of this kind of visitations, even from the cost of blossom-less bushes and ineffective trees.
However commercial fruit-growers can't afford such higher aesthetic requirements, and no one that has seen the total barrenness of a plum-orchard carrying out a few days' interest from bullfinches within the preceding winter season, can neglect to understand why, such areas, this particular bird is no longer upon the protected checklist.
But great slaughter in fruit-growing places seems to have carried out little to lessen numbers, and also, since the years by which bullfinches become unwanted pests are rarely sequential, it seems not likely that this approach to control may succeed.
It may be thought that many years of widespread bullfinch harm must match with highs in bullfinch populace, and that many years of respite are warning signs of poor reproduction seasons as well as lowered amounts; but this doesn't seem to be the situation.
The plump flower-buds associated with trees and shrubs tend to be apparently another or book diet just resorted in order to when the choice winter meals, the seeds of some favoured types of trees, aren't available. Therefore in the snow-bound winter season of 1962-63, within an area exactly where bullfinches had done a lot damage within the previous winter season, the feared intrusion of the orchard by no means came, and also at first it had been assumed there was not one in the area.
Tell-tale evidence of vacant ash-keys beneath the tree not really two hundred yards aside led to the breakthrough of a every day feeding flock around twenty birds. Just like this meals was almost finished, the unfreeze came as well as exposed a good untouched floor supply of the subsequent most popular seed products, those of sycamore as well as maple. The bumper harvest of apples, pears and apricots followed.
If you watch a bullfinch coping with such large-kernelled tree-seeds the purpose of the specialised heavy bill as well as wide gape gets apparent. The fresh fruit is altered by expenses and language until the toned seed-bearing portion is actually vertical; stress is then utilized, and the encircling envelope breaks; a movie of the heavy tongue, as well as the seed is actually extracted as well as the empty situation ejected.
Bird Details
Haunts: 
In reproduction season forest, large bushes or shrubberies, so long as some thick cover, at the.g. evergreens or even blackthorn thicket, is available. Within winter as well as spring landscapes and orchards, but additionally weedy wastes exactly where it may go with other finches.
Appearance: 
About sparrow-sized, however with stouter body as well as shorter thighs. Both genders recognisable by blackcap, dark, grey-barred wing, really conspicuous whitened rump-patch, and dark tail. Broad, deep however short expenses, and instead flat overhead form user profile that is unshakable. The male offers well demarcated color zones-uniform pale gray back, brick-pink underparts conference black overhead on degree with attention; whiteness of rump highlighted by shiny black associated with tail as well as wing. Common pattern associated with female for male, however duller and fewer clear-cut colours. Youthful lack dark caps, and therefore are altogether browner, however already have special rump, wing as well as tail marks.
Voice: 
The musical, instead plaintive fluting call 'pew-pew' or even 'pew-pew-pew'; soft, however carries nicely. No accurate song, even though slight versions of phone notes might be detected within breeding period.
Food: 
Primarily vegetable; along with seeds as well as buds currently referred to, additionally fond of amalgamated seeds- groundsel, dandelion and plant thistle. Too heavy in order to perch on these types of as goldfinch will, and therefore frequently overlooked whenever feeding on groundsel amongst weed-cover. Young given by regurgitation- bugs, spiders as well as small snails generally present in common mash of seedling and greens. In winter season some fruits eaten, the ones from privet especially.
Nesting: 
Thick thickets or shrubbery of many varieties; favourites tend to be blackthorn, box, philadelphus, snow-berry. Home often relatively flimsy framework of fine sticks, but usually with well-made heavy cup of proper root-fibres with occasionally a little locks. Eggs greenish-blue, along with spots as well as streaks associated with purplish-brown, mainly from big finish. Two broods are normally elevated each period.
