House Finch
The House Finch was originally a bird of the western United States and Mexico. 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. Since January 1994, House Finches have been detected with a disease called mycoplasmal conjunctivitis that causes respiratory problems and red, swollen eyes. It can kill House Finches directly or make them easy prey. 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. Habitat 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. Nesting Habits The female lays 2 to 6 bluish with fine speckling eggs. Incubation is done by the female for 12 to 14 days and the young will leave the nest in about 11 to 19 days after hatching. During the incubation time and for about five days after the young have hatched, the male, will feed the female on the nest. He does this by regurgitating seed into the females mouth. The female regurgitates the food to the nestlings. After the young have fledged, the parents continue to feed the young. The female may find a new mate and raise another brood while the male continues to feed the young. House finches have been known to raise more than two broods in a season. In response to mite infestation, the mother finch may lay one gender of egg first, which increases the chances of the young finches' survival. The female incubates the eggs for 12 to 14 days. Shortly after hatching, she removes the empty eggshells from the nest. The hatchlings are pink with closed eyes and tufts of fluffy down. The female always feeds the young, and the male usually joins in. Before flying, the young often climb into adjacent plants, and usually fledge at about 11 to 19 days after hatching. Dandelion seeds are among the preferred seeds fed to the young. House Finches are aggressive enough to drive other birds away from places such as feeders. Data from the Internet |

It is somewhat unusual that they are vegetarians and don't eat worms like other birds.
They mainly eat seeds. No wonder they always take over the bird feeders with seeds at my home.
In that case, the mother bird has to regurgitate to feed her babies.
I was surprised to find a phrase that "They build their nest on Christmas wreaths."
Our wreath wasn't for Christmas but they wouldn't know the difference.
I am glad that I get to know them a little better.
고향의 참새: 크기와 모양이 비슷하게 보이지만,
우리가 알고있는 한국의 "참새"와는 다른 새종류이다.
물론 같은 family에 속할지는 모르지만.
여기의 참새 사진을 자세히 보면 전혀 다르다는것을 알수있다.
참새는 Asia와 Europe에 있고 미주대륙에는 없는것으로 되어있다.
우리가 아는 한국의 참새는 영어로 Eurasian Sparrow, True Sparrow, or Old World Sparrow이며,
American Sparrow와는 Family가 다른 종류라한다.
