how long do finch eggs take to hatch
12 to 14 days
title: Red-tailed hawk text: the female while she incubates. After 28 to 35 days of incubation (averaging about three days longer in the Caribbean as does fledgling as compared to North American red-tails), the eggs hatch over 2 to 4 days. Like most raptorial birds, the nestlings are altricial and nidicolous at hatching. Hatchlings average in body mass with no difference in sizes of the sexes until the young are about 29 days old for mass and 21 days or so for external linear standard measurements such as bill and talon size. The female broods them while the male provides most of the food title: House finch text: 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. The young are silent for the first seven or eight days, and subsequently start peeping during feedings. Initially, the mother carries fecal sacs out of the nest, but when the young become older, she no longer carries them all away, allowing droppings to accumulate around the edge of the nest. Before flying, the young often climb into adjacent plants, and usually fledge at about 11 to 19 days after hatching. Dandelion seeds title: House finch text: takes place in the morning, at the rate of one egg per day. The eggs are a pale bluish green with few black spots and a smooth, somewhat glossy surface. In response to mite infestation, which has a more deleterious effect on male chicks than on females, the mother finch may lay eggs containing females first, in order to reduce the length of time male chicks are exposed to mites. This strategy increases the likelihood that representative numbers of both sexes will survive. The female incubates the eggs for 12 to 14 days. Shortly after hatching, she removes the empty title: Tree swallow text: rate. The tree swallow lays a clutch of two to eight, although usually four to seven, pure white, and translucent at laying, eggs that measure about . These eggs are incubated by the female, usually after the second-to-last egg is laid, for 11 to 20 days, although most hatch after 14 to 15 days. About 88% of nests produce at least one nestling, although this is lowered by poor weather and a younger breeding female. They hatch slightly asynchronously, with an average of 28 hours between the time the first and final egg is laid. The laying order predicts the title: House finch text: feeds the female during breeding and incubation of the eggs, and raising of the young, and the male is the primary feeder of the fledgelings (who can be differentiated from the females by the pin feathers remaining on their heads). Females are typically attracted to the males with the deepest pigment of red to their head, more so than the occasional orange or yellowish-headed males that sometimes occur. The female lays clutches of eggs from February through August, two or more broods per year with 2 to 6 eggs per brood, most commonly 4 or 5. The egg laying usually
