The Cowbird never has its own nest - it uses the finch nest as its host (read: parasite.) The Cowbird egg will hatch first & will push the other eggs or baby finches out of the nest. Other species of birds will get rid of the Cowbird eggs, but finches don't seem to. I always remove them when found.
some are. There are soooooooo many types of finch, some of their eggs are blue, some are white with brown spots.
YES!!!!!!!!!!!!
2 a millenium
they can lay 4 to 6 eggs
The incubation period for finch eggs is typically around 12-14 days, though this can vary slightly depending on the specific species of finch. During this time, the parent birds will take turns sitting on the eggs to keep them warm until they hatch.
you decide
One reason why is that the eggs are not fretilized and they dont want to waste there time on them or the egges are dead.
ummm I would think so.
Roughly 22 x 16mm, 3g
14-16 days.
it would take about 1 month so that the finch would be able to settle down
