In California, coveys break up and pairs begin forming in February or March, followed by nest building and egg laying in May or June. She will usually lay 12 to 17 eggs, averaging five per week 1 , before beginning incubation. Occasionally, larger clutches occur due to egg dumping by other females. References: 1 Baicich, Paul J.

According to Wikipedia, birds (class Aves) are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates. Most researchers agree that modern-day birds are the only living members of the Dinosauria clade. After all, they are the species that got me started building nest boxes in the first place.

There was a time when I thought each bird species had its own individual song. Then I found out that there was this vocalization called a ‘call,’ so I thought each bird species had its own individual song (but just the males) and individual call. I do wish there was more about research on female bird song.

A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. One North American species I am very familiar with is the Cassin’s Auklet , which ranges from the end of the Aleutian Islands to California.

Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch.

According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. But maybe that is actually a good thing.
