And of eggs and nests and birds on nests. Into the Nest , as the title says, is about the courting, mating, egg-laying, nesting, and parenting behavior of “familiar birds”. Some chapters focus on one species (Yellow Warbler), some on several related species (Chickadees and Nuthatches). And of birds courting and mating.

Twenty two species are distributed among six genera, depending on what happens to be extinct, and for the most part one grebe is like another. This makes Grebes vulnerable to climate change and the predation of invasive species. It is easy to see how Minks set lose in a welcoming habitat could eat an entire species.

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.

I think most of us in North America have come to the somewhat disappointing conclusion that fall migration is pretty much finished for the year. The flocks that just a fortnight ago held multiple species in varied, if subdued, hues, now overwhelmingly consist of a single species. You’re done. Look at those bright legs!

There was a time when I thought each bird species had its own individual song.
