And they were intrigued and they had questions, lots of questions, more questions than could be answered by a field guide or a social media group.

There are currently 10 species of Treecreepers that form the family Certhiidae, nine in the genus Certhia and an additional oddball in another genus, Salpornis. David Sibley (yeah, the one ) recently raised the question visiting birders (particularly from Germany, not so much from the UK – I am told!) I’ll explain.

In the former, a female lays her fertilized egg in the nest of another species, in the hopes that her offspring will be raised by the unwitting hosts. In the latter, three or more adult individuals contribute to the raising of offspring. fledglings per group per season. It turns out that the two strategies may be related.

Seabirds are one group of birds that go for the latter strategy. A few families have a small number of eggs in the clutches, like gulls or cormorants. Unique among the auks, indeed among seabirds, they will attempt to double brood, to lay another clutch after successfully raising the first chick. So why do it?

My friend Vickie Henderson , who has some serious long-range vision, looked at the science behind Tennessee’s crane hunting proposal and found it badly wanting. Letters from Eden (Houghton Mifflin, 2006) will soon be followed by a memoir about the birds she has raised, healed, studied and followed throughout her life.

Of the Central Flyway states, Nebraska alone holds out in protecting the cranes, having proven by its longstanding Festival of the Cranes in Kearney that a crane is worth infinitely more alive and purring in the sky with its family than thudding, broken and bleeding, into a cornfield.

Itcher birds, migratory members of the tern family. If migration evolved many times in birds, then it would be worth asking if it evolved in birds more often than in other groups of vertebrates. Another question this raises has to do with migration itself. People were doing things like that with birds, sharks, and humans.

It is mostly a question of economics – raising just one is troublesome enough given the resources required to feed and educate the chick. Like this bird family b. Chongming Dongtan, where these photos were taken, is the wintering location of about 100 Hooded Cranes – about 1% of the global population. Like bad jokes and c.

This of course raises questions of what happens when all of the inland nesting grounds of all the loons becomes covered with glacial ice during ice ages, then later, the ice melts and the lakes return. . – I love participating in citizen science! And a lifer for me – if I manage to see it! I was beginning to stress….

Science and Conservation , the second section, presents two-page summaries of the diverse research being done around the world about penguins. Raised in the Galapagos, she’s been exposed to penguins her whole life. That’s a lot of books about a bird family that cannot fly. I like it, but I also feel frustrated by it.
