According to Tim Low (in “Where Song began”), “so easy were they to breed that by 1859 they cost less to buy in London than in Sydney.” ” Funny how the difficulty of breeding a species can be illustrated in simple monetary terms. Is it offensive to say that Australian Zebra Finches breed like rabbits?

Also from BirdLife International: In general it prefers areas where vegetation, boulders or other landscape features at ground level provide tunnels in which to shelter and to breed. Its eggs are not known, it does not migrate, and it feeds, I understand, on insects and worms. The bird will therefore now be known as.

Scientists were largely limited to studies birds in breeding colonies, at least those we knew about and that were accessible (and, if you think that’s a complete list, you haven’t read the news that came out this week about a new colony of Adélie penguins found in the Danger Islands, Antarctica). Technology to the rescue!

They breed in colonies scattered around the Antarctic continent (the number ranges from 60 to 70, and as Kooyman points out, the colonies can drastically change in size from year to year) on the ice (and one of the things I learned from this book is how many different kinds of ice there is in the Antarctic) in the darkest months of winter.

Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea. They have special adaptations to stay warm and to keep their eggs and chicks warm. Salas-Gismondi, R., Altamirano, A., Shawkey, M., D’Alba, L., Vinther, J., DeVries, T., & Baby, P.

The fields near the Tiaozini mudflats look very much like a lunar landscape, but this does not seem to keep a number of species from breeding there, sometimes directly on dirt roads. But now back to birds … Little Ringed Plovers also seem to like to breed directly on the road. Blandness sells.

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. The investment placed in each clutch bur seabirds is so great that only one breeding attempt can be seen to completion each year.

Earlier attempts to spread the risk around had failed, so Don and his team applied science to the problem, spending several months studying the birds in the wild in order to work out how to care for them and to decide what type of habitat to release them into. It worked, and the translocated birds were soon breeding.

Hopefully, the winter time in Shanghai gives the Black-faced Buntings some time to relax from the challenges of the breeding season.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.
