For example , in one study, it was found that more than 80 percent of the fledgling Australian Magpies born in a territory one year were sired by males from outside its borders. When these birds breed, this can lead to highly cringeworthy announcements, for example from Adelaide Zoo : “We have egg-citing news!”

These run the range from birds like Barnacle Goose and Little Egret, which are rare but do show up in North America every few years (actually, lately it’s been every year) to birds whose sightings in North America are so few that they’re legendary–Western Reef-Heron and Corn Crake are two examples. This is not unusual.

As you can easily judge from the dullness of this information, it is not something I made up but rather an appalling example of nepotism in the naming of birds. The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. Sir James McGrigor (1771-1858) Director Gen.

The species are taxonomically divided into two families: Tytonidae, Barn-Owls, and Strigidae, Owls, encompassed in one order, Strigiformes. The chapters on courtship and breeding and roosting and migration are the longest, which isn’t surprising. It’s a lot of work. It sounds like fun, but I can’t find it anywhere.

Some other members of the shrike family were a bit less testosterone-driven at Nanhui – like this Bull-headed Shrike … … this rather attractive-looking Tiger Shrike … … or one of the many Brown Shrikes passing through Nanhui on migration. Then, I was not sure whether this was the right thing to do. ” Hm.

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.

The story of the cahow, a “Lazurus species” that was thought to be extinct for over 300 years and then discovered to be breeding on a tiny remote island in Bermuda, is part of modern birding legend. It is hypothesized, for example, that nocturnal seabirds like the Bermuda Petrel eat bioluminescent prey.

Breeding behaviour and plumage was very apparent, but John Wise , an ex-pat Brit now resident in Orlando, told me that the birds’ activities had been held up for a couple of weeks during a cold snap that saw frosts in Florida. Boat-tailed Grackles count eggs and chicks as part of their diet and they were well represented here today.

It is organized taxonomically, with families identified by first scientific and then popular name. Each family section starts with a brief description of the birds within that family, their common physical and behavioral traits, and range of habitat. Even during the breeding season the birds appear to be quite unwary of humans.

This is how, I think, the “Crossley technique” works best—coverage of specific bird families that pose identification challenges to birders at all levels of skill. Which is why I chose this particular duck as my example. The plate on Mystery Brant, for example, refers the reader to page 234 for answers when it should be page 485.
