Breeding bird surveys appears to show the resplendent Allen’s Hummingbird (like Corey’s capture, above) in decline—but not in Southern California, where examination of eBird data reveals that members of a residential population appear to be faring much better than their migrating brethren. sports championships ).

The goal of Around the World For Penguins is simple: Describe the 18 species of penguin and their breeding grounds “from the perspective of a traveller.” But, unlike most books focused on a bird family, this one is organized geographically. The full-length species accounts are not repeated.

Of the sixteen pairs of Pied Oystercatchers between Gantheaume Point and Willie Creek on the south side, which is a length of breeding territories covering 23 kilometres-just over 14 miles-only one chick fledges most years. There is egg predation, chick loss and sometimes possibly just some “bad parenting”!

In China, wherever there is one real tourist attraction (like the Great Wall), the local strategy seems to be to add some fake attractions – replicas of palaces or tombs, amusement parks, shopping centers – in order to maximize the income from tourists. But the starting point has to be a real attraction, not a fake one.

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.

Starvation and predators make it hard to grow up, and birds have evolved a lot of strategies to give (at least some of) their chicks the best chance in life. One strategy that varies among birds (and other animals) is the number of offspring. Seabirds are one group of birds that go for the latter strategy.

Gisela Kaplan has written a book about the species, and how they seem unperturbed by humans: “It’s one of their most successful defense strategies. When these birds breed, this can lead to highly cringeworthy announcements, for example from Adelaide Zoo : “We have egg-citing news! ” ( source ).

We are into the second attempt at breeding for this season in Broome for Pied Oystercatchers. The first eggs are laid during the first week of July each year and if these eggs fail to hatch or the chicks are lost they will lay further eggs within a few weeks. Nest site with 3 eggs-one white!

They are two strikingly different strategies, both of which seem to working well this spring, as everywhere one turns there is new life on the Tundra. Horned Larks breed widely over North America, including up here in the High Arctic. They are fed by one or both parents, even after they’ve fledged and left the nest.

Most Acorn Woodpeckers are cooperative breeders and live in family groups of up to a dozen or more individuals. Within a group, 1–7 male co-breeders compete for matings with 1–3 joint-nesting females who lay their eggs in the same nest cavity. This is a photo of a juvenile at my water feature.

During the breeding season, some Cattle Egrets look like teenage girls who have just discovered the existence of make-up, and consequently massively overdo it. While having somebody else raise your chicks like an attractive strategy to me, it is not without dangers. It is probably all downhill from here. What’s next?

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. And Hybrids: Waterfowl tend to hybridize to a greater degree than most other bird families, and the guide does an excellent job of covering hybrids. Barker and Carrol L.
