In some cases, for example Jabiru, the information is tucked away at the end and can’t even be discerned from the range map. Yes, it’s nice to have information on 817 birds, and it’s wonderful to have full descriptions and photographs of birds commonly seen in Central and South America. SPECIES ACCOUNTS.

Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale. Conservation organizations such as the Flamingo Specialist Group is actively trying to inform the public on the vulnerability of flamingos.

Hints of potential warming in the HBW species description: “Date of first egg-laying on Honshu now 7 days earlier than it was 25 years ago” There are also quite a few Cuckoos.

With populations plunging dramatically over the last decade, researchers from the Wildfowl and Wetlands Trust, Birds Russia, and a number of other conservation organizations made the always-controversial call to pluck eggs from the imperiled wild population and establish a captive breeding program as a final hedge against extinction.

We have had a very poor breeding season for our resident shorebirds and in particular none of the 16 pairs of Pied Oystercatchers along the 23 kilometre/14 miles stretch of coast that we keep an eye on have successfully bred. All of the migratory shorebirds had started to leave Broome and it appeared it had also gone north.

The nickel was placed in the nest for the photo to show me the size of the egg for identification purposes, then removed. Even though the female lays only two eggs per nest attempt, they enjoy a protracted breeding season in which multiple nesting attempts can occur every 30 days, and in Southern locations, nearly year round.

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.

A study on the breeding biology of Whitehead’s Broadbill was just published in May 2023 but leaves a bit of a puzzle as the breeding success is described as relatively high, meaning there should be other reasons for the population decline of the species.
