They bred on a number of islands near Japan and Taiwan, and ranged widely and abundantly from the Aleutian Islands south through California. The most notorious effect is that their eggshells become so thin that a parent bird will crush it’s eggs while attempting to incubate them.

With a hardiness that belies their delicate looks (but helps explain their phenomenal success), these pioneering pigeons are already sitting on eggs at at least one location in Montana. So right now I’m feeling pretty good about Eurasian Collared-doves.

The species was seemingly killed off by feather hunters, but then, after years, reappeared at the site of one of the deserted breeding colonies, Torishima Island in Japan. She’s described conservation successes in detail–the Bald Eagle, the Short-tailed Albatross, now protected in Japan.

According to the HBW, food brought by Siberian Blue Robins to nestlings in Japan was 36% adult insects, 28% insect larvae, 18% spiders, and 18% unidentified (I suspect the last mostly being unhealthy fast food with the discriminating labels ripped off). Here at 10,000 Birds, we never forget that you, the reader, have a choice.

Alternatively, imagine I set the dial to produce simple heat, like the kind that comes out of your stove to cook your scrambled eggs. The kind of energy produced by a cell phone signal is way more like the heat that cooks your eggs than like the scary radiation that comes form an H-bomb or X-ray machine or whatever. 0016862 a.

Of course, it is hard to resist looking at a paper titled “Host personality predicts cuckoo egg rejection in Daurian redstarts” Basically, the personality of a female redstart (bold or shy) predicts the responses to parasitic eggs – bold hosts are more likely to reject parasitic eggs.

From Hiro, we learn how Northern Pygmy Owls are “rule breakers,” not incubating eggs till all are hatched and then raising owlets that mature at the same rate even though the eggs were laid asynchronously (as most owl eggs are).

I also enjoyed the breeding photo series, showing Downy Woodpecker eggs and then hatchlings within a breeding chamber in a tree, with only a few wood chips to support them. No political boundaries are indicated, which makes using the book awkward when the map and the textual range information are on different pages.

During March, 11 beats shared 122 checklists to accumulate 680 species from 8 countries; USA, Costa Rica, Serbia, India, Australia, New Zealand, UK and Japan. Jamaica Bay, Big Egg Marsh. In a blatant attempt to make the figures look even better than they already, any sightings shared with another beat will be counted twice.

Acariformes: Syringophilidae) from the Chestnut-eared Bunting (Passeriformes: Emberizidae) in Japan (morphology and DNA barcode data)” Ah, to be a scientist. Fortunately for the buntings, they seem to detect most cuckoo eggs smuggled in (75% in one study). Maybe there is some justice in this world after all.

The Large-billed Crow ( video ) is one of the natural enemies – in the study above, it predated 19 eggs from four pitta nests. This should not be a problem in Shanghai as the pitta has not been reported to breed here. Is it worth a scientific paper if a Large-billed Crow eats a fish?
