There are sixteen pairs of Pied Oystercatchers and they have varying success at raising young birds. To the north they are very unlucky with predation before the eggs even hatch out, but to the south the eggs hatch out and then the predation occurs on the chicks.

While having somebody else raise your chicks like an attractive strategy to me, it is not without dangers. The Journal “Advances in Ophthalmology & Visual System” is not a regular source for bird-related information. A paper reports on how a female Common Cuckoo was mobbed and killed by Oriental Reed Warbler hosts.

If you want to see photos of all 8 of them, there is a nice one-page leaflet online which is also the source of some of the information below. Another paper reviews information on Oriental Pied Hornbills raiding the nests of various bird species in Singapore and even pet bird cages. A good reason to come back soon then, I guess.

Actually, as I just found out, this is not really new information. 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). but they do. See the sequence below.

But a Bewick’s Wren did build a nest, which it promptly abandoned before laying any eggs. But perhaps “tweets” simply went out that Aldea is a great place to raise chicks. We at NestWatch are very excited that this group has burst onto the scene and quickly become our primary source of information about this species.

I couldn’t help thinking this–me, the anthropomorphism hater– as I watched a pair of Philippine Eagles tend their nest, raise a chick, and tear monkeys apart in Bird of Prey: The Story of the Rarest Eagle on Earth , a well-crafted, beautifully filmed documentary with a mission. The Philippine Eagle has a kind face.

In this way, the cuckolding Cuckoo can convince its cuckoldee, the Reed Warbler, to back off when the Cuckoo comes around, allowing the Cuckoo to toss out one of the Warbler’s eggs and replace it with one of its own, to be raised by the hapless Warbler parents. However, Reed Warblers are social learners.

In the former, a female lays her fertilized egg in the nest of another species, in the hopes that her offspring will be raised by the unwitting hosts. In the latter, three or more adult individuals contribute to the raising of offspring. It turns out that the two strategies may be related.

Birds are raised from the egg to follow a certain migration timing, but that timing shifts when the egg hatches later or earlier due to changes in conditions. We are probably at the point where there is enough information out there that we can have a rational discussion of this important issue.

As a Northeast birder I am familiar with the alarming decrease in the number of Red Knots along Atlantic shores and have signed petitions and written e-mails calling for legislation and rules that will limit the overharvesting of the horseshoe crab, whose eggs Red Knots depend on. The visual beauty and textual facts are a strong combination.

I once knew a guy who kept and raised cats. The plethora of approaches to the feral Cat problem is not an outcome of a diversity of great ideas; it is the ugly chimera of inappropriate compromise among biased and often poorly informed stakeholders. But they don’t live in North America. Unless we put them there. Plus, Coyotes eat Cats.

There is overlap with its companion field guide, Dragonflies and Damselflies of the West (the current total number of odonate species in North America is 462), and Paulson has made an effort to limit the amount of duplication, using different photographs for overlapping species and updating species accounts with new information.

How many eggs did a pigeon lay? He reasons out answers to both questions, finally stating that, despite what many eyewitnesses wrote, the birds had to have laid more than one egg and that the birds had to have nested more than once a breeding season. Avery offers some interesting insights into the biology of the Passenger Pigeon.

Her use of the term food “fashion” is appropriate: many people today do not make informed choices about their diet; rather, they are influenced by trends, advertising and the political correctness of food. It is well settled that a balanced diet of these foods provides the same essential amino acids that Nina Planck finds in an egg.
