Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch. Egyptian Vultures raised is isolation used rocks to crack eggs presented to them. The behavior was inherent.

Raised in and around the West Texas steppe country where temperatures reached 100 degrees with regularity, he began life as the Dust Bowl and Great Depression converged. ” By 1970 the man who championed Peregrines had convinced Cornell University to build a Hawk Barn for captive breeding of these birds. He came for the hawks.

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. million in the late 1990’s. Should the gulls be controlled?

A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan. Previously, even researchers had problems getting access to nesting Kirtland’s Warblers.

If you remember that the first edition of Sibley was published with “National Audubon Society” on the cover, raise your hand.

Ackerman’s new book is about owls and owl research–the knowledge recently and currently being discovered through DNA analysis, new-tech tracking and monitoring, and old-fashioned fieldwork under the auspices of organizations like the Global Owl Project and the Owl Research Institute.

The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. Some Thai researchers looked at the breeding ecology of the Buff-breasted Babbler and published their findings in the somewhat unsuitable-sounding journal “Agriculture and Natural Resources”.

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. The Latin species name of the Penan Bulbul is ruficrissus.

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.

One paper describes them breeding in a human settlement in abandoned clay jars. When one Chinese researcher was very bored, he had a bright idea: Why not publish a paper on the complete mitochondrial genome of the Rhinoceros Hornbill ? Now pairs of hornbills feed outside this correspondent’s window”.

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. So why do it?

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. Or the destruction of the forests, food source and breeding grounds.

This week at 10,000 Birds, it’s all about how birds get around to bumping uglies (I’m talking about cloacas here), who they do it with, and how this actually leads to raising chicks…the birds and the bees of birds, you might say. Believe it or not, this is what “fidelity” looks like.

Take a look at this little Blue Tit and admit that you have never seen a more pathetic picture of a bird that combines the colours blue, yellow, green, white, and black in the most marvellous way you have ever seen: Recent research has shown that Leonardo da Vinci showed a Blue Tit to his model while he painted the smile on “Mona Lisa&#.

I guess most scientists would love to see their original research become the basis for a vast field of further studies. In terms of breeding behavior, starlings are a diversified group – some use helpers, others do not. She also laid eggs in Melba Finch nests. No doubt the woodpecker has similar considerations.

Given the complexity of the research, the result feels like a bit of a letdown – “northern populations start migration earlier than southern populations, especially in autumn” The species name of the Chestnut-eared Bunting is fucata , from the Latin “fucare”, to paint red. Better safe than sorry.

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). Black-naped Orioles are breeding in Fengxian. Here is a presumed pair. but they do.
