There is a fantastic paper just out in Science : “Sustained miniaturization and anatomoical innovation in the dinosaurian anceestors of birds” by Michael Lee, Andrea Cau, Darren Naishe and Gareth Dyke. Whales emerge from within the larger group of mammals that includes cattle, deer, pigs, camels, with camels being the most deeply rooted. (So
All species are from the ABA area, and all groups must meet at least one of these criteria: (1) the group “represented a good opportunity to build core birding skills,” (2) the authors thought it was a group that needed “a refreshed treatment,” (3) the authors were intrigued by the group and wanted to present it using their unique format.
Unfortunately, in the science of language, this does not sound particularly raunchy but rather like a rational decision: “A rare species such as the Chinese Pond Heron might choose heterospecific mates rather than abandoning all chances of reproduction.” This Cattle Egret has just read a paper stating that it would be 3.6
More than 150 bird species are known to have become extinct over the past 500 years, and many more are estimated to have been driven to extinction before they became known to science. The Gray Crowned-Crane is a new addition to the list of the world’s Endangered species, creeping up a category from Vulnerable.
The fields near the Tiaozini mudflats look very much like a lunar landscape, but this does not seem to keep a number of species from breeding there, sometimes directly on dirt roads. The fourth species apparently breeding on these fields is Grey-headed Lapwing. Much better than some fiddly spoon-billed sandpipers. Not this one.
The field site I am assigned to is located in one of the most diverse ecosystems in the world and home to a particularly rich avifauna that numbers well over 500 species. Hundreds of riotously colored birds representing 14 species of macaws and parrots flock and frolic together in less than fifty meters of forest canopy.
This leaves Shanghai in June with basically just the year-round species and the summer breeders, maybe with a few added ultra-lazy individuals of migratory species. Fortunately, there are a few more such breeding species than most Shanghainese are aware of. Such as the Black-winged Cuckooshrike.
Davis, an emeritus professor of animal science at Oregon State University, says the horses “damage” the environment. A total of 33,000 wild horses are degrading the environment, but around 3 million to 4 million cattle are not? Animals in nature don’t need to be controlled by a species that has such difficulty in controlling itself.
As a bird mainly feeding on seeds, it is regarded as a threat to crops (in fact, the Latin species name of oryzivora combines the words for rice, “oryza”, and eating, “vorus”). He is the great ascetic, the master of fertility, the master of poison and medicine, and Lord of Cattle.
Whatever it was, Corey was found at his keyboard 2 hours later, covered in blood and snot and sporting a cut lip, having announced that he and Mike would rescue the failing list by taking personal responsibility for adding 300 species.

They were my target species, and I remember being delighted in not only seeing them well, but finding feeding flocks that were remarkably unconcerned about being watched. On a visit in October 2022, I found ibises feeding with cattle in scruffy roadside paddocks adjacent to the marismas ( photographs below ).
They found 673 species and advanced the yearly total to 1019. Mark Hatfield Marine Science Center and Estuary Trail. Mark Hatfield Marine Science Center and Estuary Trail.

During October, 7 countries (Costa Rica, Australia, USA, India, Hong Kong, UK, Serbia) were birded by 11 beats who shared 135 checklists and noted 697 species. Cattle Tyrant – Machetornis rixosa.

With an obvious hint of disapproval, the HBW remarks that for this species, the “nest [is] a small or bulky but always untidy pad” I suspect the author of these lines lives with teenage children and uses the description of the magpie-robin to vent some frustration with them. But it is all for science, I hear them say.
