In the non-breeding season, male Baya Weavers sometimes enter the basket-making trade, often with considerable success. Meanwhile, the females seem to have a much more relaxing life, at least in this early stage of the breeding season. You can see why here. Trust me, the species name makes sense for the male, though not for the female.

Data were collected from the North American Breeding Bird Survey and the Pan-European Common Birds Monitoring Scheme. The trend in CII is positive and similar in the two regions. On both continents, interspecific and spatial variation in population abundance trends are well predicted by climate suitability trends.

Not all habitat change is due to humans; there is Chestnut Blight destroying American Chestnuts in the early 1900s, and the more recent Dutch Elm disease. The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience.

It seems the ones I got decent photos of are all juveniles – it generally seems to be easier to get photos of juveniles as they have not quite learned to avoid humans. Thank god that this does not apply to humans. Sometimes being a member of the human race feels very embarrassing.

I visited Tengchong in late 2020 and wrote about it – but I also went there earlier, in 2017, and this post shows some photos I took during that trip, along with the usual comments that seem to be much more about ridiculing my fellow humans (especially ornithologists and the like) than providing useful information on birds.

It contains numerous citations to the literature, as the process must be based on the best available science. In particular, a captive-breeding program (1960-2011) likely saved the species from imminent extinction (2,800 were released) and expanded the range of the species to islands where they had been extirpated.

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.
