To an intermediate-level birder like me, the material in Better Birding –highly focused, detailed, based on the latest research and years of field experience– is daunting, but also fascinating. Mentorship is an essential part of the birding experience, and it needs to be encouraged. Just go to the boldfaced page number.
This would have allowed you to summarize your experience in sentences such as “A total of 98 boluses regurgitated by 52 chicks aged 1 day to 11 days after hatching form the sample and are shown to contain 323 food items.” This Cattle Egret has just read a paper stating that it would be 3.6
Of course, Tiaozini also has Cattle Egret … … and the usually somewhat depressed looking Black-crowned Night Heron. A juvenile night heron experimented with getting across fences (note: neither fence nor heron were hurt during the experiment). Also available as a set of two.

Such an intimate encounter with one of the world’s rarest birds was a memorable experience.
” I have a scientific background myself, and I guess some experiments on animals may sometimes be justifiable, but others just leave me disgusted, such as this one. But it is all for science, I hear them say. Swinhoe’s White-eye was just promoted to the rank of a full species in 2018. but they do.
