Using ministerial connections he obtained 100 mallard eggs from the US and began to breed and distribute them. A PhD student was presenting her research into the population in Westland, the relic population of Grey Duck. Female Mallard, photo by Corey. There the matter may have remained, but for a gentleman named Cecil Whitney.

For birders, it’s the extremely large book, shelved in a place where it can’t crush the field guides, used to research the history of a bird in their area. A breeding bird atlas is a special kind of book. Corey did just this in this 2011 posting about Vesper Sparrow Pooecetes gramineus in New York State.

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.” Women who like jacanas will probably also like Spotted Redshanks. But maybe that is actually a good thing.

Read what you want about the origin of domestic cats; the genetic evidence is not properly sampled. The majority of wildcats live today in Africa, and virtually none of them have provided the DNA from which supposed histories of domestication have been constructed by researchers.

I queried for birds and mammals living in the new world (but excluding sea birds) outside of the tropics (which includes a lot of tropical migratory birds, obviously) an a similar sample of mammals. This is not a surprise.

Fortunately, Clare graciously send me examples of pages and plates from her field guide collection, using kingfisher as the sample bird. Some offer nest information, egg information, breeding timeline, in flight views, etc. She comments, “Each field guide we have differs in information & we have all of the guides available.

Which actually, is hardly surprising, based on my tiny sample size. I can’t help wondering if the conspicuousness of the bird I saw was an attempt to draw attention to itself to distract the Grey Warbler while the other laid her eggs. That said, it was just such a silly impulse that took me last weekend. In the open!
