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.

I enjoy collecting children’s books about birds and nature that I come across in the expected (book stores) and unexpected (academic library conference reports) places. The targeted age group is 6 to 11 years. Spanish settlers arrived in 1493 and called the birds Coterras. Other Europeans came. It really isn’t.

The proprietor of our ecolodge guides my small group of birders up a steep slope where we see, just at the point where a scope view deteriorates into pixels, a huge bird—a Chaco Eagle, also known as a Crowned Eagle—on a huge nest. September 2017, Cerrado, Brazil. We are cautioned to keep the location of the eagle a secret.

When not climbing, he collected species, and thus a number of birds are named after him. Interestingly, only about half of the helpers are related to the breeding pair … … and only the ones not related to the pair gained some parentage, either by sneaking in some sex with the breeding female or by adding an egg.

Once the egg has been laid, the female is chased away and the males hatch it.” Other research (cited on the rather straightforwardly named website www.genderinclusivebiology.com) found that 80% of gay swan couples successfully fledge their young, compared with only 30% for straight couples. So will the Red-flanked Bluetail.

Here’s some data from the famous research project of Manu, Peru, giving biomass in kilograms per hectare. This is also a hard question to address because most data on animal size distribution does not compare across classes of animals, and/or focuses on groups that would not be helpful.

This is the story of Fox’s experiences on board the Achiever, the research vessel of the Raincoast Conservation Foundation. The Achiever’s survey voyages took place from 2005 to 2008; the goal was to collect baseline data on sea mammals and marine birds. Northern Fulmar, image courtesy of Peter Hodum.

Scientific names have been reviewed by the Working Group on Avian Nomenclature of the International Ornithologists’ Union. Within each group, birds in the same family are grouped together and birds in the same genus “usually occur consecutively.” So, there are two basic sections–marine and freshwater birds (pp.

This may have been partly a leftover from the Victorian fascination with egg collecting (the infamous passion known as oology), but probably more from people’s burgeoning interest in the nests and eggs found in their gardens and fields, gateway artifacts to a newer hobby called birdwatching.

Family and genus sections all begin with descriptions of what features the group has in common and how individuals differ. Common and differing traits will include type of coloring, thorax patterning, how they perch or fly, how they copulate, and how they oviposit, lay eggs. With odonates, there are always exceptions!

If the male’s color fades after the first egg, the female reacts by laying a smaller second egg – seemingly deciding that it is better to cut her losses as the male apparently is the avian equivalent of a deadbeat father. Are these the paper mills one occasionally reads about in relation to Chinese research papers?

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.
