I’m sure many of you have had similar experiences. I’m wondering as I write if you are shaking your head, uneasy that all these FACTS will interfere with your love of observing owls, an experience that easily borders on the mystical for some of us. But what do we know beyond these commonly seen and heard behaviors?

Experiments in the field (the famed Asa Wright Nature Center veranda) involving Bananaquits and bananas came up with numbers ranging from 7 to 16, but a tanager always came along to interfere with Bananaquits’ noisy appreciation of their namesake fruit.

Gorman’s personal field experience informs much of the text and his total grasp of the field means he relates one research finding to another with narrative ease. I do wish that Gorman included more of his personal experiences and stories in the natural history tradition of ornithologists like Alexander Skutch.

So sorry, but this is a necessary part of our thought experiment!) Let’s do another thought experiment. First, I set the dial to produce the kind of high energy radioactive radiation stuff that would be emitted by an atomic bomb, and calibrate it to dose you (sorry, but this is necessary for our thought experiment!)

Illustrations were created using diverse visual and physical source materials–skin collections from Australian museums and a database of over 300,000 photographs (plus, of course, the artists’ years of field experience). Some offer nest information, egg information, breeding timeline, in flight views, etc.

I know from experience how accessible Dennis is, last year he helped me identify a damselfly I photographed in Costa Rica (Argia anceps, no common name). 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.

Indeed, most cuckoo eggs are accepted by the babax ( source ), although a small proportion of hosts reject cuckoo eggs and often boast about this capability when having a few too many drinks. Some Chinese Babax waste part of their lives feeding chicks of Large Hawk Cuckoos, which parasitize the babax species.
