As it walks in its marshy habitat, its ungainly stride makes it look as if the bird is limping, hence the common name of Limpkin. Aramus, the genus name, comes from the Greek meaning sword and the species name guarauna from a Tupi (Brazilian) language and meaning marsh bird. And indeed the Limpkin is a …
Attractive birds of the tropics of Asia, Africa, South America, and Australia, Jacanas sprightly move over the tops of lily pads and other floating vegetation with ease. They are weak fliers and go aerial for only short distances, but they can swim underwater to avoid predators and remain in the water for long periods with …
The order Caprimulgiformes includes four families of birds with not only odd appearances but odd names. Commonly called nightjars, the order is comprised of about 120 species of soft-plumaged and cryptically colored birds including nighthawks, potoos, frogmouths, poorwills, owlet-frogmouths and oilbirds. Resembling strange owls, nightjars lack the talons and strong beak; in fact their feet …
You may have marveled at the spectacular and elegant control albatrosses have over their above ocean flights. You may be familiar with dynamic soaring, the method albatrosses use to remain aloft over the ocean for days, covering as much as 3000 miles a week, as measured by bird-borne video flight loggers. Feeding at sea, young …
There are numerous bird blogs and websites on the internet and I presume my readers read and subscribe to others as well. Most bird blogs are well- written, researched, and informative. But occasionally I run across a real loser, whether badly written, full of inaccurate information, or just trivially stupid. BirdwatchingUSA fits all of those …
Years ago, some well-meaning bird lover passed away and left a pretty decent bundle of money to our local Audubon Society, but she stipulated that the funds are only to be used to benefit songbirds, not hawks. Now I’m not quite sure how one does that. If you improve the habitat for songbirds, you inadvertently …
There has always been the presumption or assumption that tropical birds are generally more colorful than those further from the tropics. The closer the birds live to the equator, the more colorful they are, we have always thought. Alexander von Humboldt, Charles Darwin, and Alfred Russell Wallace, well-known naturalists of the 19th century, all noted …
There is a “rule,” actually a rule of thumb, that says as distance from the equator increases (like going farther north in the northern hemisphere) the body sizes of warm-blooded animals tend to change, the surface area of the body becoming proportionately less than the volume – the surface area shrinks as volume increases. Biologically …
In the fall of 2021 the U.S. Fish and Wildlife Service declared the Ivory-billed Woodpecker extinct as there have been no reliable sightings of the bird since 1944. But individuals and groups have occasionally asserted that they have seen an individual or two deep down in the forests of Louisiana. The latest declaration is from …
I previously wrote a post explaining why birds don’t fall out of trees while they are sleeping. Not falling out of a tree has to do with the arrangement of muscles and tendons on the lower legs, but this explanation mainly applies to those birds in the Order Passeriformes, the Perching Birds. But not to …
