Product Information

A 1996 study of the mitochondrial DNA of the potoos supported the monophyly of the family although it did not support the previous assumption that it was closely related to the oilbirds. [5] The study also found a great deal of genetic divergence between the species, suggesting that these species are themselves very old. The level of divergence is the highest of any genus of birds, being more typical of the divergence between genera or even families. This raises the possibility that there are several cryptic species to be discovered. For example, the northern potoo was for a long time considered to be the same species as the common potoo, but the two species have now been separated on the basis of their calls. In spite of this there is no morphological way to separate the two species. [6] Lost and grieving their mother’s death, twins Ana and Nan plan their revenge against the man they believe is responsible: the literary critic Eben. Trapped within the National Library of Wales, Ana and Nan have Eben exactly where they want him, until the plan starts to go awry. PS.

Ghostbird by Carol Lovekin (2016)

The English zoologist Hugh Cott, describing Nyctibius griseus as "this wonderful bird", writes that it "habitually selects the top of an upright stump as a receptacle for its egg, which usually occupies a small hollow just, and only just, large enough to contain it ... the stump selected had thrown up a new leader just below the point of fracture ... and the birds sat facing this in such a way that when viewed from behind they came into line and blended with the grey stem." [18] Food and feeding [ edit ] Their wide mouths are their greatest asset; they essentially use them as nets for grabbing their prey with a single snap.

The eyes are large, even larger than those of nightjars. As in many species of nocturnal birds, they reflect the light of flashlights. [14] Their eyes, which could be conspicuous to potential predators during the day, have unusual slits in the lids, [15] which allow potoos to sense movement even when their eyes are closed. Their plumage is cryptic, helping them blend into the branches on which they spend their days. Sang Sorenson has just turned 16 years old. Her family resides in a small town in Illinois. Her father is frequently gone on longer and longer work trips. Sang's mother is declining rapidly from an unknown to Sang illness. You can’t! They look identical. This is actually a source of frustration for ornithologists since it’s hard to determine which gender is hunting, nesting or courting the other. However, these strange-looking birds have a lot more going on than their looks might suggest! Get all the facts here: 1. Is the potoo bird real?A serious push has been under way in Congress for some time to revise the Endangered Species Act (eviscerate it, conservationists say), and some worry that the ivorybill episode could give ammunition to politicians and pundits who might claim that environmentalists overreact, abuse and manipulate science, and use scare tactics to achieve their goals. I asked if the town had considered what would happen if the ivorybill was never seen again. Katie laughed and said, “That question was being asked long before now.” In addition, the fossil genus Paraprefica, the only member of the extinct subfamily Parapreficinae, is known from the Eocene of Germany (the Messel pit), marking the earliest fossil evidence of potoos. The fossil genus Euronyctibius, from the Oligocene of France, was formerly considered a potoo, but analysis supports it instead being a close relative of the oilbird (family Steatornithidae).
