One of the most contentious issues among scientists who study the evolution of birds is identifying precisely when the modern birds (Neornithes) first appeared. This is due to conflicts between the fossil record and molecular dating methodologies. For example,…

tetrapodzoology | December 23, 2008
Welcome to my final set of musing and recollections about our recent Moroccan trip, led by Nizar Ibrahim. Mostly I'll be talking here about the amazing desert birds we got to see, but I also have stuff to say about the mammals, and - of course - about the fossils...
One of the birds I most wanted to see - in fact it was top of my list - was the remarkable Greater hoopoe lark Alaemon alaudipes [see photo at top here for Richard's photo of one of these birds], and eventually we were to see four or five of these (though never more than one at the same time). Alaemon occurs across Africa and is…

tetrapodzoology | December 20, 2008
More musings from the Morocco trip. So, we travelled over the Atlas Mountains and were soon up at the snowline. We joked about seeing lions and bears, but did see a Barbary partridge Alectoris barbara (another first) and a representative of the strikingly blue Blue tit subspecies Cyanistes caeruleus ultramarinus. If you've been keeping up with parid taxonomy you'll know that some workers now regard this blue tit of north-west Africa and the Canaries as a distinct species, the Ultramarine or Afrocanarian tit C. ultramarinus (but note that not all the blue tits of the Canaries belong to this…

tetrapodzoology | December 19, 2008
Several weeks ago, I and a group of colleagues from the University of Portsmouth (Dave Martill, Robert Loveridge and Richard Hing) set off on a trip to the Cretaceous exposures of Morocco. We were to be joined by Nizar Ibrahim from University College Dublin - our team leader - and by Samir Zouhri and Lahssen Baidder from the University of Casablanca. Our primary aim was to discover Cretaceous dinosaurs, pterosaurs and other fossil reptiles, but we were also interested in studying the region's geology, and to learn about the sedimentology, palaeoenvironment and taphonomic setting of the rocks…

of Mongolia by the American Museum of Natural History.
Image: Mick Ellison, American Museum of Natural History.
Oviraptors ("egg seizer") were given their name because their fossil remains were first discovered on top of a pile of eggs. Because of their close proximity to clutches of dinosaur eggs, it was initially assumed that these dinosaurs were eating them. However, in his 1924 paper, their…

Two nectar-feeding birds from Hawai'i, the kioea (brown-streaked, in middle) and an o'o species (lower left), looked so much like nectar specialists from the western Pacific (two species on right) that taxonomists put them all in the same honeyeater family, the Meliphagidae. All the Hawaiian birds are unfortunately extinct, but DNA evidence shows that their resemblance resulted from convergent evolution, because the Hawaiian birds were actually much…

tetrapodzoology | December 15, 2008I like ducks, and I particularly like steamer ducks. Again, here we revisit some Tet Zoo ver 1 text that was originally published in 2006 as part of the Ten Birds Meme.
The most widely distributed of the four Tachyeres species*, the Flying steamer duck T. patachonicus inhabits both the fresh and marine waters of the Falklands and southern Patagonia and Tierra del Fuego. While all other steamer-ducks are flightless, T. patachonicus is (obviously) not, and in contrast to its flightless relatives it has proportionally bigger pectoral muscles and lower wing loadings. But what makes the species…
