The resplendent quetzal was first described by Mexican naturalist Pablo de La Llave in 1832. [4] It is one of five species of the genus Pharomachrus, commonly known as quetzals. [5] Quetzal is usually specifically used to refer to the resplendent, but it typically applies to all members of the genera Pharomachrus and Euptilotis.
Quetzalcoatlus (/ k ɛ t s əl k oʊ ˈ æ t l ə s /) is a genus of azhdarchid pterosaur that lived during the Maastrichtian age of the Late Cretaceous in North America. The type specimen, recovered in 1971 from the Javelina Formation of Texas, United States, consists of several wing fragments and was described as Quetzalcoatlus northropi in 1975 by Douglas Lawson.
None of the many quetzal species are under immediate threat in the wild, although the eared and resplendent quetzal are at the Near Threatened status. [7] Pharomachrus mocinno is dependent on standing dead and mature trees for breeding holes, which are only formed in primary cloud forest; the species' breeding behavior is linked to the long term existence of these forests such as the few ...
For comparison, the wandering albatross has the largest wingspan of living birds at up to 3.5 m (11 ft) but usually weighs less than 12 kilograms (26 lb). This indicates that the largest pterosaurs may have had higher wing loadings than modern birds (depending on wing profile ) and this has implications for the manner in which pterosaur flight ...
Size comparison of Hatzegopteryx (red) with Pelagornis sandersi (orange) and royal albatross (green). The size of Hatzegopteryx was initially estimated by comparing the 236 mm (9.3 in) humerus fragment with that of Quetzalcoatlus northropi, which has a 544 mm (21.4 in)-long humerus.
A fast-spreading wildfire that erupted this week northwest of Los Angeles roared from nothing to nearly 10,000 acres − in a matter of hours.
Similar in size and shape to the Airmega 200M, the $50 cheaper Airmega Mighty AP-1512HH features a funkier circular design in the front instead of a grill – resembling a giant iPod mini, ...
Trogons range in size from the 23 cm (9.1 in), 40 g (1.4 oz) scarlet-rumped trogon to the 40 cm (16 in), 210 g (7.4 oz) resplendent quetzal (not including the male quetzal's 3-foot-long (0.91 m) tail streamers). Their legs and feet are weak and short, and trogons are essentially unable to walk beyond a very occasional shuffle along a branch.
