    Pygmy Falcon (Polihierax semitorquatus)

    Also known as the African Pygmy Falcon, P. semitorquatus is a small species of falcon, that occurs in eastern and southern Africa. The population in eastern Africa (P. s. castanotus) occurs from Sudan to Somalia south to Uganda and Tanzania. The population in southern Africa (P. s. semitorquatus) occurs from Angola to South Africa.

    True to its common name P. semitorquatus is very small at only 19-20 cm long, making it the smallest raptor in Africa. Pygmy falcons typically inhabit dry bush habitats and will feed on insects, small mammals, birds, and reptiles. Pygmy falcons will usually in the nests of weavers, and even though they feed on bird will rarely go after their weaver neighbors.

    The Townsend’s Warbler (Setophaga townsendi) is one of the more rare migrants passing through the Texas during this spring migration. This beautiful male stopped over on South Padre Island this past weekend.This is usually a more Westerly warbler, and isn’t seen in Texas very often.

    Two New Alligator Snapping Turtle Species Announced, Some Face Localized Risks

    by Brett Smith, Red Orbit

    A new study published in the journal Zootaxa reveals that the alligator snapping turtle is actually three different species – not one as previously thought.The report also indicated that the localized distribution of these species, which includes coastal rivers of the northern Gulf of Mexico, poses a significant threat to their continued survival.

    “We have to be especially careful with our management of the Suwannee River species because this turtle exists only in that river and its tributaries,” said study author Travis Thomas, a Florida Fish and Wildlife Commission scientist, referring to a small river that winds through parts of Georgia and Florida. “If something catastrophic were to occur, such as a chemical spill or something that affects the entire river, it could potentially devastate this species. The turtle is extremely limited by its habitat. All it has is this river and it has nowhere else to go.”

    Based on analyses of the fossil record and modern turtle morphology, study researchers revised the genus Macrochelys to include Macrochelys temminkii and the two newly-described species, Macrochelys apalachicolae and Macrochelys suwanniensis. Constrained to river systems that empty into the northern Gulf of Mexico, the species are split by geography, which triggered changes in genetics, according to the study team…

    Pseudoeurycea bellii is the largest of the lungless salamanders (family Plethodontidae) and one of the largest terrestrial salamanders, with a maximum size of 36 cm in total length. Pseudoeurycea bellii has a stout body, long, muscular limbs, and a long tail, constricted at the base. The tongue is projectile. This salamander has shiny dark black skin with two red to red-orange spots on the occipital area (back of the head) generally present. The subspecies P. b. bellii has a dorsal mark in the shape of a chevron, generally followed by paired rows of red to red-orange spots (sometimes joined into chevrons) running along the back, down to the base of the tail. In contrast, the subspecies P. b. sierraoccidentalis (found in northern Mexico, in an area straddling the border of Sonora and Chihuahua) has greatly reduced reddish coloration, with asymmetric and irregular small dorsal markings (Parra-Olea et al. 2005).
