=_Dichromanassa rufescens rufescens_= (Gmelin): Reddish Egret.--This egret was recorded only about the inlet at Camp 2, where 15 individuals were feeding, either singly or in small groups, on July 8 and 9. We noted frequent use of the "Open Wing" method of foraging, as described by Meyerriecks (1960:108). Specimen: [F] juv., 38899, ovary inactive, 587 gm., Camp 2, July 8. This specimen is referable to the nominate subspecies, which is resident along the Gulf coast. Our record seems to be the first for the species in Tamaulipas. =_Leucophoyx thula_= (Molina): Snowy Egret.--Ten individuals of this species were feeding in association with Reddish Egrets in the inlet at Camp 2 on July 9. =_Hydranassa tricolor_= (P. L. S. Müller): Tricolored Heron.--An observation of one individual flying along the margin of the laguna near Camp 2 is our only record of this species. =_Nycticorax nycticorax_= (Linnaeus): Black-crowned Night Heron.--This heron was found only at the edge of the laguna near Camp 2; ten individuals were noted on July 8, and 20 were seen perched in a clump of mesquite trees on July 9. Perhaps half the birds seen were in juvenal plumage. A juvenile was shot and examined on July 9 but was not preserved as a specimen. There appears to be no definite evidence of breeding by this species in Tamaulipas (Mexican Check-list, 1950:32), but such may be expected because the species breeds locally in Texas (Peterson, 1960:19) and in Veracruz. =_Ajaia ajaja_= (Linnaeus): Roseate Spoonbill.--On July 9 at Camp 2, 38 spoonbills flew up from the edge of the laguna where they had been resting near a large flock of white pelicans. =_Cathartes aura_= (Linnaeus): Turkey Vulture.--One Turkey Vulture was seen flying east at a point 2 miles west of Washington Beach on July 10. It is noteworthy that we saw no Yellow-headed Vultures (_C. burrovianus_), a species recently recorded in the region of Tampico north to Lomas del Real (Graber and Graber, 1954_a_). =_Colinus virginianus texanus_= (Lawrence): Bob-white.--This species was seen only in or near clumps of mesquite near Camp 1, where three covies (7, 13, and 18 individuals) were flushed on July 7. Specimen: [M] juv., 38900, testis 3 mm., 100 gm., 6 P old, Camp 1, July 7. =_Porzana carolina_= (Linnaeus): Sora Rail.--On sand flats at Camp 1 we found a left humerus and several other post-cranial skeletal elements that have been identified by Dr. Pierce Brodkorb as belonging to this species. All the bones are of Recent age. We have no other record of the Sora Rail on the barrier island, but in all probability it occurs as a migrant and winter visitant along margins of the laguna.
