14 TRE AU Dr's @.NetB Ce esigiens 
FRANKLIN’S GULL (Larus pipixcan). Two observed in winter 
plumage June 13 on coastal prairies.’ 
GULL-BILLED TERN (Gelochelidon nilotica aranea). June 13 on 
coastal lagoon and June 15 near Horsehead. 
FORSTER’S TERN (Sterna forsteri). June 12, one pair at the city 
lake of Harlingen; several noted on the coastal prairies on June 13. 
GOLDEN-FRONTED WOODPECKER (Centurus aurifrons). Common. 
TEXAS WOODPECKER (Dryobates scalaris symplectus). Common. 
CoucH’s KINGBIRD (Tyrannus melancholicus). Rather common; 
one pair also observed at Laredo, June 8. 
SCISSOR-TAILED FLYCATCHER (Muscivora forficata). Though seen 
in every locality visited, only a few were noted. 
DERBY FLYCATCHER (Pitangus sulphuratus derbianus). Several 
observed both at Mission and Harlingen. Nest seen June 13 at 
Olmito, built in Spanish moss (which, incidentally, favors very highly 
the one species of elm in the Valley, Ulmus crassifolia). The nest 
was perfectly hidden and could be located only by the entrance hole. 
It was high and inaccessible. At the time of our visit (Mr. Davis 
and the writer), the young birds had already left the nest and could 
be heard in the vicinity. 
MEXICAN CRESTED FLYCATCHER (Myiarchus tyrannulus nelsoni). 
Common. 
VERMILION FLYCATCHER (Pyrocephalus rubinus mexicanus). 
Very local in distribution, as far as summer residents are concerned; 
apparently restricted to one colony in the clay dune region of the 
coastal prairies between Brownsville and Boca Chica, where on June 
13 five individuals including two young were observed. Four pairs 
constituted the colony. A nest with three eggs was found. Due to 
the mesquite-chopping activities of a Mexican goat-herder (and per- 
haps to other predators), several nests of these birds were destroyed.+ 
TEXAS HORNED LARK (Otocoris alpestris giraudi). Fairly com- 
mon on the coastal prairies. 
LESSER CLIFF SWALLOW (Petrochelidon albifrons tachina). <A 
colony of 150 observed on June 14 south of LaFeria near the Rio 
Grande and the county line, where they were nesting underneath a 
bridge across an irrigation ditch. 
GREEN JAY (Xanthoura luxuoasa glaucescens). Seen June 10 at 
Mission and June 12 and 13 at Harlingen. 
WHITE-NECKED RAVEN (Corvus cryptoleucus). Noted only at 
Laredo on June 8 and 9. 
BLACK-CRESTED TITMOUSE (Baeolophus atricristatus atricrista- 
tus). Rather common. 
ARIZONA VERDIN (Auriparus flaviceps flaviceps). Noted only at 
Laredo on June 8 and 9. 
TEXAS WREN (Thryomanes bewicki cryptus). Fairly common.
