Vo1 ' lbf™ 1 ] Griscom, Winter Birds of San Antonio, Texas. 51 



Medina Lake. Attwater calls all the ducks migrants, and Lacey calls 

 them all winter residents, either occasional or not uncommon. 



4. Mareca americana. Baldpate. — A drake on Medina Lake with 

 Mallards December 30. According to Attwater a migrant, according to 

 Lacey not uncommon in winter. 



5. Nettion carolinense. Green-winged Teal. — The scarcest of the 

 Anatinee on Medina Lake. 



6. Spatula clypeata. Shoveller. Flock of six December 30 on 

 Medina Lake. 



7. Dafila acuta. Pintail. — The commonest of the Anatinae and the 

 tamest. A stray bird seen January 13 on the San Antonio River south of 

 the city at Hot Wells 



8. Marila americana. Redhead. — Common on Medina Lake. It 

 is not recorded by Lacey, and Attwater calls it a migrant. 



9. Marila valisineria. Canvasback. — In slightly greater numbers 

 than the Redhead. Not recorded by Lacey. Attwater gives it as less 

 common as a migrant than the last. 



10. Marila affinis. Lesser Scaup. — One drake seen January 6. 

 A rare migrant (Attwater); not uncommon in winter (Lacey). 



11. Marila collaris. Ring-necked Duck. — The commonest and 

 tamest duck on Medina Lake. Not recorded by Lacey; a tolerably 

 common migrant (Attwater). 



12. Clangula clangula americana. Whistler. — This is one of the 

 species the occurrence of which is probably due to the severe cold weather. 

 Three drakes seen on January 6, at the extreme upper end of Medina Lake. 

 Previously unrecorded. 



13. Ardea herodias subsp. ? Great Blue Heron. One or two seen 

 on each visit to the Dam. Not previously recorded in winter. 



14. Fulica americana. Coot. Very abundant on Medina Lake. 

 Not mentioned previously as occurring in winter. 



15. Oxyechus vociferus. Killdeer. A few birds in all types of 

 country, their numbers apparently unaffected by the severe weather. 



16. Zenaidura macroura carolinensis. Mourning Dove. — A few 

 birds all winter. 



17. Scardafella inca. Inca Dove. — Not uncommon on the outskirts 

 of San Antonio right through the winter. Attwater regarded it as very 

 rare, giving only one record. All later writers agree in its being a common 

 resident, so it must have extended its range northward. As it is extra- 

 ordinarily tame and confiding, and a dooryard bird, it seems improbable 

 that Attwater could have overlooked it. 



18. Cathartes aura septentrionalis. Turkey Vulture. — De- 

 cidedly rare. A few birds seen in the city of San Antonio, and none after 

 the cold wave of January 10. 



19. Catharista urubu. Black Vulture. — Decidedly uncommon, 

 except at Medina Lake, where it was quite plentiful.
