WILSONIA CANADENSIS (Linnaeus) : Canada Warbler 



Muscicapa canadensis Linnaeus, Systema naturae, ed. 12, vol. 1, 1776, p. 327 

 (Canada). 



Carriker shot one on the higher slopes of Volcan San Martin on 

 April 16, 1940, and another on Cerro de Tuxtla, May 7. Both are 

 males. 



SETOPHAGA RUTICILLA (Linnaeus) : American Redstart 



MotaciUa Ruticttla Linnaeus, Systema naturae, ed. 10, vol. 1, 175S, p. 186 

 (Virginia). 



The redstart was fairly common near Tres Zapotes, where Carri- 

 ker shot one on January 27, 1940, indicating its presence through the 

 winter. In 1939, through March and until April 10, 1 recorded the 

 species nearly every day. Carriker saw it in the Sierra de Tuxtla 

 up to 2,000 feet elevation. In one adult male taken the wing spot is 

 small, while in two others it is decidedly more extensive, illustrating 

 the usual variation in this regard. 



Redstarts came regularly to small trees in the little clearing in 

 which stood the houses of our camp, so that I noted them constantly 

 from the porch under which I prepared my specimens. On March 

 19 and 20 one female, marked by ragged feathering, ranged within a 

 space 35 feet long by 20 feet wide around a small group of shrubs 

 ond little trees at the border of the clearing mentioned. Once I saw 

 it fly across to another clump of trees to join a flock of passing mi- 

 grants made up of parula and magnolia warblers, but soon it was 

 back, going over and over its selected area in search for insects. The 

 very limited space that it chose was remarkable, especially since to 

 my eye there was nothing to single out the few square feet of terri- 

 tory that it selected from miles of similar country on all sides. It 

 seemed an indication of rather sedentary habit on the part of one 

 of our birds from the north when in its winter home. 



MYIOBORUS MINIATUS MOLOCHINUS Wetmore 



Myioborus miniatus molochinus Wetmore, Proc. Biol. Soe. Washington, vol. 55, 

 Aug. 13, 1942, p. 105 (between 3,000 and 4,000 feet elevation on Volcan San 

 Martin, Sierra de Tuxtla, Veracruz, Mexico). 



Carriker found this bird above 2,500 feet elevation on Volcan San 

 Martin but did not record it on the Cerro de Tuxtla. It was active 

 and conspicuous in the taller undergrowth and smaller trees of the 

 forest. Male and female were taken on April 16 and other males on 

 April 17 and 23. 



When compared with Myioborus m. miniatus (Swainson), which is 

 found in the main mountain ranges to the west and northwest, molo- 

 chinus differs in the darker dorsal surface, including the wings and the 

 sides of the head and neck, the brighter brown crown patch, the
