FAMILY PARULIDAE 



29I 



Female and immatures, as adult male, but gray replaced by drab 

 grayish brown, slightly lighter on throat; orbital ring whitish to yel- 

 lowish. 



Measurements. — Males (10 from North America, taken in May), 

 wing 69.5-74.0 (71.8), tail 45.8-50.9 (48.1), oilmen from base 10.6- 

 12.9 (11.9), tarsus 19.6-21.4 (20.9) mm. 



Females (8 from North America, taken in May and June), wing 

 67.0-71.0 (68.5), tail 46.2-49.4 (48.2), culmen from base 11.3-12.3 

 (11.6), tarsus 18.7-21.5 (20.1) mm. 



Migrant from the north. Very rare, apparently only a transient; 

 recorded only from the lowlands of western Bocas del Toro, between 

 late September-late October and late March-early April. The occur- 

 rence of this species in Panama has only been confirmed recently, when 

 3 specimens taken in mist nets were collected at Almirante. A female 

 was taken on October 15, 1963, and an unsexed individual on Septem- 

 ber 30, 1964 (Hicks, Mendez, and Loftin, Condor, 1967, p. 319). The 

 third, a female with the skull ossified, was collected by T. V. Heatley 

 on October 23, 1967; (AMNH no. 801541). The spring reports are 

 based only on sightings (Ridgely, 1976, p. 299). The Connecticut 

 Warbler winters in Venezuela, eastern Colombia, and northern Brazil; 

 the bulk of the population travels to and from North America via the 

 West Indies or across the Caribbean. D. L. Hicks wrote Eisenmann 

 that, in addition to the bird he preserved at Almirante in September 

 1964, he banded and released other individuals identified as this species 

 on September 28 and 29 and October 3, and in the following spring on 

 March 21, 22, 28, and 29, and April 4, 5, and 9, 1965.
