FAMILY ALCEDINIDAE 433 



light orange-buff, partially joined in a narrow broken collar on hind- 

 neck; rest of under surface rufous to deep orange-rufous, with the 

 feathers white basally ; under wing coverts and axillars cinnamon ; 

 under surface of primaries spotted broadly with white; tibia dull 

 greenish black. 



Adult female, like male, but with scanty to very few flecks of 

 white to buffy white on wing coverts, rump and upper tail coverts ; 

 upper breast banded widely with black, with the feathers tipped 

 rather broadly with white to buffy white. 



Immature, like female, but somewhat more heavily spotted on 

 lower back and wings ; males with a narrow black breastband, much 

 broken by rufous spotting and tipping. 



A female, taken at Armila, San Bias, February 28, 1963, had 

 the iris brown ; base of gonys and lower margin of mandibular rami 

 dull white; rest of bill black; crus, tarsus, and toes dark brownish 

 neutral gray ; claws black. 



Measurements. — Males (10 from Panama and Choco, Colombia), 

 wing 90.0-96.9 (93.7), tail 58.0-63.0 (60.1), culmen from base 49.9- 

 56.1 (52.8), tarsus 9.8-11.6 (11.0) mm. 



Females (14 from Panama), wing 92.6-98.7 (95.8), tail 57.5- 

 64.7 (61.8), culmen from base 49.0-55.0 (52.1), tarsus 10.2-11.3 

 (10.8) mm. 



Resident. Found locally in the lowlands on the Caribbean slope 

 from Bocas del Toro through San Bias; on the Pacific side from 

 eastern Province of Panama (mouth of Rio Chico) east through 

 Darien. Locally in the Archipielago de las Perlas (islas Viveros, 

 Del Rey, Cafias). 



The only report on the Pacific slope west of the Canal Zone is 

 1 for "Veraguas (Arce)" listed by Salvin and Godman (Biol. Centr.- 

 Amer., Aves, vol. 2, 1895, p. 478). The specimen so labeled, but 

 without other data, is in the British Museum in London. As it is 

 not listed by Salvin in any of his earlier reports of Arce's collections 

 it seems probable that the locality is wrongly marked and that the 

 bird was taken somewhere near the lower Chagres in what is now 

 the Canal Zone. 



Because of their secretive habits usually these small kingfishers 

 are more abundant than is indicated by the relatively few occasions 

 on which they are seen. During my field excursions, in careful 

 search I have found them fairly common in the extensive mangrove 

 swamps around Bahia Almirante in Bocas del Toro, and along 

 heavily forested shores on the Rio Chiman, the Rio Chucunaque,
