In his original description Lesson gave Brazil as the habitat of this species}, but 
afterwards mentioned Jalapa in Mexico as its domicile, on the authority of Delattre 2. 
Examples from Eastern Mexico have, as a rule, more deeply forked tails than those 
from Guatemala and places still further south, but we are unable to distinguish any 
definite races of this bird. Guatemalan examples have rather less grey on the tips of 
the central rectrices, but this is an eminently variable character, though always present 
in fully adult birds. Some specimens have these feathers tipped with green, which is 
probably a character of immaturity or perhaps only observable in perfectly freshly- 
moulted feathers. One Duefias specimen before us has the left central rectrix tipped 
with green, whilst the right one is plain. 
Guatemalan specimens were described by Gould as C. osberti ‘4, and Costa Rican 
ones by Cabanis as C. salvini?°. These last have the tail still less deeply forked, but 
in view of the apparently continuous range of the species we doubt the possibility of 
recognizing any really definite races. We note, however, that the specimens from the 
islands of Ruatan and Bonacca have the outer rectrices unusually wide. 
C. canivett was a very familiar species with us during our various visits to the 
Hacienda at Duefias, and specimens could generally be seen in the garden adjoining 
the house searching the plants in bloom for their insect food. At San Juan del Sur, in 
Nicaragua, Salvin noticed it in May in some numbers feeding from the flowers of the 
tamarind-trees which line the shore of the bay.
