approached, the male of the nesting pair attacked it fiercely, 

 driving it off. When the young birds, three in number, finally 

 left the nest, they were guarded carefully by the two parents, 

 who watched them assiduously and did not permit the approach 

 of any other bird. Later another pair, accompanied by two 

 youngsters, was seen catching insects in some long grass. 

 Whether or not this is the usual nesting habit of Crotophaga 

 sulcirostris in Costa Rica I cannot say, but these birds, at least, 

 were paired in orthodox bird fashion. 



, Campephilus guatemalensis guatemalensis (Hartl.). 

 Guatemalan Ivory-Billed Woodpecker. 



A young bird of this species, apparently about three weeks 

 old, was collected on May 5th. It was able to fly but was quite 

 fearless and was caught with no diflftculty. The nest was not 

 seen. 



Synallaxis puclica nigrifumosa (Lawr.). SooTY Synallaxis. 



This little Oven-bird is one of the most characteristic spe- 

 cies about Guapiles. Wherever there is thick, tangled under- 

 growth along streams or in the potreros, its harsh, rail-like notes 

 are certain to be heard. Many characteristic nests were found. 

 They are usually from two to six feet from the ground in a 

 clump of bushes. The entire structure is of course sticks, the 

 nest being about a foot in length and somewhat less in diameter. 

 It is domed at the top, with a long entrance tunnel, the lumen 

 being only sufficiently large for the passage of the bird. On 

 April 5th a nest containing two bluish eggs was found, and on 

 April 19th, we saw an adult pair accompanied by two full-fledged 

 young. 



Carpodectes nitidiis Salvin. Snowy Cotinga. 



This beautiful bird is so rare that even a sight of it is an 

 exciting experience. The species was observed on three separ- 

 ate occasions, but always high in the trees. We first saw two 

 white males and a single female flying about the tops of some 

 forest giants in a bit of pasture jungle about a mile south of
