At the Cocoa Research Station this common bird usually was seen
sitting on a dead branch of a shade tree in the cocoa whence it
would dart out after insects. It rarely perched higher than 12
feet. Occasionally it was seen in a clearing in the primary forest.

_=Hemiprocne longipennis longipennis=_ (Rafinesque): Crested Tree
Swift.--_Specimens_, 2: Cocoa Research Station: [Male] testis 4 x 3 mm.,
September 4, 1962, MCT 2866; sex?, 42.8 gm., September 8, 1962, MCT
2888.

These swifts also were common at the Cocoa Research Station. Unlike
_H. comata_, these birds flew high and sat far up in trees while
resting. I never observed them in the primary forest.

The two specimens were more greenish-blue dorsally than typical _H.
l. longipennis_. Specimens from Java were paler gray ventrally and
their tertials were more nearly white. Too few specimens were
available to permit determination of the constancy of the mentioned
variation and the two from the station are referred to the nominate
subspecies until more material becomes available.

_=Harpactes diardi diardi=_ (Temminck): Diard's Trogon.--_Specimens_, 8:
Cocoa Research Station: [Female], 95.9 gm., July 2, 1962, MCT 2579; 3
alcoholic naked young, July 3, 1962, presumed young of 2579, MCT
2581-83; [Female], 95.0 gm., August 20, 1962, MCT 2782; [Male] testis 6
x 3 mm., September 5, 1962, MCT 2870; [Male], September 5, 1962, MCT
2871; [Male], December 1, 1962, MCT 3409.

This was the most numerous of the trogons at the Cocoa Research
Station. One female was taken in a live trap set for rats in the
cocoa. The next day a laborer found a young, presumably of that
female, in a nest in the same area. On August 20, a flock of 5 to
10 birds was seen moving together in a loose group through the
jungle. This species appeared to be a bird of the primary forest,
but occasionally was found in the cocoa.

_=Harpactes kasumba impavidus=_ (Chasen and Kloss): Red-naped
Trogon.--_Specimens_, 2: Cocoa Research Station: [Male], 72.1 gm.,
August 5, 1962, MCT 3730 (discarded); [Female], September 7, 1962, MCT
2883.

This species of the deep forest was not seen in any other habitat.

_=Harpactes duvauceli=_ (Temminck): Scarlet-rumped Trogon.--_Specimens_,
7: Cocoa Research Station: [Female], 30.9 gm., July 24, 1962, MCT 2648;
[Male]?, December 1, 1962, MCT 3407; [Male], December 1, 196
