_Geographic range._--Formosa. In Micronesia: Mariana Islands--Rota

(introduced).

_Specimens examined._--Total number, 7 (4 males, 3 females), from

Mariana Islands, USNM--Rota (Oct. 18, 19, Nov. 2).

_Remarks._--This drongo was introduced from Formosa to Rota by the

Japanese South Seas Development Company (Nanyo Kohatsu Kabushiki Kaisha)

apparently in 1935. An illustrated booklet, printed by this organization

and seen by members of the NAMRU2 party at the Rota Civil Government

headquarters, showed pictures of the captive birds before release and

indicated that they had been brought to Rota for the purpose of

controlling destructive insects. Dr. Charles Vaurie has examined these

birds and compared them with a series of drongos from Formosa in the

collection of the American Museum of Natural History.

The drongo appears well adapted at Rota, where it prefers cultivated

areas and the bombed village sites to thick woodlands. Birds were found

in small flocks often perched in large shade trees in village areas.

Weights of two immature males are 53 and 61 grams. One adult male

measures: wing, 144, tail, 153, culmen, 26, tarsus, 22.
