 third week in May.

26. Pyranga ludoviciana ( Wils.). No females were recognized, but 

 the males were rather common from May 15 to June 1. A mile or so up 

 the Fountain was a place where the offal from a neighboring slaughter- 

 house was dumped, and the Tanagers, in company with Bullock's Oriole

 force, feeding on the swarms of insects attracted by the odoriferous 

 deposit.

 dant species to be found here.
