in to fall almost at my feet so great was its momentum. Raul, my 

 companion, said that they nested on a nearby rock cliff. Others were 

 seen near Alotenango at 3,200 feet on November 29 and 30. 



The bird taken, a male, is in partial molt. It has a wing measure- 

 ment of 207 mm. and the forehead lighter than the crown, the size and 

 the color mentioned being characteristic of the race mexicana.

On November 29 near Las Lajas below Alotenango flocks of these 

 swifts circled during the entire forenoon, sometimes high overhead, 

 above the soaring zopilotes, and sometimes at a tantalizing distance 

 barely beyond shotgun range. As I returned at noon I saw them lower 

 down above some open fields at 3,900 feet and stopped my auto to 

 watch. The first one that I shot fell far distant and was lost, but the 

 next bird I secured. 



This is a female with a wing measurement of 194 mm. The fore- 

 head and crown are uniform sooty black, the size and this color indi- 

 cating clearly the more southern form, here recorded for the first time 

 from Guatemala, where it is probably to be regarded as a migrant 

 wanderer. Van Rossem ^ has reported a similar bird from Mount 

 Cacaguatique, El Salvador, taken on November 21, 1925.

The only specimen taken is an adult male shot near Panajachel 

 November 14 as it fed at flowers in a dense thicket. The flexible tail 

 was often thrown up at a right angle with the back, as was noted 

 also in the long-tailed males of Tilmafura, a custom that serves to 

 protect these feathers and allow access to flowers deep-set amid twigs 

 and leaves.

At Panajachel on November 12 I found two pairs in a coffee finca 

 near the lake shore and collected a male. The females rested on open 

 twigs while the males poised in the air 5 or 6 inches distant, opening 

 and closing the long fork in the tail, scissors fashion, while the light
