and females act in this way and often when no other bird is 
near. Once this morning I saw a male Jacobin showing off 
before his mate. Both were rather high in air (50 or 60 
feet) over the clearing, but not far from the bois 
immortel grove. The female was flitting about and poising, 
perhaps catching small insects. The male Y/ould rise about 
20 feet above her and, darting down, sweep just over her 
back, then rise and plunge again, describing very nearly 
the swing of a pendulum. All the while he kept his tail 
spread to its fullest extent, showing the white very con¬ 
spicuously, The white on the nape wa.s also displayed to 
remarkable advantage, flashing in the sunlight whenever the 
bird turned it tovirards me, I am beginning to learn the 
notes of the Hummers here. Eucephala and Glaucis made a 
shrill Fringiline zeep , Florisuga mellivor^ and Agyrtria 
chinopretus — a soft, full [^suq^ very like the chirp of a 
Warbler. 
Early in the morning I shot a female Bell Bird in 
a bois immortel which stands within a few yards of our 
ajouba and late in the afternoon a fine male White-headed 
Manakin in a thicket not ten yards from our work bench. 
The Manakin made his sharp whirring several times as Chapman 
and I stood watching him.
