Pied-billed There are this season, as nearly as we could estimate 
rdr ebe s their numbers to-day, at least six, probably eight or ten, 
and possibly as many as twelve, pairs of Carolina Grebes 
breeding in the reservoir pond. They inhabit every part of 
it and move about a good deal, appearing ana disappearing 
in the spaces of open water;but it seemed to me that each 
pair confined their roving within certain limits. With the 
exception of a female with young, all wexe very shy and sus¬ 
picious, showing themselves in the open water only when all 
was quiet about the pond, and if they caught sight of us on 
shore, sinking quietly beneath the water and seeking the dense 
depths of the thickets of button bushes. When not alarmed 
or apprehensive, they swam about boldly in the open water, 
sometimes approaching within a few yards of the shore and 
diving a great deal for food. At times they floated as 
high out of water as Ducks and looked nearly as large as 
Anas obscura Pllla • The shape and carriage of 
the head and neck reminded us continually of that of the Loon. 
Every now and then one would call co-co-co-co-co-co- 
keo ugh , keough , keough, the series of notes varying from ten 
or a dozen to twenty or twenty-five. T#is series, in both 
form and tone, resembled that of the Yellow-billed Cuckoo, 
but the notes are all louder and the keough s deeper and hol- 
lower. This call was almost invariably answered by another 
Grebe and frequently three or four would cry out in quick 
succession from various parts of the pond. Another sound
