creeks that thread their way alternately between small heavily wooded 

 hammocks and beautiful islands all covered with undergrowth almost 

 tropical in aspect, and bordered by luxuriant growths of tall marsh grass 

 swaying in the gentle summer breeze. In such an environment the wiry 

 trill of the Marsh Wren is the first bird voice to be heard at the morning 

 awakening. This species breeds numerously in the county, being confined 

 exclusively to salt water marshes. On May 9, among the marshes border- 

 ing the islands and hammocks north of St. Catherine's island, I examined 

 many nests containing from one to five eggs. The latter number consti- 

 tutes the full complement. The nests were globular in shape, with the 

 entrance on the side, and were composed of the blades and stems of the 

 marsh grass. They were placed in the tall grass well out of reach of high 

 tides. This bird constructs many nests which apparently are never occu- 

 pied, although I am not aware that anyone has carried on observations in 

 one of their colonies sufficiently continuous to prove conclusively that these 

 nests are not used in some way. 



A THREE MONTHS' LIST OF THE BIRDS OF PINELLAS 

 COUNTY, FLORIDA. 



BY MAJOR CLIFFORD H. PANGBURN, A.R.C. 



The observations upon which the following list is based were 

 made during a period extending from January 22 to April 29, 1918. 

 The region covered included the greater part of Pinellas County, 

 Florida, although most of the time was spent in the southern part 

 of the county around the city of St. Petersburg, and along the keys 

 which separate the Gulf of Mexico from the mainland. 



Pinellas County is in the form of a peninsula about seven or eight 

 miles wide at the widest point, and tapering to a blunt end at the 

 southern end. Along the east side is Tampa Bay, on which is 

 located St. Petersburg, a city of about 15,000, which has nearly 

 double that population in the winter. Tampa is about fifty miles 

 distant, up and across the bay. 



On the west side of the county lies Boca Ceiga Bay, from which 

 there are a few passes opening into the Gulf of Mexico between the 

 keys. These are for the most part very narrow. The keys them-
