BULLETIN 1165, U. S. DEPARTMENT OF AGRICULTURE. 



are cultivated, in gardens and a small cornfield. The tract contains 

 three small rain-water ponds without outlets, 6 acres of tidal marsh, 

 and 6 to 8 acres of coarse grass inclined to swamp. About a third of 

 the entire area is covered with timber, mostly pine, with a few 

 cypresses and live oaks near the river. The remainder is open grass- 

 land having some scrub palmetto, and most of it used for grazing. 

 At St. Marks the average number of species was 36, with a total of 

 44, of which 29 were present every year, and there were only 4 species 

 that were found only one year each. (See Table 9.) 



A considerable contrast is noticeable between this area and that 

 near Whiting, Ind., in regard to the stability of the species nesting, 

 as will be seen in the accompanying Tables 8 and 9. At Whiting, 

 Ind., the species present every year were 18 per cent of the entire 

 number found and 38 per cent were present only a single year. 

 At St. Marks, Fla., on the other hand, 64 per cent of the species 

 were present every year, while those found only once represented 

 only 9 per cent.
