No other fro;^- on I.ontj Island has a call that resembles the call of the 
sprin.ii peeper. V.'histlin.y;, i)eeping sounds heard in a I.ontf Island marsh 
in April are almost surel\ the sounds of sjiring jieepers. In western New 
York, s]iring ]>eepers are less abundant than on Long Island, and their 
places are largeh- taken b>- swamp cricket frogs, whose j^eeps somewhat 
resemble those of the Long Island spring ]ieepers. The voices of the 
swam]) cricket frogs ma\' l)e recognized b>- their trillings, which are \-ery 
distinct and coarse. 
The voices of s]iring peepers ma\' be expected about March fifteenth. 
In 1913. the chorus was loud on the .sixteenth, although occasional sounds 
■ had been heard for three or four days previously. Tire chorus of their 
songs continues until about the middle of June. 
Spring i)eepers are not \-oung frogs of other s]iecies Init are full- 
grown tree frogs. Thev have discs on the ends of their toes and are ex- 
pert climbers. They leave the jwnds at the end of the breeding season, 
and ma>' afterward be found on orchard trees, or in damp grass through- 
out the warm months. The\- la>- their eggs .singly, attached to sub- 
merged sticks or blades of grass. These frogs are the least .shy of all our 
frogs and toads. The\' ma>- readih- be a])])roached with a bright lantern.
