within three feet of the ground), but when migrating it 

 may be found in the trees of lawns, orchards, and wood- 

 land and I have seen it among poke-berries. The Cape 

 May's song is a thin squeak which is compared to the 

 songs of the Black and White and also Black-poll Warblers.

Show me willows over water and any day in May or 

 June I'll show you a Yellow Warbler. Shade and fruit 

 trees also attract him and he may build his cotton-padded 

 nest in their branches or in the shrubbery below. The 

 song is a simple we-chee, chee, ckee, chee, cher-wee, resembling 

 that of the Chestnut-side, but has its own distinctive 

 tone which permits of ready identification, once it has been 

 learned. The bluish white eggs, thickly marked with 

 shades of brown, are laid the latter half of May.
