PASSERES TYRANNIDAE M.CRINITUS VAR. CINERASCENS. 345 



not often seen among the trees, but later it selects an open piece of woods, 

 and builds its nest in one of the taller pines. This does not differ materially 

 from those of either T. carolinensis or T. verticalis, but it is a little more 

 neatly and compactly made, and the eggs, I think, are usually larger than 

 those of the other species. All three of these flycatchers may sometimes be 

 found nesting within a short distance of each other, and it is interesting to 

 note the different locations which each selects for its domicile: carolinensis 

 usually builds in a crotch, or where a branch springs from the main trunk 

 of the tree ; verticalis almost invariably builds midway on a horizontal limb ; 

 while vociferans selects a fork at the extremity of the branch. I have never 

 found but three eggs in the nest of the latter, while the full clutch of the 

 others is four."
