Mr. Ilutcliins, in his notes on tlu' Hudson's liny l)ii(ls, states that the 

 Pigeon lliiwU " iniilves its nest on the roeks and in hollow trees, of sticks 

 and grass, lined with leathers, laying I'roni two to four white eggs, thinly 

 marked with red s])ots." As Hutehins has l)eeii fourid to he generally ([uite 

 accurate in his statements, and as this descriiition does not at all ajtply 

 either to the nest or the eggs of the rohiiiilnirius, it is ([uite possihle that he 

 may have mistaken this siiecies for the rig(!ou Hawk, and that this descrip- 

 tion of eggs and nests helongs not to ro/Kinbariiis, l)ut to richnnlsoiii.
