A friend fromOntario, Rev. Giles G. Brown, whosaw the eggs, assured me that all whichhe had ever seen near his native homewere of the same description. April is the usual month for nesting,but birds are sometimes seen gatheringnest materials during the first week inA-Iarch, and incubation is often underway before the end of the month. Onlyone brood is provided for in a seasonunless some accident liefalls the first, inwhich case another nest is more hastilyprepared at some distance from thescene of former disaster. Deposition of.

It has been supposed that the Crow retires from our state except in verymild winters. My impression is that this is not usually the case, but thatthe birds congregate in vast winter companies or roosts of local restriction,and chiefly within our borders. Ten such roosts have been reported by Pro-fessor Butler from the neighboring state of Indiana, and it is improbablethat the habit of our birds materially differs. I have information of fivesuch roosts (including one across the Ohio River in West Virginia, oppositeGallia County, and which is largely patronized by Ohio birds), noted at dif-feren
