Last year or maybe the year before there was a huge mortality event of woodcock in nyc during a snowstorm. Birds can exercise different strategies when migrating. Get there early and get best breeding territory while risking encountering death dealing weather.
The discussion the other day referred to local non-migratory birds already loosely on territory all winter and lengthening days elicit territorial singing. Also birds do call on speaking to each or her all throughout the year. This is different than singing. Thanks Sandy.
