Hi James,
 
>Someone asked me about the term of nomad blue jays during this time of
year.  I am not familiar with this term or what it is called.  Can
anyone shed some light on this.

I can think of three uses for this term. The first applies to 'large
scale', long distance migration. Basically it refers to the fact that
the area that Blue Jays migrate to in winter is determined by weather
and food supply so can vary from year to year. Probably most migrant
species are nomadic to one extent or another on their wintering grounds.
On the small scale, while some Blue Jays are loyal to the same feeder
throughout the winter, many of the Blue Jays that you see at your feeder
are probably not the same individuals all winter. 'Nomadic' Blue Jays in
this case would refer to individuals who circulated around a large area,
visiting many feeding areas and never staying at the same one for very
long. The third use would be for single birds that are transiting
through an area in the summer. Probably non- or failed breeders. 
 
Interestingly it use to be thought that the nomadic flocks and
individuals were young birds but the most recent studies indicate that
both young and old birds will behave in this manner. Of course, Blue
Jays are found in Nova Scotia year round. To muddy the waters a bit, the
Blue Jays seen at feeders in Nova Scotia may or may not be locally
breeding birds. Also, studies indicate that the same Blue Jay may
migrate some years and not others. So while there may be loyal Blue Jays
such as the one that has been visiting Eleanor Lindsay's feeder for five
years (perhaps its injury has something to do with this?) few others may
be.
 
All the best,
 
Lance
