How big are the Canada's shooterwalker? Residents are normally giants.
They call them greaters I believe. If they ever get really established people are going to start complaining about the mess they leave. I use to spend a lot of time in Indiana and the people that had lakefront up there were always looking for ways to keeep them off their yards. Goose carp is nasty stuff. ever heard the saying "carp like a goose"
All Canada Geese are actually Greater Canada Geese. Though I too tend to just call small Canadas Lessers and large Canadas Greaters because I can't tell one from another. And I am sure the common names vary and are regional. Cacklers are now a separate species. I tried to identify some resident geese I killed in the last three years and eventually just gave up. There are four subspecies of Branta canadensis in Texas
maxima (Giant) This is the largest and the one that was mostly stocked by Oklahoma on purpose. Why I think some of the ones I have taken East and North of DFW may be this one.
interior (?) Another Large one probably more east texas and upper coast. I am sure I have taken some of these as residents too and just called them greaters or giants for not knowing what to call any of them really.
moffiti (Moffitt's) Another Large one, may be the ones found more west in Texas, but also the central coast.
parvipes (Lesser) The smaller ones, but bigger than cacklers. I think I have killed these as migrants just about everywhere I have ever hunted Canada geese.
Some north Texas Residents that have never been to Canada and never will.
