I was thinking about Angus's question as to why Limpkins and Anhingas haven't been present in the ongoing influx of southern species. I have no theory about Limpkins (since they *are* known to disperse widely at times)...but perhaps Anhingas' true lack of waterproofing (and, therefore, risk of hypothermia) severely limits how far north they can disperse, regardless of breeding success/habitat loss/etc on their home turf?
