Black-necked Stilt
The Black-necked Stilt is most abundant in natural and man-made wetlands from the southern United States to southern South America. However, due to a northward expansion of the range, the species has increased in abundance in Canada relative to about 1970. The species was first observed to breed in Canada in 1977, and breeding has since been observed in several provinces. Sightings of non-breeders have also become more numerous. The cause of this range expansion is not entirely understood, but may be related to drought and changing land use to the south. However, with less than 1% of the global breeding population, Canada's responsibility for the species is very low.
They say there are about 1000 in Canada which is a pretty low count... It is the first time I ever saw one... A pretty looking bird....
