Blackwater NWR contains a vibrant wildlife community and much of the wildlife is acclimated to a degree of human presence. This works wonders for the photographer since the critters do not flee at the first sight of humans. This is not to say that one can approach closely as visitors are restricted and the wildlife is wild, unlike the birds found in city parks.
The Canada geese tolerate humans at a distance; 80-100 yards seems to be their comfort range.
Small groups of geese took flight throughout the morning as they flew to the neighboring fields to feed.
Blackwater has both freshwater and brackish water habitat. Muskrat lodges dotted the brackish water swamps. Although we did not spot any muskrats during our visits their lodges indicate a substantial population.
