Great Blue Heron off nests

[bw4sz]

i'm seeing too many examples of great blue heron empty nests being predicted as great blue heron.

This is either because all the images we have of great blue herons are on nests, or there are some training data with empty nests that are labeled great blue heron. We need to review the training data to be sure. If not ask Lindsey to find roosting great blue herons off nest.
