Areas that were richer in species diversity saw fewer losses due to the virus, likely signaling the strength of a healthy ecosystem to battle a pathogen. Conservation needs to focus on certain species at times – as we at RTPI often do...

Murder of crows

This murder of crows filled the autumn sky earlier this afternoon in Pennsylvania. There may still be a lot of green on the horizon but it’s starting to feel a lot like fall, isn’t it? Flocks are forming and feeding is furious…
