Amazing video. Excellent quality. I love watching these birds take care of their young. I once watched a pair of Chestnut-backed Chickadees do this and it was amazing, sounds like you have so many birds there.
hi john. Do you (or any readers/viewers) have any idea where i could find a birdbath like the one in your 2012? bushtits mobbing video? It is the perfect perfect birdbath but i have never seen one with that tremendously gradual slope that makes the birds so safe. thank you. I suppose i will eventually try to make one but curing it so that the birds are safe makes me feel daunted.
Having no idea where you live I'd suggest Googling "cast cement birdbath" and see if there is a local outlet. I live in Portland, Oregon and there are always numerous places that make cast cement garden objects from birdbaths to benches to angels et al. though they do seem to come and go.
