There has been a bird nest on my rain gutter for the past four summers. Each summer a new type of bird has inhabited it and built upon it. Each layer is distinct and looks unique (I assume due to the different construction techniques of the different species).
The nest is now quite tall and approaching the roof, so there’s not room for another layer of nest. After the current inhabitants leave, would this nest be of interest to, say, a wildlife center or other place for elementary education? Or are these quite common and uninteresting?
