| Three occupied holes this spring (1 last year) - two near Rainbow Bridge and one in Lady Margaret Hall grounds. One hole seems to have produced one fledged young (as a bird without tail streamers is now associating with the adults) one was apparently only attended by a single bird in recent weeks so probably did not produce fledged young, and one (in LMH) still seems actively attended by a pair. |
