Observation details
Including one recorded that was alternating between typical up slurred call note and a perfect imitation of a blue Jay call note. Probably learned/imprinted I’m guessing rather than actual mimicry, but quite a shock, regardless. 1998 Greenlaw et al. have a paper describing this & EATO giving vocalizations of Brown Thrasher & Am. Robin.
