They're Baaack! Yesterday morning (Sun, 14 Jun'26) while running our Breeding Bird Survey (BBS) east of Rangely (Rio Blanco Co., CO) we found at least two (2) CASSIN'S KINGBIRDs in the same spot where we first found them way back in 2021! What I find very interesting about this extralimital repeat is that we hadn't had them there the past two (2) years, only to find them in the same spot as they nested in 2023 (unfortunately they won't show up in the official BBS results as we found them outside the allotted time on our way back out). We figured they had given up their Mission after failing to attract more settlers, but the optimism of pioneers apparently carried on. If these are indeed the same individual birds, they would be at least six (6) years old as we found them as adults during our first year covering this route (Angora BBS) back in June 2021. While certainly plausible, it is also possible at least one is an offspring given the site fidelity - the armchair ornithologist in me wishes would have had them banded to know for sure. In any case, this is a fascinating occurrence for a rare species in northwestern Colorado. If you'd like specific details on the location, please let me know separately.
Good BBSing,
Doug
