1x1 count, with media below. ML616421975. Characteristic flight calls, singled element ("syllable"), sharply downslurred, from 5kHz down to 2kHz, with the strong kink/crook in the middle around 3.5kHz, a powerful, pounding KYEWP! ML616421985. Several were singing! As here. After the bouts of song (mostly) end, you can still hear Type 2 flight calls of the main flock, plus a few "toop calls." Ambient noise (talking, cars in parking lot, NCAR generators) filtered out in this and all other recordings in this checklist; variable cutoff frequencies (100 Hz–1 kHz), dB rolloff always the lowest (6 dB rolloff). ML616421988, ML616421993, ML616422000, ML616422006. These are all from the same individual. ML616422009, ML616422013. Same individual. ML616422025. Adult female type feeding on ponderosa pine pinecones. The several loud beeps are Hannah Floyd texting me with updates on her Central Park (New York Co., NY) iNaturalist BioBlitz. ML616422026. This is one of those birds that, until recently, we would have called either a youngish adult male or a quote old adult female. However, that has all gone out the window with the Fernández-Eslava et al. (2021) paper in Evolution.
