NOTES: (Species Sound: constant; Breeding Status: not territorial, breeding?, not breeding?; Behavioral Context: mate contact?; General Climate: arid; Cover Density: medium) Recordist's Note: "First part of this recording sounds like Mountain Bluebird, which was also nesting in this aspen grove. There was no mention of Mountain Bluebird on the original tape, and no break in the recording at the point where it launches into typical Cassin's Finch sound. Identification of the first part should be considered tentative." [The vocalizations in the first two parts of this recording (0:05-0:46, 0:47-1:00) are probably those of Carpodacus cassinii, despite their similarity to the song of a bluebird. If if indeed a vocalization of the finch, this probably represents a vocalization that is homologous to the "vireo" song described in the BNA account for C. purpureus, but not for C. cassinii (see also LNS #96373, #120291). The single true song and the calls at the end of the recording are certainly those of Carpodacus cassinii, the calls probably representing the "keeup/tidilip" calls described in BNA. There may also be some "tew" calls (e.g., 1:45, 2:49). Based on the calls given, I suspect that this is the same individual highlighted in LNS #80352 and #80353. The single song (1:02-1:06) ends with what appear to be imitations of Cyanocitta stelleri. Quality added (2, 1-2) - CAM - 4 February 2005]. Other Behaviors: Establish Flock Contact, Advertise. Habitat: Forest, Grassland, Freshwater, Evergreen Forest, Coniferous Forest, Meadow, Pasture, Second-growth, Scrub.
