SEAZ Birds: The Missing Tracks, Disc 1
Disc 1: Quail to Hummingbirds
by Diana Doyle
This album of the “missing tracks” for Southeast Arizona’s Sky Islands is intended to supplement the popular national-coverage app, Sibley eGuide to Birds. The album currently has five “discs” with 117 audio tracks of 75 species, including regular species with missing calls, annual specialties, local subspecies, rarities, and the rare but potential dream-birds:
Regular Species— Locally common birds that are missing vocalizations often heard in Southeast Arizona, such as Buff-breasted Flycatcher’s “pit” and Crissal Thrasher’s “pjurrre-djurre” call.
Annual Specialties— South-of-the-border species that are typically seen annually, such as Black-capped Gnatcatcher and Lucifer Hummingbird.
Subspecies— Mexican subspecies of familiar birds, with regional songs that make them confusing to visiting birders, such as Bewick’s Wren and Brown Creeper.
Rarities— Species that don’t appear annually in Southeast Arizona, such as Eared Quetzal, Sinaloa Wren, and Tufted Flycatcher.
Potential Rarities— Twelve species not yet on the AZFO Bird Checklist, but expected given their patterns of vagrancy or their distribution in the adjacent Mexican state of Sonora. Marked with an asterisk in the audio file name, examples are Orange-billed Nightingale-Thrush and Rusty Sparrow.

I’m glad to be able to share these with such a great organization as ABA! For those who aren’t familiar with creating an album with various artists and cover art in iTunes, here’s a quick primer: For each album: 1) Drag the set of 20-ish audio files into iTunes. 2) Highlight to select all those audio tracks in iTunes. 3) Choose Get Info, and click yes when asked if want to edit multiple items, then select the checkbox “Album is a compilation of songs by various artists”. 4) While still in the Get Info window, click on the Artwork tab… Read more »
Diana, this is fantastic! Quick question: Is the Sibley app supplement a separate thing? If so, how is it obtained?
Hi Jason, This isn’t a Sibley app supplement, and has no affiliation with the Sibley app. But this set of audio tracks are the vocalizations for SE AZ that are missing in the Sibley app, in this sense it “supplements” or “adds”. For example, in the Sibley app there are no vocalizations for Rufous-capped Warbler. With “The MIssing Tracks” in your iTunes library, then you’d have those vocalizations handy, either for study or in the field.
Thanks, Diana. These are incredibly useful!
