title: Sound recordings of courtship displays of Allen's (Selasphorus sasin), Rufous (S. rufus), and Hybrid (S. sasin x S. rufus) hummingbirds recorded between 2014 and 2021 in California, Oregon, and Alaska

description: These are sound recordings of courtship displays that are associated with
 the 386 individual Selasphorus hummingbirds that are the focus of analyses
 presented in Myers et al 2022. A subset of these birds were also used in
 Myers et al. (2019), and 159 of them have been deposited as
 specimens in the San Diego State University Museum of Biodiversity or the
 San Diego Natural History Museum.  Many recordings will include a
 verbal tag from CJC, BMM or DTR stating relevant recording conditions
 (e.g. date, locality). Each subfolder contains the recordings for 1 bird.
 Unfortunately, recordings for 15 birds were lost in a hard-drive
 crash.  Moreover, we recorded many additional birds which we were
 thereafter unable to catch. Some of those not-analyzed birds are also
 included here, even though they were not included in the associated
 studies, since we lacked a DNA sample, morphometrics, or feathers.
description: Sound recordings of
 courtship displays of wild hummingbirds including Allen's
 (<em>Selasphorus sasin</em>), Rufous (<em>Selasphrous
 rufus</em>) and their hybirds (<em>Selasphorus sasin
 </em>x <em>Selasphorus rufus</em>). Sound recordings
 have been placed in folders by recording year, then according to a
 field identifier (such as a field ID, or a locality). All files are the
 original .wav.  Generally the recordings are un-cropped, except in
 rare instances in which the recorder was accidentally left running for a
 long time. The
 full dataset has been split into 13 different zipped folders:
 "2014", "2015", "hybrid localities
 2016-2018" (6 parts), "Allen's localities 2016-2018",
 "Rufous localities 2016-2018", "2019 Brian" "2019
 David and Chris" and "2021".  Please refer to Myers et al 2022
 for field recording methods. 
description: The recordings are 16 or 24 bit .wav files, recorded at 44.1, 48,
 or 96 kHz. CJC generally recorded with a Sound Devices 702 recorder and a
 Telinga pro parabola with a Sennheiser MKH 20 microphone. BMM recorded
 with combinations of a Sennheiser MKH 70 shotgun microphone, an
 Audio-Technica AT875R shotgun microphone, a Tascam DR-05 portable
 recorder, a Tascam DR-60DmkII audio recorder. DTR recorded with any of the
 above. CJC recordings from Ketchikan, Alaska in 2018 also include voice of
 Alan Brelsford, while BMM recordings from 2018 include Zachary Williams
 and in 2019 include voice of Kevin Burns. Some
 sub-folders contain recordings as initially named by the recorder (name is
 unedited); others the file name has been edited (but retains original name
 given by the recorder). For birds only identified by a field ID, an
 associated table "bird locality & lookup table.xls"
 should provide enough information to associate each individual folder with
 the "Main ID" provided in the paper.  Also note that,
 occasionally, some display bouts will span multiple recordings, if (for
 example) the 'rec' button on a recorder got pressed multiple
 times during a display bout.  Note that, as the
 recordings were verbally annotated in real time, it was somewhat common
 for the recordist mis-speak in the recorded annotations. This was
 particularly true for repetitions pendulum display counts, because it was
 easy to mis-count the number of pendulum displays in real-time.  Therefore
 the digitized sequences reflect our analysis of the sounds themselves
 rather than the verbatim verbal tag. Also note: the definitions of
 behaviors are as given in Myers et al 2022. See the supplemental
 materials, which includes figure S1 that shows example sequences with
 multiple possible mappings from sounds onto defined behaviors. 
 Allen's type dives begin with what sounds like a pendulum display
 (the 'incorporated pendulum') but was coded as part of the dive,
 and not a pendulum.
