Genotype predicts quantitative song variety in a chickadee hybrid zone despite limited sampling

In the avian sub-order Passeri (the songbirds), song develops according to both a flexible neural template and auditory input from conspecifics, making innately-constrained characters of song difficult to isolate. In a hybridizing population of Black-capped Chickadees (Poecile atricapillus) and Carolina Chickadees (Poecile carolinensis), we found that genetic ancestry was weakly predictive of a multidimensional measure of song variety (a continuously distributed quantitative alternative to categorical song repertoire size) but did not successfully predict one-dimensional song variety. We used species-diagnostic autosomal markers to genotype 55 individuals inside and outside of the Black-capped Chickadee/Carolina Chickadee hybrid zone in Missouri and Kansas. Using active recording methods, we then obtained high-volume, high-quality song recordings of 10 genotyped chickadees from a single hybrid zone population on a small, lake-bounded peninsula in west-central Missouri. We extracted acou..., , , # Data from: Genotype predicts quantitative song variety in a chickadee hybrid zone despite limited sampling

### Files and variables

## Folders

#### Sparrowfoot_Park_original_recordings.zip

**Description:** This folder contains the recordings made at Sparrowfoot Park from which data were extracted in their original state. Recordings are split into folders by individual bird, and each folder is named with the bird's individual ID code used in publication and, in parentheses, an informal name with which it was referred to in the field. Metadata is included verbally at the end of each recording and embedded within the file names in the following format: `Poecile.sp_LeftColorBands.RightColorBands_Date_Locality.County.State_RecordistInitials_RecordingSequence`. All files are in `.wav` format.
