Quantitative genetics of plumage color

This is an excel file with 5 worksheets containing datasets used for different analyses shown in the paper. 1) Comparing color between sexes and developmental stages, 2) Frequency of extra-pair young (EPY) across years, 3) Comparing color of recruited vs. non-recruited individuals, 4) Within-individual color comparison of recruited individuals, and 5) data used in the animal model analysis. See the ReadMe file for more details

CORT3_070114

Text file containing all pertinent data for the bivariate animal model we ran to assess heritability of variation in baseline and stress-induced corticosterone (CORT) concentrations in nestling barn swallows. This file is similar to the excel file available in this datafile but in a format more easily accessible to R statistical program

NestlingBarnSwallowCORT2010-HeritabilityMS

Contains data for USGS-banded nestling North American barn swallows (Hirundo rustica erythrogaster) collected at day 12 between May and July 2010. Data includes site and nest location, date banded, brood size manipulation treatment, age at data collection, sex, brood number (based on breeding adult pair), clutch size, brood size, mass, presence of mites, DNA extraction number, social and genetic assignments of parents, date and time information for baseline and stress-induced corticosterone (CORT) samples, CORT concentrations, and plumage color score

Performance of Encounternet Tags: Field Tests of Miniaturized Proximity Loggers for Use on Small Birds

<div><p>Proximity logging is a new tool for understanding social behavior as it allows for accurate quantification of social networks. We report results from field calibration and deployment tests of miniaturized proximity tags (Encounternet), digital transceivers that log encounters between tagged individuals. We examined radio signal behavior in relation to tag attachment (tag, tag on bird, tag on saline-filled balloon) to understand how radio signal strength is affected by the tag mounting technique used for calibration tests. We investigated inter-tag and inter-receiver station variability, and in each calibration test we accounted for the effects of antennae orientation. Additionally, we used data from a live deployment on breeding barn swallows (<i>Hirundo rustica erythrogaster</i>) to analyze the quality of the logs, including reciprocal agreement in dyadic logs. We evaluated the impact (in terms of mass changes) of tag attachment on the birds. We were able to statistically distinguish between RSSI values associated with different close-proximity (<5m) tag-tag distances regardless of antennae orientation. Inter-tag variability was low, but we did find significant inter-receiver station variability. Reciprocal agreement of dyadic logs was high and social networks were constructed from proximity tag logs based on two different RSSI thresholds. There was no evidence of significant mass loss in the time birds were wearing tags. We conclude that proximity loggers are accurate and effective for quantifying social behavior. However, because RSSI and distance cannot be perfectly resolved, data from proximity loggers are most appropriate for comparing networks based on specific RSSI thresholds. The Encounternet system is flexible and customizable, and tags are now light enough for use on small animals (<50g).</p></div

(A) Network constructed from 975 contacts between tagged barn swallows where logs had maximum RSSI values ≥ 0 = proximity < 5m (edges scaled to 1/5). (B) Network constructed from 88 contacts between tagged barn swallows where logs had maximum RSSI values ≥ 40 = proximity < 0.1m.

<p>In both cases, n = 17 tagged barn swallows with females in white and males in gray. Data are from 15 hours of logging over three days. Node labels correspond to the bird’s tag ID.</p
