Growth data for kittiwakes breeding in Middleton Island (Alaska)
<p>Data from the experimental manipulation of food availability during early development and at recruitment for a long-lived seabird, the black-legged kittiwake Rissa tridactyla, breeding on Middleton Island, Alaska. Birds were born and raised in nests with supplemented food (“Fed”) or unsupplemented control nests (“Unfed”), and later recruited into either Fed or Unfed nests.</p>

Activity time budget of red-legged kittiwakes during foraging trips as revealed by GPS loggers and accelerometers.
<p><sup>a</sup> Generalized linear mixed model (a binomial distribution) with likelihood ratio test was used. Trip identity and bird identity were included as fixed factor and random effect, respectively. See "Statistics" in the "<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0138850#sec002" target="_blank">Materials and Methods</a>".</p><p>Activity time budget of red-legged kittiwakes during foraging trips as revealed by GPS loggers and accelerometers.</p
Frequency distribution of ground speed (m/s) of red-legged kittiwakes as obtained by GPS loggers.
<p>The black arrow (3 m/s) shows a cut-off value discriminating flight and non-flight behaviors.</p
Behavioral patterns of red-legged kittiwakes as revealed by accelerometers.
<p>Panel A shows a time series of depth, heave acceleration, body angle, dominant amplitude of the heave acceleration, dominant cycle of the heave acceleration, and behavioral categories determined by accelerometry (the colors correspond to each behavioral category). Panel B shows enlarged records from panel A.</p
Locations of different types of behavior of red-legged kittiwakes as revealed by GPS loggers in relation to bathymetry.
<p>The blue dots represent flight behavior, the open light blue circles represent non-flight behavior (including foraging and resting on water) that occurred in ocean basin (where bottom depth >1,000 m), the open yellow circles represent non-flight behavior that occurred on the shelf break (bottom depth: 200 to 1000 m), and the open red circles represent non-flight behavior that occurred on the shelf (bottom depth: 0 to 200 m). The open green circles represent bathing behavior which occurred on land.</p
BLKI Data_forDRYAD
This file contains all the data used in the paper: physiological, morphological, and molecular data for Black-legged Kittiwake chicks in 2009 and 2011 from Middleton Island, Alaska. It includes chicks in supplementally fed nests and non-fed nests, chicks in experimentally enlarged nests (including fosters), and chicks in control nests of 2 natural chicks
Core feeding areas (50% contours of foraging locations) of black-legged kittiwakes from St. Paul and St. George Islands during trips to marine habitats.
<p>Trips to the shelf (A), and to the basin (B). Patterns: red = St. Paul; black = St. George; Years: 2008 = dots, 2009 = crossed lines, 2010 = diagonal lines.</p
Acoustically measured biomass density (g/m<sup>2</sup>) of juvenile pollock integrated from 100 m to the surface.
<p>Data were collected from mid-July to mid-August in each year over 110 transects of 10 km in length that were randomly placed within 200 km of St. George Island. Map surfaces were generated using minimum curvature interpolation.</p
Linear mixed model of trip distance of black-legged kittiwakes with colony (St. Paul = STP; St. George = STG) and habitat (Shelf and Basin) as fixed factors and individual as a random factor.
<p>Statistically significant (<i>P</i> < 0.025 after Bonferroni correction) relationships are shown in bold (see text for post-hoc comparisons).</p
