Growth, movement, and survival of precocial shorebird chicks are constrained by local conditions

Young animals are often less mobile than adults, while also having high energetic demands. They may therefore be more vulnerable to local-scale changes in environmental conditions. In particular, when one sex must grow more rapidly than the other to achieve a larger adult size, that sex may experience especially dramatic reductions in growth and survival in the face of suboptimal environmental conditions. In order to investigate the flexibility of individuals in response to local-scale environmental variation during development, we studied the sex-specific growth, movement, and survival of Hudsonian Godwit (Limosa haemastica) chicks – a sexually dimorphic, precocial shorebird that breeds in the sub-Arctic and exhibits a male-skewed adult sex ratio. We found that female chicks – which must grow to a larger adult size – reached their maximum growth rates at a later age, but had similar growth rates to males before that and survived equally well to 21 days. We also found that, irrespective..., , # Data from: Growth, movement, and survival of precocial shorebird chicks are constrained by local conditions

## Description of the data and file structure

We studied the sex-specific growth, movement, and survival of Hudsonian Godwit (*Limosa haemastica*) chicks to investigate the flexibility of individuals in response to local-scale environmental variation during development. Data were collected during the summers of 2009–2011 and 2019–2024 in Beluga, Alaska.

幼崽通常较成体活动能力更弱，同时却有着极高的能量需求。因此它们可能更易受到局域环境条件变化的影响。具体而言，当某一性别为达到更大的成体体型而需要比另一性别更快生长时，该性别在环境条件不佳的情况下，其生长与存活可能会出现尤为显著的下降。为探究个体在发育过程中对局域环境变化的响应灵活性，我们研究了哈德逊滨鹬（Hudsonian Godwit, *Limosa haemastica*）幼雏的性别特异性生长、活动与存活情况。该物种为性二态的早成涉禽，繁殖于亚北极区域，成体性比呈现雄性偏倚特征。我们发现，需生长至更大成体体型的雌性幼雏，其最高生长速率出现的时间晚于雄性，但在此之前二者的生长速率并无显著差异，且至21日龄时二者的存活率持平。此外我们还发现，无论[原文内容截断]……
