Impact of human disturbance on the abundance of non‐breeding shorebirds in a subtropical wetland
Biotropica, Volume 54, Issue 5, Page 1160-1169, September 2022., 2022 We studied the influence of human disturbance in shorebirds, a subtropical coastal wetland in Mexico. During the winter, all shorebird species were negatively related to human disturbance but positively associated with the presence of raptors. Understanding the factors influencing the abundance and habitat use of shorebirds on their non‐breeding ...
