R script to simulate point-count data and estimate population trend under various scenarios of changing phenology
July 23, 2025
The script in this code repository simulates point-count data under an example scenario, sets up model input, and runs an N-mixture model with two components of detection (availability and perceptibility) to estimate the population trend. This simulation and analysis were developed to evaluate the consequences of changing spring phenology for estimating population trend of breeding bird populations via point-count surveys.

Accounting for seasonal patterns in bird availability prevents biased population trend estimates with advancing spring phenology Accounting for seasonal patterns in bird availability prevents biased population trend estimates with advancing spring phenology
Advancing spring phenology has been observed around the world, including changes in the timing of breeding of birds. When singing rates are tied to breeding stage, the rate at which birds are available for detection by surveyors can also show seasonal patterns that may shift with spring phenology. As the timing of peak bird availability changes over years, monitoring programs that do not...
