# Demographic, behavioral, and ecological data from a long-term field study of wild baboons in Amboseli, Kenya

## TL;DR

This paper introduces publicly available long-term data on wild baboons in Kenya, covering demographics, behavior, diet, and weather from 1971 to 2023.

## Contribution

The paper makes four new data sets from a 50+ year baboon study publicly accessible for ecological and behavioral research.

## Key findings

- The data sets span demographics, activity budgets, diet, and weather for wild baboons in Amboseli.
- The data are aggregated annually and monthly to facilitate cross-data set analyses.
- These data provide a rare longitudinal view of behavioral and ecological changes in a wild mammal population.

## Abstract

Long-term data sets on individually recognized animals and their environments are critical to understanding animal behavior, evolution, and ecology. However, they are resource- and time-intensive and seldom made publicly available. The Amboseli Baboon Research Project (ABRP) is one of the longest-running studies of a wild mammal population in the world and has collected extensive data on the baboon population of the Amboseli ecosystem in Kenya since 1971. Here, we describe four ABRP data sets newly available to the evolutionary biology, behavioral ecology, and primatology communities: (1) the sizes and demographic compositions of 21 social groups from 1971–2023; (2) the activity budgets of adult females and immatures from 1984–2023; (3) behavioral data on diet for adult females and immatures from 1984–2023; and (4) weather data, including precipitation from 1976–2023 and temperature from 1976–2022. Data are aggregated annually and monthly to enable cross-data set analyses. These data offer a rare longitudinal perspective on behavioral and ecological change in a wild mammal population.
