The value of human resources changes with season for a social desert passerine bird

For desert species, human development may buffer against resource scarcity by providing reliable resources in an otherwise stark environment. We used high-throughput tracking technology to explore the movement patterns of a social desert passerine bird (the Arabian babbler-Argya quadriceps, Leiothrichidae) in a mosaic of human-modified and semi-natural habitats. From late summer to early winter, as natural food and water resources increase, we tracked 21 individuals representing 10 groups. Toward winter, groups spent less time within villages, had smaller home ranges, and were less territorial. In general, birds showed a preference for spending time in the vegetated semi-natural habitat. We further found that even a small section of uncultivated agricultural land (~2 km stretch of mostly bare dirt) can act as a movement barrier for babblers. Altogether, we highlight how the complex interaction between resource availability and anthropogenic changes to habitats, can shape animals' responses to our changing planet.
