Tracking small songbirds generates important insights into avian ecology, but does not always work out the way you planned. We published a paper about these experiences in the Journal of Avian Biology:
Context‐dependent effects of radio transmitter attachment on a small passerine. Snijders, L., Weme, L. E., Goede, P., Savage, J. L., Oers, K., & Naguib, M. 2016. Journal of Avian Biology. DOI: 10.1111/jav.01148.
And this month I had the honour to write a blog for the British Ornithologists’ Union (BOU) to explain our findings: see the BOU blog.
