Hi there,
I’ve been a PhD student at Theunis Piersma’s lab in the Netherlands and as you probably know there’s a wealth of papers and ideas about it. The difficulty I see at the moment is the question you want to address… How they utilize the mudflat is dependent on so many factors, but most importantly is the food (availability and quality). If birds stay put at given location, do they stay there because there is ample food, or are they just digesting or evading predation danger (i.e. not foraging)? This is dependent on the time of year as well. I’d be curious to see how well their movements are detected by Motus, as many small scale movements are likely undetected, but very important for the birds.
Have a look at these papers:
Bijleveld, A. I., S. Twietmeyer, J. Piechocki, J. A. van Gils, and T. Piersma. 2015. Natural selection by pulsed predation: survival of the thickest. Ecology 96:1943-1956.
van Gils, J. A., A. Dekinga, B. Spaans, W. K. Vahl, and T. Piersma. 2005. Digestive bottleneck affects foraging decisions in red knots Calidris canutus. II. Patch choice and length of working day. Journal of Animal Ecology 74:120-130.
van Gils, J. A., B. Spaans, A. Dekinga, and T. Piersma. 2006. Foraging in a tidally structured environment by red knots (Calidris canutus): ideal, but not free. Ecology 87:1189-1202.
Anyways, I’d be happy to discuss this a bit further of the motus-wts mailing list and feel free to contact me.
Best wishes,
Sjoerd
