Clarification about the Movebank Acceleration Viewer

Hi all,

Broken pinger/download antenna - effect on performance

Note from Meg Crofoot who is tracking a capuchin monkey with a broken antenna

GPS Performance

Notes on fix success and time-outs. Sharing this information will help folks pick the best time-out time for a species, and estimate battery life.
Here are some results from the first two kinkajous.  These are arboreal species that sleep in holes all day, and then come out at night.  They may also go into sleeping spots at night.

Male: 312 fix attempts, 280 success, 90%. Ave time to fix 38sec, excluding time-outs = 31sec. 

Female: 155 fix attempts, 119 success, 76%, Ave TTF 50, excluding to’s 36.

Discussion on eobs Pingers

I thought I would start this off with some of my observation on Pinger range. For the mammal tracking I've been involved with it seems the pinger range is a critical issue as finding the animals to get a download has been the most difficult aspects of tracking.

Aerial Telemetry

I'd like to hear suggestions and experiences from others who have attempted aerial telemetry on radio collared animals.

After having difficulty locating my study animals (Martes pennanti) from the ground, I was fortunate to get regular access to some air time from local law enforcement.  We have access to a small, fixed wing plane, where we have one directional antenna mounted to each wing.  Our flights are purely for our purposes, i.e., our air time is devoted solely to locating our animals.
