Large Home Range Estimate for Individuals with Low Number of Waypoints

[ofmerrit]

I have been estimating home ranges for Hermit Thrushes, and almost all of them have 15 or more waypoints associated with them. One individual, however, has 7 waypoints, and the home range estimate ctmmweb gives is 27 square hectares. This is a dramatic difference between the others, who have estimated home ranges between 4 and 10 square hectares.

My question is: is the model over-extrapolating since the individual only has 7 waypoints? The individual has one point that was not at first regarded as an outlier but may be. It's not, however, an outlier to that would make a 27 square hectare home range estimate.
