Hi,

I have a set of GPS fixes from GPS tagged owls. The GPS was programmed to send 3 GPS positions (fixes) during the night (2 hours before midnight, midnight and 2 hours after midnight). The GPS senders were active between 1- 3 years. I will calculate Kernel and minimum convex polygon (MCP) home ranges, and finally I will analyse habitat selection.

Within each home range I will create random points reflecting habitat availability. The habitat will be compared between owl fixes and random points to estimate habitat selection.

So far it is straightforward. Although the owl lives along the coast and alternates between being on mainland and group of islands. Hence, within the home range area there are large water bodies, which the owl are only crossing.

I think the best procedure for the habitat analysis is exclude the large water bodies. Although, I would be happy to get some recommendations.

Best regards,

Ronny
