GPS data

Discover a few examples of our GPS data. On all the pictures below, blue stands for the GPS track of the male and red is the GPS track of the female. Each yellow pin is the location of a nest box.

Thanks to GPS data, we can for example determine favorite hunting area. In the green circle on the map below, we can see that the male prefer to hunt in a particular field.

Males are sometimes polygamous, which means they take care of two brood in the same time (with two different females). It was probably the case for this male below: we see that he has spend a lot of time around two, in only ten days.

Barn owls are sometimes in cities ! Here, the family bred in Ecublens and went hunting in a small forest north of their nest.

It is mainly males that go hunting in barn owls. Thus, they stay in a relatively small permimeter around their nest (around 2 km). The female goes sometimes visiting other nest boxes, as we see on the map below. During some nights, she passes from one nest box to another. We think that she looks for a place for a future breeding event.
