Map n.1: Movements of Gata
Map n.2: Movements of Menta
GATA: Black vulture female. Born in 2007. Released in Boumort in 17.03.09. Ring 8R7.
MENTA: Black vulture female. Born in 2007. Released in Boumort in 17.03.09. Ring 8R4.
They looked like sisters, but they turned out to be so different that we could think of them as opposite ends of the home range spectrum. In between them, the rest of the colony is composed by a few members that travel a lot and many members that don’t travel too far.
Gata has just arrived at Boumort for the second time this year, after yet another long trip across the W and SW of Iberia, so she must know her way around by now and how to get to her favourite vulture restaurants across the vast landscapes.
Menta, on the other hand, has barely left the vicinity of Boumort since her release in 2009.
Gata is single and Menta has paired.
If we hadn’t fitted both females with the GPS transmitter that was funded by the RRE, we could only say that Gata is like the Guadiana river, nobody knowing where it comes and goes, and that Menta is like the local stream that flows from under the shade of Boumort, day in and day out, without barely a change.
GATA: 6.281 Km travelled this year (january-april). Daily average: 52,34 Km. Maximum distance travelled in one day: 329 Km. Maximum distance between to points: 1.016 Km Km.
MENTA: 232 Km travelled this year (january-april). Daily average: 2 Km. Maximum distance travelled in one day: 25 Km. Maximum distance between two points: 37 Km.
Quite a contrast!
