The first island has been sampled. Likely we had good weather and animals were collaborating. Looking forward to calculate an estimate of population size from the CMR data collected.Only five to go!

A GEDAi member within the Short Listed most influencial authors!
Congratulations to Ana Sanz-Aguilar from the GEDAi, short-listed among the ten most influencial authors in the 'Natural Resouces' area in the Balearic region during the period 2017-2019.
Well done for a well deserved recognition! The whole GEDAi is very proud of your success !

New Publication on European Storm Petrel : foraging areas revealed for the first time !
Rotger, A., Sola, A., Tavecchia, G. and Sanz-Aguilar, A. 2020. Foraging Far from Home: Gps-Tracking of Mediterranean Storm-Petrels Hydrobates pelagicus melitensis Reveals Long-Distance Foraging Movements. Ardeola, 68(1):3-16 (2020). https://doi.org/10.13157/arla.68.1.2021.ra1
Abstract: Identifying important foraging areas is fundamental to detecting the
demographic drivers of a species and ultimately to plan conservation
measures. For some species, such as small pelagic seabirds, foraging
grounds are difficult to locate and remain largely unknown. We used
miniaturised GPS devices (∼0.95g) to study foraging movements of
Mediterranean Storm-petrels Hydrobates pelagicus melitensis during the
incubation period. A total of 43 individuals at Benidorm colony
(southwestern Mediterranean Sea) were tracked during a single foraging
trip. We first assessed potential negative effects of the tracking
devices.
We recorded 22 complete foraging trips and measured home-range,
foraging areas and the degree of overlap among individuals. We used
first passage time analyses (FPT) to differentiate foraging/resting from
flying/travelling activities and to infer potential foraging areas. All
tracked birds returned to the colony. On average, individual body
weight slightly decreased after foraging trips, suggesting a small
immediate negative effect of the device. Tracked birds had high breeding
success (0.71). Foraging trips lasted between 1 and 4.5 days with the
total distance travelled ranging between 303.14 and 1,726.53km. The
visited areas covered the whole south-western part of the Mediterranean
Sea. Tracked individuals shared more than 50% of their home-range areas.
Foraging areas were located further from the colony than previously
thought (from 240 to 469km away) on deep sea areas of the Alboran Sea
and Cartagena Canyons. Further studies are needed to locate foraging
grounds during other life-cycle periods and to evaluate repeatability
yearly, in order to determine the important marine areas for the
species.—Rotger, A., Sola, A., Tavecchia, G. & Sanz-Aguilar, A.

Storm Petrel 3rd campaign!
The third Storm Petrel campaign in 2020 is ongoing. This will be the 27th year of monitoring at Benidorm Island. Congratulation to all who made this possible, especially to A Sanz-Aguilar who kept the study alive during the last 13 years. More we study them, more these little birds surprise us.

First Griffon vulture marked in the wild in Mallorca!
The GEDAi helped the marking of the first Griffon vulture in the wild. It was a young bird taken from its nest just before fledgling (weighting ~7kg!). The Griffon Vulture arrived in Mallorca island in 2008 as a consequence of a huge storm. Since 2012 it breeds in the island.The bird has been equipped with a GMS/GPS radio, sponsored by the Vulture Conservation Fundation, under the supervision of Dra A. Cortés-Avizanda. Keep posted to see how and where it flies.
