Colour-ringed Short-toed Eagle

Jul 5, 2008 / 7 Comments
Short-toed Eagle (CIRCAETUS GALLICUS) / by KING R. 2008

Date: 30th April 2008
Time: 18:50
Species: Short-toed Eagle
Location: Jews Gate Bird Observatory, Gibraltar
Rings: Two colour rings on left leg, Green over Red

Details: The bird was migrating north, seen arriving over the Straits of Gibraltar from Africa, then being mobbed by the resident pair of Ravens and many Yellow-legged Gulls. The bird passed low overhead before continuing northwards into Spain.

I’m interested to know when and where the bird was ringed and any further information you can supply.

Biotopes. Retuerta de Pina (Spain)

Jul 5, 2008 / Comment
Contributor: Javier Blasco-Zumeta.
Country: Spain. Province: Zaragoza. Place: Retuerta de Pina.

Please take a look at the map of the area. General botanical description and a photo can be viewed below:

Short-toed Eagle. Biotopes. Photo 1La Retuerta is situated in the central part of the Ebro valley, east of Zaragoza, in northeastern Spain. The extreme climatic conditions of the area have produced a vegetation similar to that of the North-African steppes. This climate can be summarized as follows: large annual range of minimum and maximum temperatures, oscillating from -10 oC to more than +40 oC; frequent frost in spring; prevailing winds from the NW and the SE (cold and warm, respectively), both with great desiccating power; low annual rainfall (200-400 mm); water deficit over 300 mm.
