Résumé :
|
The importance of birds in the diet of the Pharaoh Eagle-Owl Bubo ascalaphus at Oued Massa (Morocco) and Banc d’Arguin National Park (Mauritania). The diet of the Pharaoh Eagle-Owl Bubo ascalaphus was studied at Oued Massa, Morocco (220 prey items determined in 1995) and at Cape Tafarit, Banc d’Arguin National Park, Mauritania (2656 prey items identified between 1997 and 1999). Many birds are captured in these two sites. They represent 43.2% of the prey at Oued Massa (especially Barn Swallows Hirundo rustica 11.8% and sparrows Passer sp. 10.5% of the diet), and even 71.0% at Cap Tafarit with waders as the main prey (56.6%, especially Dunlin Calidris alpina 24.7%, Red Knot Calidris canutus 8.1% and Common Ringed Plover Charadrius hiaticula 6.4%). No other study on the diet of this owl shows such proportions of birds captured, highlighting the ability of the Pharaoh Eagle-Owl to exploit river or sea edges where large numbers of birds are concentrated.
