Lanner Falcon Part II

A few more photos of the ssp. erlangeri on 22.07.2012

Marsh Sandpiper

Today at Ponta da Erva ricefields in the Tagus Estuary the Marsh Sandpiper Tringa stagnatilis reported by another observer was still present, feeding along with Black-winged Stilts Himantopus himantopus.

In the past days another bird as been reported in the Estuary, this one seems to be a 1st summer bird. 

Lanner Falcon

A few photos, from the recently fledged juvenile Lanner, ssp erlangeri spotted at Baixo Alentejo last monday 03.07.2012 . The bird was perched on a small ridge of rocks, although the distance was great, so was the heat haze, and better digiscoped photos where impossible to obtain. The jizz was better for Lanner than Saker, with very long wings reaching the tail tip, very dark eye-line on a creamy head, and sandy/greyish tail wich contrast with the uniform brown mantle, scaps, coverts, and wings. The well patterned breast along with whitish tail tip pointed to a recently fledged juvenile. I watched the bird for about 20 minutes perched and flying, the latter gived an impression of a big Kestrel with long finelly barred tail, but very different from Peregrine with slower wing motion. The dark allmost black flight feathers, mainly the primaries, made an obvious contrast with the plain brown upperparts, wich is not seen on peregrines . The difficulty to differentiate juvenile North African Lanner from Juvenile Saker was still my main concern, since on that time the bird was perched, I couldnt see properly the fine streaked trousers.



On the day after 04.07.2012, 5 km on the NE direction from the previous sighthing location, I must run out of luck for the next months as the juvenile Lanner glided in front my eyes, and landed in front of me at no more than 30 meter distance. In the heat of the moment, I still manage to take some photos, where the streaked trousers are evident, the caractheristic head pattern of juvenile Lanner, with a dark triangle on the nape pointing down, the long and narrow moustache,  the dark "tiara" between the forehead and the crown, and the evident eye stripe. Then the bird went away on a very fast and powered flight, showing the plain (unpatterned) innermost (2) tailfeathers, with a slight dark band just before the obvious juvenile whitish tail tips.












It was of most help, Dick Forsman Raptors "Bible", wich sometimes I carry with me.... more than the photos, the text on big brown Falcons ID is crucial.

Atlas long-legged Buzzard

A few shots and  video recordings from Alentejo province

2 cy Atlas long-legged Buzzard Buteo rufinus cirtensis

Adult rufous morph Atlas long-legged Buzzard Buteo rufinus cirtensis

The peculiar feeding method of the ssp "cirtensis" chasing and capturing insects, on foot

I would like to thank to Andrea Corso and Luis Palma, for the confirmation of the Id, since rufous morph plumage on ssp. "cirtensis" do not figure on most bibliography.

White-rumped Swift

On all almost Madmax like film studio landscape, the old mines of  Minas de São Domingos in Baixo Alentejo have some very special visitors from mid May to late Summer, the White-rumped Swifts, Apus caffer.

The  contrasting colors of the acidic lagoon waters,  doesnt invite you to refresh your feet besides the 41ºC shown on the car console.
