These birds are clearly different enough from the Shorelarks we see on the british coast to be worthy of a sub-species. In addition to their deeper tan colouration on the head and nape, shown best in the first photo, they live in snow at 2600m and above! I spent a fair bit of time with them at Oukaimeden ski centre in Morocco, and was pleased to get some nice images, though getting a decent background was always a challenge, and they preferred a busy car park. As you can see, they like bread, and can be encouraged to move to nicer spots by leaving a little trail..... The background of the two photos at the end of the sequence is actually a car, and the rock was placed on a wall with various bits of bread scattered around. Almost all the images preceding the ones with the blue-ish background were all leading up to it, I just couldn't resist pressing the shutter! If I learnt one thing in Morocco it's that planning goes a huge way to making images that much better. Plan the perch, plan the background, get the light behind you, set up, pre-focus, and WAIT! Click, and happy days! All these with the 1D Mark IV, the 800mm lens mounted on a tripod, and manual mode so as to control the massive amount of white going on.
