Problems with ID

Adrian and I were out birding here in Bahrain a few weeks ago with two visiting birders in tow on the Jebel Dakhan. Adrian photographed a Desert Lark, that I had pointed out. Yesterday he put the picture up on his photo pages and since I have received several emails to tell me that my ID is wrong and in fact the bird shown is a female Black Lark Melanocorypha yeltoniensis. The first two pictures are the two images as taken by Adrian - below are two further Pictures I took today of a Desert Lark on the Jebel. I am sticking to my original opinion Desert Lark - Comments please!

Desert Lark Ammonanes desert according to Nightingale and Hill (1993) Birds of Bahrain, the endemic A d insularis breeds Bahrain. Today I returned to the Jebel Dakhan in search of the dark lark but could only find our normal looking Desert Larks managing to get these two shots
