100. Bulwer's Petrel (Bulweria bulwerii)

Bulwer's Petrel is a moderately large petrel with loooong wings and a long tail usually held in a pointed shape, which can help distinguish it from the similarly dark but shorter-tailed Sooty Shearwater. It appears quite slim and small-headed with a shorter, thicker bill than the Shearwaters. It is widespread, breeding on islands in the Pacific and Atlantic including the Azores and Canaries, and wintering on the sea mostly around the tropics but as far north as the seas off Portugal in Europe.

Bulwer's Petrel sketch.

I chose a photo of a Bulwer's Petrel sitting down rather than one in flight to give myself a break from cocking up the proportions of birds in flight, well that was the plan (also there wasn't a huge range of Creative Commons-licensed photos!). I think it's come out slightly better than many of my recent efforts.
