24th Saw a Heteroxenicus at about 13500'. It had a nest, I think on a cliff. But the cliff face was with me, & frightened the bird.

Also a nutcracker at Simouari - here also quite a number of spine-tailed swifts, whopping birds, with a gray back.

Aethopyga ignicauda seen on S side of the Karkyu La.
T. affinis at Simouari. T. henrici not noticed.
