July in East Africa. It's mid-winter in Arusha National Park at three degrees south and more than a mile above our warming oceans. We're experiencing mornings that do feel chilly right enough. Such that both locals and residents would really appreciate a wind-proof fleece. This past week I've been busy in the cool; early birding with overseas visitors; and local bird-guide training. Spending the chilly early mornings in the misty evergreen forests of Arusha National Park on Meru mountain side. And the warmer afternoons out in dry and dusty Meru-Maasai country, across the northern plains that mantle the national park's perimeter.
