Olive sided Flycatcher

This compact, big-headed flycatcher sits bolt upright on top of the highest dead branch of a tree, calling pip-pip at intervals, as if to ensure that birders notice it. A long-distance migrant, the Olive-sided Flycatcher breeds mostly in northern coniferous forest and winters in the tropics. It has become noticeably less common in recent years, perhaps because of a loss of habitat on the wintering grounds.
