Hen Harrier Poems is Colin Simms` fifth collection with Shearsman, & his third devoted to poems on a specific species, following Otters & Martens (2004) & Gyrfalcon Poems (2007). Future plans include volume devoted to poems on merlins & on goshawks. Simms is a naturalist who has observed the harrier & its North American cousin, the marsh hawk, for decades; his poems fuse a rich Bunting-esque diction & sonority with a focused eye & imagination.
