New video Red Knot & Gulf Grunion | Aves UABCS & Pronatura Noroste

Gulf grunion eggs are the most important food source for Red Knots roselaari during spring migration at Golfo de Santa Clara, of comparable ecological importance to to horseshoe crab eggs in Delaware Bay (Hernández-Alvarez et al. 2013). The Laboratorio de Aves UABCS and Pronatura Noroeste have made a video about Red Knot and the Gulf Grunion in the Upper Gulf of California, Sonora (Mexico), that they are pleased to share with you:
