Looking over the meadow across from my house where he will feed, this male has a black band across his back which is the shadow of another powerline above him. 🙂 I’ve seen both male & female of these all over Costa Rica as shown in my gallery at: Blue-black Grassquit, Volatinia jacarina, including that first trip to Costa Rica while at Carate on the Osa Peninsula in 2009. Note that he is similar to the Blue-black Grosbeak I recently shared a photo of, but smaller. Both feed on the grasses (seeds).
¡Pura Vida!
