Blue-vented Hummingbird (Saucerottia hoffmani)

I found the Blue-vented Hummingbird in Monteverde, at Café Colibrí. It was not very common, arriving just once in a while, and at first glance I thought it was a Rufous-tailed Hummingbird or Coppery-headed Emerald due to its similarity. I was focused taking pictures of the glittering Violet Sabrewing, so did not spend as much time with this one as it deserves.
