Green-crowned Brilliant (Heliodoxa jacula)
Here is the Green-crowned Brilliant (Heliodoxa jacula), a large hummingbird commonly found at higher elevations in Costa Rica. It can be seen on edge clearings and in the forest, protecting certain feeding plants. This is an adult male, as juveniles usually have a mix of green and white plumage with a orange gorget. It turns purple as it ages, and as you can see by the full purple gorget this is indeed an adult male.

Our friends at the Chautauqua Lake Snowmobile Club have this NOAA/NWS snow depth map regularly updating on their website to let members and the visiting public know how much snow is on the ground in Chautauqua County. While it has gone down a bit recently due to a brief warm-up (very brief, and I am being very generous in saying “warm-up”!) and some rain, freezing rain, and sleet, there is still a ton of snow covering the earth in the region. You can see the escarpment well in this photo and the effect of elevation on snowfall and temperature. It will be utterly frigid later this...

As thunderstorms are impacting us here in Chautauqua County on the edge of a strong cold front birds are in flight on the cooperative northerly flow in its wake. The roughly circular areas of green are all avian targets being picked up by radar stations behind it. They appear centered only because the EM pulse rises as it moves away in all directions from the radar and most birds are flying a few to several thousand feet up. The hole in the middle is the cone of silence as the pulse does not go straight up and is sent out at a low altitude. In reality birds are flying everywhere in those...
