After having a great opportunity to study an adult Gambel’s White-crowned Sparrow (Zonotrichia leucophrys gambelii) at Arlene Koch’s property last weekend near Easton, while also enjoying the immature Harris’s Sparrow there, I was interested to learn more about this western subspecies’ history in Pennsylvania and the mid-Atlantic. Gambel’s White-crowneds are essentially the western-Canadian counterpart of our more familiar Eastern birds … Read More

We are spoiled in the United States with many concentrated birding efforts taking place throughout fall and spring migration such as hawkwatches, seawatches, Big Sits, and other surveys which all help to pull in loads of data on bird numbers and distribution, but there are very few endeavors taking place in countries like Belize.

Anna FasoliBird Finding Tips, Bird Sightings, Birding, birds in flight, distribution, eBird, General News and Info, Migration, Photography, Rarities, Trip Reports2 Comments

Hurricane Sandy created perfect conditions for rarities to show up in Pennsylvania. I will admit I was skeptical of just how disruptive this storm would be. Hurricanes in the northeast tend to get exaggerated by the media, and they always seem to lose power quickly and break up once they hit land. But Hurricane Sandy was really the perfect storm; … Read More
