About Isaac Grosner

Originally from Massachusetts, Isaac has always been deeply interested in nature and the outdoors. This interest led him to pursue a bachelor’s degree in wildlife biology from the University of Vermont, where a course in Field Ornithology got him hooked on birds. An avid birder ever since, Isaac has lived and worked all over the country studying birds, from Golden-cheeked Warblers in Texas and Snail Kites in Florida to trapping and banding migrating raptors in the mountains of Idaho, along with many other avian research projects in between. These experiences allowed him to study birds across the country and develop a deep appreciation for North America’s incredibly diverse avifauna.

Wanting to learn even more about birds, Isaac earned a master’s degree from Southern Illinois University, where his thesis research focused on community ecology and grassland songbirds during the nonbreeding season. He presented his research at numerous local and national conferences, always eager for a chance to talk about birds. During this time, he also participated in many Christmas Bird Counts, Spring Bird Counts, and surveys for rare birds in Illinois.

Now settled in Connecticut, Isaac is eager to show people that New England is one of the most underrated regions for year-round birding in the United States. Home to an incredible diversity of breeding warblers in the spring and summer, impressive raptors, sea ducks and winter finches during the winter, and spectacular spring and fall migrations, the region offers exceptional birding throughout the year. Isaac is particularly fascinated by the spectacle of bird migration, especially when he gets to spend the day atop a mountain watching hawks streak past. He is also fond of seawatching, high-elevation birding in the mountains of Vermont, New Hampshire, and Maine, and combing through a variety of habitats in search of target birds.
