Bird Walks

Spring Migration Bird Walks

Spring is an exciting time to go birding in Connecticut, as many species move into and through the state from wintering grounds further south.

The diversity can be overwhelming,  especially when identifying warblers high in the canopy or picking out songs in the dawn chorus. 

Join one of our spring migration walks to learn all about our spring migrants in some of the best birding spots in the southeastern part of the state! $10 for members; $15 for members. Space is limited to 12 participants. 

Masks are required and social distancing guidelines will be followed. 

The RTPEC frequently uses open space and land trust properties that are open to the public without fee.  The land trusts permit our use of these properties and receives no part of any fee collected by the RTPEC.

Webinars via Zoom

Rare Birds of Connecticut Webinar

Wednesday, April 28; 6 p.m.

California Gull at Hammonasset.

Well over 400 bird species have been recorded in CT. Of those, over a quarter of them are rare, sometimes only having been spotted once or twice in the state. Where did these birds come from, and why are they here? In this webinar, teacher naturalist Joe Attwater will go over the species that cause birders in the state to drop what they’re doing and grab their binoculars.

Joe will discuss:

  • How rare birds end up in CT
  • Rare species that have been seen in the state
  • How to find these rare birds

Program is free, suggested $10 donation
