Spring birding events are happening across Maine. Here’s where to go.  

Now the fun begins, as many birds and quite a few birders return to Maine for the summer. It’s time to get organized.

Birding is generally a quiet, solitary pastime — a stroll in the park, a walk in the woods, a paddle in the marsh.

Penobscot Valley Audubon’s Neighborhood Bird Walks kick off May 6. There are 13 walks scheduled at birding hot spots in Greater Bangor throughout the month. These walks have been immensely popular since they began nine years ago.

The benefits are many. It’s a chance to walk with experienced local guides, finding birds you might otherwise overlook. You can start to associate specific species with their preferred habitats. It’s a great opportunity to learn and practice identification skills and gather tips from others. Many participants enjoy the social camaraderie of guided bird walks.

I will lead two of these morning walks and probably tag along on several others. I chuckle at how easy it is to find birds in May. I’ve done these same walks so many times over the years, I usually know where different species will be before I even arrive. It’s almost like cheating.

Penobscot Valley Audubon members have already received the walk schedule in the most recent newsletter. Nonmembers can find the schedule on the chapter website at pvc.maineudubon.org. The walks are free and open to all.

Morning bird walks are fun. But for a full weekend adventure, try a birding festival. There are four great festivals to choose from.

The Wings, Waves & Woods Festival occupies the third weekend of May. Most events occur in Stonington and Deer Isle. Highlights include a Sunday visit to the Atlantic puffin colony on Seal Island, preceded by a Saturday cruise around the islands outside Stonington Harbor. I’ll be one of the guides on both.

I must say I am particularly excited about the archipelago cruise. Last year was the first year we did it, and I was not prepared for how many winter seabirds were still loitering around the islands. The numbers and variety were astounding. This festival is ideal for seeing the overlap of Maine’s overwintering birds and newly arrived spring migrants, all on the same weekend.

The Downeast Spring Birding Festival spans Memorial Day weekend. I’m awed, or maybe odd, to say I’ve been guiding for this festival ever since it began in 2003. Indeed, I led the very first walk of the first festival. That was amazing enough to convince me to keep doing it for the next 23 years.

Cobscook Institute coordinates the festival from its campus in Trescott. Events cover birding hotspots in Washington County, Campobello Island in New Brunswick and nearby offshore islands. Two different boats will visit two different puffin colonies over the weekend.

I might get an argument from the organizers of other festivals, but I personally think this one is the birdiest for two reasons. Memorial Day weekend is about the time the last returning migrants pass through Washington County, adding to the number of songbirds that have already established breeding territories for the summer. The Cobscook Bay area also has some of the most diverse habitat in the state, creating opportunities to see a wide variety of species in a relatively compact area.

The Acadia Birding Festival is the granddaddy of them all. Now in its 27th year, it’s the biggest of Maine’s festivals and attracts nationally recognized guides and speakers. It offers the advantage of birding in and around Acadia National Park.

The official dates for the festival are May 28-31, but three pre-festival trips are offered: one to Monhegan Island, one to Saddleback Mountain near Rangeley seeking the elusive Bicknell’s thrush and one to visit the puffins on Petit Manan, with a second post-festival trip to Petit Manan also available.

And now for something completely different: The  Rangeley Birding Festival. The mountainous forests of western Maine host a different selection of bird species compared to the three coastal festivals. This is the realm of Canada jays, boreal chickadees, black-backed woodpeckers and that elusive Bicknell’s thrush.

By June 5-7, when this festival occurs, spring migration is over. Birds have settled into their nesting territories, where they can be predictably found. Very few organized events introduce birders to the boreal forest, so this festival has its own unique appeal.
