Eastern Bluebird Breeding, All Is Well

Eastern Bluebird

It's that time of year, when birds are breeding everywhere. We get lots of questions about nesting birds, especially nesting bluebirds. People cherish their bluebirds and worry about the things they see their bluebirds do. For example, here's part of a recent question to us about bluebirds — "There have been 3 eggs in the box now for going on 2 weeks. I’m guess the eggs are not viable but momma is still in the box laying on them???? What to do?? Do I remove the eggs? Remove the whole nest? Just leave things alone? I think they’ve been there too long now to hatch – yes/no/maybe so?? Please advise."

The answer is that this is normal and her eggs will hatch soon. In most cases there is no cause for concern.

Here's some basic information about bluebirds to calm worries.

- Eastern Bluebird females build the nest out of fine grasses or pine needles and it can take as little as 2 days, but 4-5 days is the average. During courtship the male can feed the female and he may continue to occasionally bring her food during incubation.

- Once the nest is built, egg-laying can begin in a day or two' but may not begin until a week later or so. So don't panic if you see a built nest and no eggs right away, it does not mean the bluebirds have abandoned it.

- Females lay one egg per day in the morning and spend very little time at the box during egg-laying. The eggs can remain there at air temperature with no harm to them. So just because you see a nest and several eggs and no female, does not mean the nest and eggs are abandoned. She can lay 1-6 eggs in a clutch. If one or some of the eggs are infertile, but not the others, she may leave the infertile egg unhatched in the nest, or the parents may try and remove it. Bluebird eggs are blue but in 9% of the cases they have been found to be white.

- Only after the last egg is laid does the female do full-time incubation. She takes breaks every once in a while to go feed, preen, take a bath, take a break, etc. In warmer weather, she may leave the nest for longer periods of time. Incubation can last 12-18 days.

- After the eggs hatch both parents feed the young and remove the fecal sacs (little white diaper like sacs) from the nest. The parents feed each young about two times an hour, regardless of how big the brood.

- The length of time the young are in the nest for the Eastern Bluebird varies from 16-21 days. It is OK to look into the box once or twice a week to check on the progress of the bluebirds. Your scent on the box will not cause the birds to leave (most bird species have very little sense of smell). Do not look in the box once the young are 12 days or older as this may cause them to premature leave the box before they are ready.

After they fledge they will continue to be fed by the parents for another 3-4 weeks and by 5 weeks the fledglings have learned how to feed on their own well enough to be independent. The bluebird pair may start another nesting while they are still feeding young from the first brood. Bluebirds may have 1 to 3 broods per year depending on the area of the country they live in and other factors.

Migration in full swing

Rose-breasted Grosbeaks have arrived in many of the northern areas of the country. Migration is now in full swing or beyond with hummingbirds, warblers, vireos, thrushes, flycatchers, orioles and more all arriving on their breeding grounds. Enjoy the birds.

NH Audubon Birdathon

Participating NH Audubon Birdathon, a fundraiser for the organization. Just had a Pileated Woodpecker, Yellow-rumped Warblers are everywhere.

The Biggest Week in American Birding recap

 Here's the birders on the wonderful bird walk we led with Kenn and Kim Kaufman and best of all, the proceeds went to benefit Black Swamp Bird Observatory's outreach and education programs.

Birds and Blooms Magazine were sponsors of the bird walk. It's a beautiful magazine, you should check it out.

Blackpoll Warblers were frequently spotted.

Magee Marsh has a boardwalk that goes through a woodland area that is important stopover habitat for migrating warblers, many of whom are headed to their breeding grounds in the Canadian boreal forest. The boardwalk can get crowded with birders and photographers, but everyone is so nice and they all share space to view the warblers.

Large numbers of photographers were there with big cameras and long lenses, many standing at the woodland edge of the parking lot, before the entrance to the boardwalk.

We just got back from one of the best ever "The Biggest Week in American Birding" Festivals at Magee Marsh, OH, with fantastic looks at warblers. When we were asked by Kim Kaufman (who is directer of Black Swamp Bird Observatory, which sponsors the event, along with other important organizations) and Kenn Kaufman (super-famous, esteemed birder and field guide author) to be keynote speakers and to lead a fundraiser celebrity bird walk with them and do a keynote talk and book signing, we jumped at the chance.

We were at the festival from last Thursday to Sunday and could not have been happier. In addition to an incredible number of events like guided walks, bus trips, workshops, keynote speakers, evening socials, vendor marts, Optics Alley, chances to meet many wonderful birders and more, the real attraction was the large number of warblers and other birds who use Magee Marsh woodlands on the shore of Lake Erie as an important stop-over habitat. The Biggest Week Festival spotlights the importance of this valuable habitat and its role in bird conservation.

Kim and Kenn and the entire group of volunteers and sponsoring organizations did a fantastic job of putting on what is one of the premier birding festivals in North America. It brings together so many wonderful people, all there to celebrate and enjoy the birds. Most importantly, the birds are the real stars and their story of survival and arduous migration journeys is writ large as thousands of birders' eyeballs drink in the eye candy and appreciate these avian jewels. Thanks to all who contributed to the festival and a special thanks to Kim and Kenn as the dedicated conservationists and guiding spirits behind the festival.

The Biggest Week in American Birding is Going On Now, May 3-12th in OH, Come Visit

Bay-breasted Warbler is just one of the many eye-candy avian treats waiting for you at The Biggest Week in American Birding which is going on now from May 3rd to 12th at Magee Marsh, OH, the warbler capital of the world. We will see you there! We are giving the keynote address on Friday, May 10th. The Biggest Week is a mega-birding happening with lots of birders, guided walks, evening socials, lectures, workshops, events, field trips, birding celebrities like Kenn and Kim Kaufman, and tons of fun.

Magee is just an awesome place to see and photograph warblers because the birds are so close. Birders stand on the boardwalk that goes through the wooded area at the edge of Lake Erie, where all the warblers congregate. It seems like warblers are just dripping from the trees.

Magnolia Warbler is one of my favorites

Here's an American Redstart, male,

and a Black-throated Green Warbler

Blackburnian Warbler

If you are anywhere near northwest Ohio this week, then get yourself over to Magee Marsh and the festival. They are still accepting walk-in registrations at Maumee Bay Lodge and Conference Center  and Black Swamp Bird Observatory. We hope to see some of you there!

Guess Who?

Guess Who showed up in our NH yard today? "Weesee, weesee, weesee" it sang.

Eastern Towhee Birthday Bird

I had been trying to get a good photo of this Eastern Towhee, male, that has been newly hanging around our property, with no success. It has either been in bad light, hidden in shrubs, just flown by the time I got my camera, etc. you know how it is. This morning it hopped up on our bird bath right in front of our window and I got this shot. Yes! It's my birthday and I couldn't have asked for a better bird photography op gift.

Spring "To Do" List for the Birds

Ruby-throated Hummingbird

MIgrants are arriving all over the country. Baltimore Orioles and other orioles can be attracted with orange halves, especially when they first arrive from migration. Later, when they're nesting, they primarily eat insects.

Cardinals like to nest in dense shrubs.

Spring is here, so here's a few "to do's" to welcome the birds:

* Make sure all your bird houses are cleaned out.

* Put up new bird houses, since hole-nesting birds like bluebirds, chickadees, titmice, wrens, Tree Swallows, etc. are actively choosing houses now, plus there will be houses available for later arrivals.

* Try offering new foods, like mealworms, oranges for orioles, other fruit, jelly.

* Plant shrubs that provide nesting structure for birds such as lilacs, alders, dogwood shrubs, evergreens, willows, etc. Plant them in groups.

* Get up your hummingbird feeders now, (at the latest by Mother's Day if you live in the most northern sections of the country). Make sure to clean hummingbird feeders ever 2-3 days in hot weather.

* Plant red tubular flowers to attract hummingbirds, such as red salvia, red impatiens, trumpet honeysuckle vine, like Goldflame Honeysuckle (Lonicera heckrotii), trumpet vine (Campsis radicans), red bee balm, red fuschia.

* Plant composite-type perennials and annuals such as, Purple Coneflower and Rudbeckia, whose seed heads will attract finches and sparrows. Butterflies will come to Purple Coneflower when its in bloom.

* Make sure you have several bird baths filled with fresh, clean water all summer.

* Clean your bird feeder regularly with a mild bleach solution, rinse well. Keep them filled with sunflower, and quality mixes.

* Put a bench or adirondack chair in your backyard where you can sit with binoculars and enjoy the show. Get our new regional guides, The New Stokes Field Guide to Birds: Eastern and Western Regions to help you ID your birds. That could be your summer vacation.
