What to Expect in Early May

Published by under Phenology

The beginning of May is a birder’s paradise. Spring migration hits full stride.  Of course there are great birds at the “hotspots,” but unexpected species may stop in your backyard on their way north.

Here’s just a taste of the excitement in early May:

  • The trees leaf out and our brown, sun-filled forests become green and shady almost overnight.
  • Birds arrive in many colors:
    • Bright red, orange, black and blue:  scarlet tanagers, rose-breasted grosbeaks, Baltimore orioles, indigo buntings.
    • Shades of brown: hermit thrush, Swainsons thrush, wood thrush and veery.
    • Yellow and green:  Warblers and vireos galore!  The yellow warblers and yellow-rumped warblers we were happy to see in April will seem boring in May.
  • Nesting is happening everywhere.  Watch for the first robin fledglings.
  • More flowers bloom:  Jack-in-the-Pulpit, Fairy bells, Bellwort, Canada Mayflower and Mayapples.
  • More moths and butterflies appear.
  • And you’ll see the first baby bunnies.

Take part in some outings to see the sights of May.

False Miterwort

Published by under Plants,Schenley Park

Foamflower blooming (photo by Kate St. John)

Foamflower is one plant, Miterwort’s another, but I called a patch of Foamflower “Miterwort” during last Sunday’s outing in Schenley Park.

Perhaps that’s because one of Foamflower’s alternate names is “False Miterwort.”  I must have had that in mind when called it Miterwort. (Sure!)

The position of their leaves is the easiest way to tell the difference.  Though the leaves are the same shape, Foamflower has basal leaves, Miterwort has two leaves opposite each other in the middle of the stem.

A close look at the flowers also tells them apart. Foamflowers (Tiarella cordifolia) look fluffy or foamy (first photo).  Miterwort (Mitella diphylla) flowers have intricate lace edges like tiny bishops’ caps — or miters (second photo).

I know the difference but I persistently say the wrong name.

Maybe I’ll do better now that I’ve publicly embarrassed myself.  😉

p.s. Since last Sunday the deer have eaten the tops off half of those Foamflower plants.  Grrrr!

For These Eagles, A Much Better Year

Nothing’s been simple for the bald eagle pair at the Norfolk Botanical Garden (NBG), right down to the fact that they don’t nest at the Garden any more.

As one of the first bald eagle pairs to have their own webcam the NBG eagles were well watched and now loved by people around the world.  Their nesting seasons have had many ups and spectacular downs, particularly in 2008 when they had a Peyton Place event, two nest failures, and their third try ended with an eaglet who caught avian pox.  Buddy‘s beak was deformed so badly that he could never fly free.

Life was good again until their nest site became a problem in 2011.  Norfolk Botanical Garden is on the edge of Lake Whitehurst and surrounded on two sides by Norfolk International Airport. Bald eagles and airplanes occasionally share space.  This was fatal for the female eagle in late April when she landed on the runway and was killed by an airplane.  Concern that the male could not feed the chicks without her help prompted their removal from the nest to a rehab location where they were raised until they fledged.  It was a very bad year for the eagles.

Things got worse.  The female’s death underlined the dangers of the birds’ proximity to air operations so in 2012 U.S Fish and Wildlife told the City of Norfolk that the eagles’ nest had to go.  The male had found a new mate, but every time they built a nest USDA removed it.  Eagle lovers formed Eagle On Alliance and filed a lawsuit to protect the eagles from harassment. Ultimately USDA removed nine nests.

This year the NBG eagles took the hint and moved out of harms way to the other end of Lake Whitehurst.  Their new nest is on private property, far enough to satisfy the FAA.  They don’t have a webcam but Eagle On Alliance obtained permission from the landowner to photograph and film the eagles.

The pair has hatched one or more chicks and is currently raising a family.  Peek between the branches in Mike Inman’s photo above and you’ll see a hungry eaglet.  This has been a much better year!

Follow the the NBG eagles on Facebook at Norfolk Botanical Garden Eagle Alliance.

Nest Box Competitors

Published by under Nesting & Courtship

Carolina Chickadee (photo by Cris Hamilton) and House Wren (photo by Chuck Tague)

Last week in Schenley Park I watched a house wren claiming a nest box at the golf course.  While the wren sang near the box, a Carolina chickadee peered out of the hole.  One of them was going to win the box.  My bet is on the house wren.

Good nest locations are highly contested both within and between species.  Chickadees, house wrens, bluebirds, tree swallows and house sparrows all compete for the same nest boxes.   The winners are determined by timing, temperament, and weaponry.

Chickadees are brave but small. They usually lose.

Eastern bluebirds and tree swallows are well matched and can share the same territory if two nest boxes are placed next to each other.  The bluebirds begin nesting earlier and pick a box. The swallows arrive later and pick the other.  But it can go either way.

House wrens don’t need to nest in boxes but when they’ve picked one they are persistent, quick builders and will remove the eggs and very young nestlings of other birds.  They trump the other three.

By law you can’t interfere with these native species but you can put up more boxes.  The wider the selection, the less they’ll compete.

House sparrows are another story, though.

Aggressive and well armed, house sparrows always win. They claim several boxes even though they use just one.  They kill the nestlings and even the adult bluebirds incubating eggs.  The only way to protect bluebirds is to trap and kill the house sparrows.  You can to do this because house sparrows aren’t protected by law.  They’re “listed” as an invasive species.  (Click here to read more at the bluebird website, sialis.org.)

In the city there’s cruel justice for house sparrows.  When another invasive species wants their nest they’re out of luck.  The starlings win.

Winter Leaves Its Mark On Spring

What a slow spring!  Last week it snowed in western Pennsylvania.  With an inch on the ground in Du Bois, Marianne Atkinson noticed that the forsythia blossoms stood out but they looked very odd.

In her own yard the forsythia had flowered near the ground but the top looked dead. Did other shrubs have this problem?  As she traveled around town she took photos of other forsythia bushes and discovered that all of them looked like this.  The buds on top were winter-killed.

Why were the bottoms of the bushes OK?  With a little research Marianne found:

We had a second very cold winter in a row, with occasional temperatures in the well below 0 range.  We also had about 18 inches of snow cover for about 2 ½ months this winter. I thought that the snow cover may have acted as insulation for the lower forsythia flower buds and it is true! You can read about this phenomenon in the links below:

Why are trees and shrubs so slow to leaf out this spring?

How cold was it?  Here’s a photo of last winter’s record in Marianne’s backyard.  -19 degrees Fahrenheit!

April 26 outing in Schenley Park (photo by Kate St. John)

This morning there were eight of us on the Schenley Park outing:  Linda, Larry, Michelle, Rose, Jen, Marianne and Dave. (Dave missed the photo opportunity & I’m behind the camera.)

At the Visitors Center we saw Virginia bluebells and redbud blooming.  In the creek valley we found miterwort, yellow trout lilies and large-flowered trillium.  We did see purple deadnettle, as promised.  😉

In addition to the usual residents we saw these Best Birds and bird behavior:

A good time was had by all.

Watch for my next outing on the last Sunday in May — May 31.

Look But Don’t Touch

Published by under Insects, Fish, Frogs

Oil beetle of some sort, 19 April 2015, Linn Run State Park (photo by Kate St. John)

This indigo-colored beetle looks beautiful but I was careful not to touch him last Sunday at Linn Run State Park.  It’s a good thing I didn’t … and here’s why.

At an inch and a half long this beetle was hard to miss. Thirteen of us watched him walk on the leaves.  Loree Speedy suggested he was a Blister Beetle.

Wissahickon‘s bug expert, Monica Miller, confirmed he’s one of the many species of Oil Beetles (Melos) in the Blister Beetle family (Meloidae).  His true identity requires a coleopterist’s help but her guess is Meloe impressus.  (I like the idea that “This Meloe impressed us.”)

Blister Beetles earned their name because they excrete a poisonous chemical from their leg joints, cantharidin, that causes blisters on our skin.

Yes, he’s an amazing color, has short wing covers, knobby antennae.

Curiouser and Curiouser

Published by under Peregrines

Peregrine dozing high on the Westinghouse Bridge, 12 April 2015 (photo by Dana Nesiti)

Identifying this peregrine falcon at the Westinghouse Bridge is a lot harder than we thought.

Thanks to Dana Nesiti’s many fine photographs, we were fairly sure in mid-April that the Black/Green bands were 66/C.  If so, it meant Surprise! the female “Storm” from Canton, Ohio had re-won her old nest site.

But we weren’t sure.

On April 18 John English, Dana Nesiti, and Maury Burgwin made another visit to the Westinghouse Bridge armed with cameras.  Using Dana’s new photos of the bands we were ready to declare this bird is 68/C, a female named Blaze hatched at the Bohn Building in Cleveland in 2005.  However, Anne Marie Bosnyak’s online investigation found that Blaze died in a territorial battle in Michigan in 2008.  This bird cannot be Blaze.  The bands aren’t 68/C. (See the comments on who she was probably fighting!)

So who is this bird?

We know that the 50-60/C series is a large band normally used on female peregrines so this bird is female … right?

Maybe not.  PGC’s peregrine coordinator, Art McMorris, suggests the bands could be 58/C, a male named Mike hatched at the Mendota Bridge in Minneapolis, Minnesota in 2004.  Sometimes a male receives the large-size band on banding day.

The peregrines’ behavior at the Westinghouse Bridge says that incubation started on Easter Sunday April 5 so it makes sense that the male would be standing guard now (or sleeping) while the female incubates.  The female could still be Hecla (Black/Red 68/H).

The plot thickens.  We need more evidence.

As John English said on Pittsburgh Falconuts Facebook page, it’s “Curiouser and curiouser … Westinghouse Bridge continues to confound and really needs more than just three observers.”
