We will certainly see purple deadnettle.

A Symbiotic Relationship

Warbler migration is ramping up and we’re already craning our necks to see them.  Up to now it’s been easy to find birds in the leafless trees but that’s about to change.

In Schenley Park the box elders burst into flower and leaf last week (above), the Norway maples opened last weekend, and the oaks and hickories are blooming now.

Here’s a red oak twig on April 19 just before the buds burst.  Who knew they could grow so long!

Inevitably the warblers gravitate to the leafy trees where they’re hard to find, prompting the common complaint, “The leaves are hiding the birds.  I wish the leaves weren’t there!”

But if the leaves weren’t there, the birds wouldn’t be either.

Insects time their egg-hatch and larval growth to take advantage of leaf out.  These tentworms appeared in Schenley Park when the choke cherries opened their leaves.

Leaf out brings insects.  Insects bring warblers.  It’s a symbiotic relationship between birds and trees.

The trees are probably happier than we are to see the warblers arrive.

This Morning in Schenley Park

Ready for a walk in Schenley Park, 29 March 2015: Diane, Jen, Rachel, Missy, Jen, Hayley, Julia, Rosie (photo by Kate St. John)

Nine of us braved the cold this morning at the Bartlett Shelter in Schenley Park.  We didn’t see anything blooming in 20F degrees but it was sunny and the birds were active.

We saw three Best Birds:  a fox sparrow sunning himself by the stream, a golden-crowned kinglet flitting in the treetops, and a male pileated woodpecker hammering a dead branch (unusual for Schenley).  I checked my records for the fox sparrow. He’s the earliest I’ve seen in Schenley Park.  They always arrive alone — usually April 4 to 9.

Here are the birds we saw and heard:
* Red-bellied Woodpeckers
* Downy Woodpeckers
* Northern Flicker (heard, not seen)
* Pileated Woodpecker, unusual in Schenley Park
* Blue Jays, abundant and loud
* American Crow, flyover
* Carolina Chickadees
* Tufted Titmice
* White-breasted Nuthatches
* Golden-crowned Kinglet, 1
* European Starlings
* Fox Sparrow, 1 by the stream
* Song Sparrows, singing
* Dark-eyed Juncoes, singing
* Northern Cardinals, singing
* Common Grackles
* House Finches

I’m so glad we went out this morning!  If I hadn’t promised to be there I would have missed that fox sparrow.  :)

 

The next outing will be Sunday April 26, 8:30am.  Meet at the Schenley Park Visitors Center (near Phipps).  Check here for details as the date approaches.

Here’s a Monday quiz to exercise your brain.

I found this miniature mesa in Schenley Park last week.

Do you know what it is?

Which side is up?

Here’s a more complex formation.

It Was Pretty

Yes, last Thursday’s snow was pretty.

It coated the trees like a winter wonderland outside John English’s apartment window (above).

And I found close up beauty in Schenley Park.

In December I’d be thrilled by snow but within a few hours I was heartily tired of this beautiful event.

Fortunately it will go away this week.

Coming Soon: Spring Walks in Schenley Park

Spring is coming next month and when it does, let’s go outdoors!

From March through June I’m leading bird and nature walks once a month in Schenley Park.  Come out with me to see birds and blooms, trees and bees.

On each walk we’ll travel at the speed of botany (slowly!) keeping our eyes and ears open for the latest flora and fauna.  Dress for the weather and wear comfortable walking shoes that aren’t afraid of mud.  Bring binoculars and field guides if you have them.  The walks will last two hours, but you can bow out early.

Here’s the schedule:

As each date approaches I’ll post a reminder on the blog — or visit my Events page any time for directions and up-to-date information including cancellations and rain dates.

Hope to see you in Schenley Park.  I can hardly wait for Spring!

Black Gray Squirrels

Published by under Mammals,Schenley Park

Throw Back Thursday (TBT):

Last month when the leaves changed color I began to notice the many black squirrels in Schenley Park.  During the summer they were hidden by leafy shadows but they stand out now among the bare trees and fallen leaves.

Black squirrels aren’t a separate species.  They’re just “eastern gray squirrels” (Sciurus carolinensis) that are melanistic.  This one isn’t 100% black.  He has white whiskers.

Read more about melanism and squirrels in this article from 2010 entitled This Is A Gray Squirrel.

Witch-hazel Blooming

Witch-hzel blooming in Schenley Park (photo by Kate St. John)

American witch-hazel (Hamamelis virginiana) is blooming in southwestern Pennsylvania.  Look for small yellow flowers clustered on the stems of a shrub or small tree.

Its four petals resemble lemon peel and are slightly hidden by the leaves right now but they’ll persist into November when they’ll be easier to see.

Witch-hazel is the only tree I know of that blooms in the fall, September to November.  It has other odd traits, too.

  • Though it blooms in the fall, it doesn’t set fruit until the following August, nearly a year later.
  • Just before it blooms the old fruit explodes, dispersing seeds up to 20 feet away.
  • Witch-hazel can find water. Its branches are used as divining rods.
  • It’s no coincidence that this plant has the same name as the astringent “witch hazel.”  The topical treatment is an extract of witch-hazel’s leaves and bark.

I found this one blooming in Schenley Park along the Lower Panther Hollow Trail.

International Rock Flipping, Without A Flip

International Rock Flipping Day logo (from Wanderin' Weeta)

Today is International Rock Flipping Day and I’m participating for the sixth time in this Blog Carnival event.

But the truth is I did not flip a rock.

This year I finally realized that I don’t like to flip rocks.  I don’t want to be surprised by what’s underneath and the surprise is increased by having to stand close enough to photograph the critters.

Before this dawned on me I flipped two carefully chosen benign-looking rocks.  Predictably, there was nothing but dirt under them.  (Whew!)  Even so I followed Rock Flipping Protocol and replaced the rocks as I found them.

Then I remembered Mainly Mongoose’s 2010 blog post in which she pondered the hazards of flipping rocks in the lowveld of northeastern South Africa, a location filled with poisonous snakes. Luckily she found a rock monitor (lizard) poised in a rock crevice.  No flipping required!

So I switched strategies and photographed the most interesting crevices in the rock walls at Schenley Park.  This yielded three spider webs: a many-round-holed web, a hammock, and a funnel.  The spiders were quick to hide as I approached.

Hoping for more interesting creatures, I visited the groundhogs’ wall domain but no one was home until this little guy appeared, hidden behind the flowers.

Not as good as a rock monitor but a chipmunk is a nice surprise.

Happy, International Rock Flipping Day.  Go out and flip a rock if you dare!  Remember to put it back the way you found it.

 

p.s. Heather Mingo At the Edge of the Ordinary posted links to 2014’s hearty crew of international rock-flippers.  Click here for the round-up and links to the flipper results on Flickr and Facebook, too.
