(If you subscribe to PABIRDS you saw this news over the weekend.)

After the great horned owl fledgling was rescued in Schenley Park on Tuesday March 29 and an adult was seen nearby on Thursday morning, I made it my mission to find the nest.  At first I came up empty.  There were no big stick nests in any of the hillside trees.

Then, late Friday afternoon I took another look at the underside of the Anderson Bridge.

Faintly through the trees I saw two owlets walking on a girder!

On Saturday I brought my scope and discovered that the “branching” owlets and their mother were quite visible from the Junction Hollow Bike Trail below the bridge.  Here are two (lousy!) photographs I took through my scope.

Above, mother owl and one owlet pose on the girder.  Below, the second owlet is perched just below the nest. Later he flew from girder to girder and landed near his mother.  The blue box highlights him in the washed-out photo.

On Sunday I visited the trail again and Nathan Mallory used my scope to take this photo of the two owlets sleeping.  You can see their stick nest above them on the lattice.

So there were three owlets in this nest. The first is in rehab.  The other two will probably fly soon.

 

 

p.s. As you can see, the Anderson Bridge is very rusty!  It will be completely replaced in a few years, after the Greenfield Bridge is done.

New Arrivals This Week

Brown creeper (photo by Steve Gosser)

Brown creeper (photo by Steve Gosser)

The flowers are ahead of schedule and so are some migratory birds.  This week in Schenley Park I found four new arrivals.

Brown creepers (Certhia americana) spend the winter in the central and southern U.S. so they know about our warm weather and can decide to migrate early.  I saw several brown creepers and heard their high pitched, squeaky song along the Bridle Trail on Thursday.

 

Two very tiny birds, smaller than chickadees, arrived on Tuesday. It’s unusual to see them together.

Golden-crowned kinglets (Regulus satrapa), at left below, have a winter range similar to the brown creeper’s and usually migrate through before their ruby-crowned cousins show up.  I found both birds on March 29 when I heard the ruby-crowned kinglet singing “Stay away!” as the golden-crowned chased him.  I’ve never seen these two species fighting!

Ruby-crowned kinglets (Regulus calendula) spend the winter in the southern U.S. and even in eastern Pennsylvania but they’re a big deal here.  An appearance on March 29 is two weeks earlier than I expect them.

Here’s the ruby’s song and, at the end, the “chack” he makes when annoyed.

 

On Tuesday I heard a lone chipping sparrow (Spizella passerina) along the Bridle Trail but couldn’t find him for two days.  He was hanging out with a flock of dark-eyed juncoes.  Bob Machesney says that in the North Hills the dark-eyed juncoes are gone before the chipping sparrows arrive.  This solo bird isn’t playing by the rules. 😉

Here’s the chipping sparrow’s song:

 

Watch for the first three birds in the days ahead.  Only the chipping sparrow will stay to nest in Schenley Park.

Schenley Park Last Week

Spring is early, as expected, so I wasn’t surprised to find leaves unfurling in Schenley Park last week.  Here are a few highlights from my walks in the past nine days.

Above, coltsfoot (Tussilago farfara) began blooming on March 7 and was still flowering when I passed by on March 24.

Below, Ohio buckeyes (Aesculus glabra) are one of the first trees to leaf out in Schenley Park.  These leaves picked up fluff from other trees whose flower parts had blown away, perhaps a wind dispersal strategy.  The buckeye makes flowers that attract bees.

Purple deadnettle (Lamium purpureum) began blooming March 10 and will continue for many weeks. Its flower has a spotted lip that says, “Land here, little insect.”

Happy Easter!

Seen in Schenley Park This Week

Flowers, birds, and too many deer, here are some sightings from Schenley Park in this week’s abnormally warm weather.

Red maples and American elms are blooming and bush honeysuckles are opening their leaves.

Above, these yellow flowers are beautiful on a large ornamental shrub but I can’t identify it.  Do you know what it is?

Below, our days are sometimes graced by a roosting eastern screech-owl.  I saw him on Thursday but he’s often not there.  Benjamin Haake was lucky to photograph him.

A decade ago deer were rare in Schenley Park but their population doubles every two to three years (yes, it doubles) and it’s taking its toll.  This week I walked by the golf course and noticed these arborvitae trees are naked from the ground to the height of a deer.  The browse line indicates there are now too many deer in Schenley Park — more than the land can support.

And finally, this plant is blooming in Schenley but also in lawns and waste places.  From long experience I know it’s hard to identify (and photograph).  Hairy bittercress (Cardamine hirsuta) is a non-native that’s not in many field guides. Click here to learn more about it.

p.s. Adam Haritan suggests that the yellow flower is Cornelian cherry (Cornus mas). That’s what it looks like to me (Click the link to read more and see a similar photo.)

Mud Season

Daffodil leaves, 3 Feb 2016 (photo by Kate St. John)

In this weirdly warm winter all the snow melted a week ago, the daffodil leaves poked out further, and we didn’t have to wear jackets.  At 61o on January 31 it was 26 degrees above normal!

Though yesterday’s temperature was exactly on target, today will be 8 degrees above average.  That’s not a huge difference but enough to maintain our early mud season.

We already had mud in our neighborhood ballpark when rain on Wednesday morning enhanced the creamy mudscape.

Off the beaten path at Schenley Park it was muddy too, though navigable.

It’s Time To Pick Up The Pieces

I don’t usually write about bridges, but there was big excitement only 1,200 feet from my house yesterday when contractors blew up the Greenfield Bridge.  As you can see from the photo above, it connected my neighborhood to Schenley Park (right of photo) over the Parkway East I-376.  I haven’t been able to walk into this part of Schenley since the bridge closed on October 17.

Even if you don’t live in Pittsburgh, the implosion made national news so you probably saw videos on TV.  Here are some photos of the event, a bit of the birds’ perspective, and links to my favorite implosion videos.

Above, a birds-eye view of the bridge on Christmas Eve.  Below, the bridge is wrapped, charged and waiting on Monday morning, December 28.

The implosion required a lot of warning, coordination, street blocking and police patrols.  The map below shows the exclusion zone.

Folks could stay home if their house was inside the circle but they had to stay inside and away from windows.  If you live that close to something this exciting, you either left home to watch nearby or you saw the best view of all on TV.

My house is outside the circle but I watched from one of the red roads closed to traffic. Those roads have good views but were open only to pedestrians to prevent gawkers’ cars from causing traffic and parking problems.  It was fun watching with the neighbors.  We were all in a party mood.

Starting an hour+ before the blast an infrared sensing helicopter circled overhead to make sure no one was outdoors within the exclusion zone.  One guy snuck into the woods and had to be rousted out.  We never saw him but he delayed the blast 20 minutes.

Back in October the neighborhood held a party and raffled off a chance to push the plunger and blow up the bridge.  Sally Scheidlmeier, pictured below, won that honor.  Here she is with the plunger (“Let’s Do It”) and the plunger’s victim in the distance, only minutes before the blast.  She pushed the plunger …

… and then …

Here’s my favorite video of the blast from the Post-Gazette.  Watch for the guy in the hard hat and orange-yellow vest who runs into the picture and down the road.  That’s a man who loves his job!

 

Down in The Run (the neighborhood in the valley on the left side of the exclusion zone), Trinidad Regaspi took a video with her cellphone.  Do you see that bird-like dot to the right of the telephone pole?  It’s one of four wild turkeys that flew across the valley to escape the noise.  They sure had a story for their friends last night!

… and then the bridge was gone.

It didn’t take long before the contractors were down on the Parkway picking up the pieces.  Six pillars on the Schenley side didn’t fall during the blast but they came down shortly after I took this photo at noon.  Alas, I missed it.

At road level there’s a lot of debris.

The contractors are out there picking up the pieces all day and all night (we can hear them).  They have to work fast because they only have permission to keep the interstate closed for 5 days after the blast.

I-376 is slated to reopen on January 1 at 6:00am.  The new bridge will take 18+ months to build.

Read more and see additional videos here at the Post-Gazette.

UPDATE DECEMBER 31, 2015:  The cleanup finished ahead of schedule!  The Parkway East opened INBOUND today at 2:00pm.  OUTBOUND will reopen between 10:00pm and midnight because of another project down the road at the Birmingham Bridge.

Look Down, Look Up

Oriental bittersweet hulls on the ground (photo by Kate St. John)

This month in Schenley Park I noticed lots of yellow hulls on the ground. Somewhat like pistachios, they were smaller and brighter with a ridge inside instead of on the edge.

Here’s what I saw when I looked down.

Oriental bittersweet hulls (photo by Kate St. John)

 

The hulls came from somewhere so I looked up to find the source:  Oriental bittersweet.

Each berry was encased in a three-part pod that burst open to reveal the fruit.  You can see three faint lines on the berries where the ridges made impressions.

And there above me, quietly eating the berries, was a big flock of robins knocking more yellow hulls to the ground.

Keep looking up.  🙂

Invasive?

Published by under Plants,Schenley Park

Unknown plant. Is it an invasive? (photo by Kate St. John)

What is this plant? (photo by Kate St. John)

Here’s a plant that’s quite visible in my neighborhood this month. I don’t know what it is but I suspect it’s an alien and possibly invasive because it shows off a number of imported/invasive features.

  • Imported: Its leaves are very green, suggesting it’s winter light trigger expects a more northern location.
  • Imported: It’s still producing flowers in December, another indication that it believes winter hasn’t arrived.
  • Invasive: It grows in waste places, especially in disturbed soil at the edge of sidewalks.
  • Invasive: It can become very dense and take over the area where it’s growing.

Here’s a look at the arrangement of the stems.  Notice that they’re hairy.

And here’s the flower.  I forced this one open.

Do you know the name of this plant?  My guess is that it’s from Asia, perhaps Japan.

If you know the answer, please leave a comment!

p.s. Wow! You’re quick!  Fran, Carolyn and Doris have already identified it as common mallow (Malva neglecta) or cheeseweed.  Read the comments to find out why it has this unusual name.

p.p.s. Here’s the University of California’s Integrated Pest Management recommendation for this plant.

Giant Puffball

Published by under Plants,Schenley Park

Giant puffball mushroom in Schenley Park, 18 Oct 2015 (photo by Kate St. John)

Giant puffball mushroom, 18 Oct 2015 (photo by Kate St. John)

No, that’s not a soccer ball in the woods.  It’s a giant puffball mushroom.

Giant puffballs (Calvatia gigantea) grow within a few weeks to become 4″ to 28″ in diameter.  Really giant ones can be 59 inches across and weigh 44 pounds.

They’re edible while young (white inside), not edible when mature (anything but white inside; turns yellow then greenish-brown), and then they decompose. 

Don’t rush out there and eat one unless you know what you’re doing.  Here’s a video that describes how to identify and cook them.

Notice this mushroom’s size compared to the oak leaves.  I wonder how much larger it will grow.

Close by was an open one, perhaps broken by an animal.  It was still white inside.

I’d never seen giant puffballs in the city before but spied these during a long walk in my neighborhood last Sunday.

I left them where I found them.  I’m not so fond of mushrooms that I’d pick and eat wild ones on my own.

White Snakeroot + Schenley Walk Reminder

White snakeroot, flower close up (photo by Kate St. John)

White snakeroot, flower close up (photo by Kate St. John)

Schenley Park Walk:
Just a reminder that I’m leading a bird and nature walk in Schenley Park on Sunday September 27, 8:30am – 10:30am.

This time we’ll meet at Bartlett Shelter on Bartlett Street near Panther Hollow Road.  This is not the usual meeting place at the Visitor’s Center.

Click here for more information and updates if the walk must be canceled for bad weather.

White Snakeroot:
On the August walk we saw white snakeroot and we’re sure to see it this month, too.  At the time I called it tall boneset, a confusing alternate name.  What was I thinking?!  I should have used its most common name.

White snakeroot grows 1 – 5 feet tall with opposite, toothed, egg-shaped leaves and branching clusters of bright white flowers.  Each flower head is a cluster of very tiny flowers, shown above.

White Snakeroot in Schenley Park (photo by Kate St. John)

The plant is similar enough to boneset (Eupatorium perfoliatum) that it used to be in the same genus, but it’s been reclassified to Ageratina altissima.   To avoid confusion with unrelated boneset I’ll call it “white snakeroot” from now on.

Unfortunately “snakeroot” is confusing, too.  White snakeroot (Ageratina altissima) is not related to black snakeroot (Actaea racemosa, black cohosh).  Arg!

In any case, we’ll see it next Sunday.

UPDATE: 27 September 2015:  We were a small group but we saw some cool things including this Best Bird:  A red-tailed hawk hovered above Panther Hollow and then screamed in (silently!) with talons extended to catch something on the ground! But he missed it.  We weren’t in the line of fire but we were certainly impressed!
