Yesterday morning, twelve of us braved the foggy chill to look for birds near the Westinghouse Fountain at Schenley Park.

My original plan was to walk on the Steve Falloon Trail but it was a sea of mud after so much rain. Instead we walked along the Serpentine Road with a good view of the treetops.

The birds weren’t particularly active so we were happy to see these Best Birds: blackpoll warblers, chestnut-sided warblers, an eastern wood-pewee, scarlet tanagers and Baltimore orioles. We also saw a half-completed Baltimore oriole nest hanging from a branch high above the road.

At the end of the walk we stopped near the Schenley Park Visitors Center and on Flagstaff Hill to see two peregrine falcons (flying and perched at the Cathedral of Learning), a red-tailed hawk, and a Coopers hawk.

Thanks, everyone, for coming out on a gray day.

Lady Slippers In A Cage

This flower is in a cage at Ohiopyle State Park.

Pink lady’s slipper (Cypripedium acaule) orchids are found in Pennsylvania, but increasingly rare because deer like to eat them. The deer bite off the flower, leaving the stem and leaves behind.

Here’s what the entire flower looks like. Imagine it with a headless stem!

And here’s how these beautiful flowers are protected: a deer exclosure. Notice the 10-foot high fence with the yellow X. The sign explains why the exclosure is necessary.

Outside the fence I found five lady’s slippers with the chopped off heads. 🙁

We humans are the reason why there are too many deer in Pennsylvania and, so far, we haven’t the will to reduce their population to a sustainable level.

In the meantime we’re putting our most precious wildflowers in cages.

Why Wild Geranium is Called Cranesbill

North America’s wild geranium (Geranium maculatum) is also called cranesbill but you have to examine a seed pod to find out how it got the name.

Shown above is a wild geranium flower with some aging seed pods in the background. Here’s a closeup.

Notice that the seed pods look like a crane’s bill. (Click here to see a crane with its bill up like this.)

The Blue Jay’s Many Sounds

20 May 2016

Blue jays are making interesting sounds and gestures lately but what do they mean?

In the spring I often hear blue jays say “tweedle” and, on rare occasions, I see one bounce and gurgle.

Tweedle? Gurgle? Lesley the Bird Nerd explains it all in this video.

p.s. Only females make the “Rattle” call.

Now Blooming: Few-Flowered Valerian

This is a stellar year for Valeriana pauciflora at Raccoon Creek Wildflower Reserve in Beaver County, PA. Its common name is “Large-flowered Valerian” but its scientific name means “Few-flowered.” Confusing!

To find this 1.5-3-foot tall wildflower, walk the Jennings Trail between the two Beaver Trail intersections (along the cliff) or visit the spot where Jennings meets Meadow Trail and the creek. Click here for a map.

Read more about its confusing name in this Throw Back Thursday article: What-Flowered Valerian?

Visit the Wildflower Reserve soon to see it.

Messy Nest

In years past, Pitt peregrine watchers were used to seeing a very messy nest on camera. Dorothy, the previous resident female, usually plucked prey at the nest soon after she was done brooding. In those years the nest normally looked like this.

This year the nest has been amazingly clean … until yesterday. At 6:45am Terzo brought a black-feathered prey item to the nest. Hope took it from him and plucked it while C1 watched. (It was a male red-winged blackbird.)

I finally figured out there’s a good reason for making a mess. C1 will soon be old enough to eat on his own and will need to know how to pluck prey and tear it up. The best way to learn is by watching. Yesterday Hope showed him by example.

By the end of the month C1 will be grabbing the food and plucking it himself. In the meantime I’m sure he’ll watch more food preparation demonstrations.

Breakfast is served.

More Robins, Fewer White-throated Sparrows

18 March 2016

We humans are starting to respond to climate change. The birds already have.

In a study on two continents — North America and Europe — data from 1980 to 2010 shows that populations of our common birds have been affected by climate change and the gap is growing. Bird species expected to do well due to climate change have substantially outperformed those expected to do badly over the 30 year period. It’s the first real demonstration that climate is having a similar, large-scale influence on the abundance of common birds in widely separated parts of the world.(*)

Here are two examples from North America:

American robins (Turdus migratorius) are an adaptable species whose range has expanded as the climate warms. Robins don’t have to go as far south in the winter and now they breed in Alaska.

White-throated sparrows (Zonotrichia albicollis) are a common winter species in the Lower 48 but when it comes time to breed they’ll be in trouble. As the climate heats up and they move northward, the forest they require for breeding gives way to treeless landscapes such as tundra. It takes decades to grow a forest and the climate is changing faster than the plants can catch up. White-throated sparrows are losing ground. Click here to see their changing map.

More robins, fewer white-throated sparrows. The populations of common birds are affected by climate change.

Read more about the study here in Science Daily(*). See Audubon’s climate website for details on North American birds.

He’s Grown A Lot In One Week

C1, the lone chick at the Pitt peregrine nest, is eating well and growing fast. Here’s how much he’s grown in one week: May 8 to May 15.

Jungle Animal Hospital, PBS NATURE May 18

May 16, 2016Books & EventsKate St. John

There’s a hospital in the Guatemalan jungle that’s saving lives every day. It’s operating at capacity with over 700 boarders yet it tries not to turn anyone away. The hospital is ARCAS. Their patients are injured and orphaned jungle animals, often harmed by the illegal pet trade.

In PBS NATURE’s season finale, Jungle Animal Hospital shows the daily challenges faced by ARCAS staff as they heal the animals and prepare them for release in the wild. Every release is a celebration.

Some animals are so rare that each life represents a significant portion of the population. Such is the case with the scarlet macaws.

There are only 300 of these scarlet macaws left in the wild so ARCAS has developed a captive breeding program, similar in concept to North America’s peregrine recovery program two decades ago. The difference is that scarlet macaws are social animals so they must be reared and released in a flock with their friends.

Watch at the end of the show as ARCAS releases nine scarlet macaws into the jungle — 5% of the wild population — a moment so moving it brought tears to my eyes.

Don’t miss PBS NATURE’s season finale Jungle Animal Hospital this Wednesday May 18, 2016 at 8pm EDT/ 9pm CDT on PBS. In Pittsburgh it’s on WQED.
