Seen This Week: Ducks, a Swan and Leaf Out

30 March 2024

A Wednesday trip to Moraine State Park was cold and gray but quite worthwhile. We saw 300(!) red-breasted mergansers, many ring-necked ducks, blue-winged teal and a rare bird — a trumpeter swan. Charity Kheshgi’s photos show off the teal and swan.

Trumpeter swans (Cygnus buccinator) are “the heaviest living bird native to North America and the largest extant species of waterfowl.” They were nearly extinct in 1933 — only 70 remained in the wild — but several thousand were then found in Alaska. “Careful re-introductions by wildlife agencies and the Trumpeter Swan Society gradually restored the North American wild population to over 46,000 birds by 2010.” The trumpeter at Moraine is one of their descendants. (quotes from Wikipedia)

Spring is 20 days early in Pittsburgh this year. To prove it the yellow buckeye trees were in near-full-leaf on Thursday 28 March in Schenley Park.

They are 8 days later than the astoundingly early spring of March 2012. Click here to read about that year.

Early spring is the hungriest time of year for deer in Pennsylvania because they’ve already eaten all the easy-to-reach food. When the deer population is greater than the area’s carrying capacity they seek out food in unusual places. Thus I was amazed but not surprised to see a deer browsing the bushes next to our highrise at 5:30am. There is nothing to eat down there. There is nothing to eat anywhere near here.

Anhinga Shows How To Catch and Eat

Unlike herons, anhingas spear their prey but this means they can’t open their beaks to swallow. This video shows what they do to solve the problem.

p.s. There’s a bird in Africa that looks like an anhinga (Anhinga anhinga). Closely related, the Anhinga rufa is the “African darter.”

No Amount of Money Can Stop The Ocean

26 March 2024

A decades-old problem became acute his winter. After high winds and a historic high tide damaged 20+ beachfront homes in January at Salisbury Beach, Massachusetts, the residents took up a collection to build a protective dune. It took five weeks, 14,000 tons of sand and more than half a million dollars to build the dune to protect the homes. Three days later it was gone.

Completion of the dune project in early March brought high hopes to Salisbury Beach.

Facebook post by Salisbury Citizens for Change after the dune was completed on 6 March 2024

But in the next three days a natural occurrence, an astronomical high tide, washed it all away.

The temporary dune did it’s job — no homes were damaged in March — but the idea of spending half million dollars after every storm is out of the question. So the town is regrouping and weighing options.

You might be wondering: Why don’t they just build a seawall?

Seawalls just move the problem a few hundred feet down the beach so they are generally not allowed in Massachusetts (see special exception in yellow).

Also, a seawall will remove the beach entirely as shown in this diagram. If Salisbury Beach builds a seawall they will have no beach at all, just a wall with a sheer drop to the ocean. Understandably, the homeowners want a beach.

The ocean takes land slowly … and then all at once. No amount of money can stop it.

Yesterday at Duck Hollow

25 March 2024

Yesterday at Duck Hollow it was brilliantly sunny and *cold.* Though the temperature was 27°F the light wind made it feel like 17°F. Brrrr!

Charity Kheshgi and I scouted on Thursday and found a pied-billed grebe near shore who was still present in the same zone on Sunday. Alas, the seven horned grebes we saw on Thursday were long gone.

Despite the cold and (shall I say “stabbing”?) sunlight we had a good time and saw 32 species. Our checklist is here https://ebird.org/checklist/S165818025 and printed below.

How Do They Protect Their Babies?

8 March 2024

How does a bird that nests on lily pads protect its tiny chicks when they are too small to jump from pad to pad?

You would think that mother birds would be the protectors but in the social structure of African jacanas (Actophilornis africanus) the females can have multiple mates and never settle down, so it’s up to the fathers to build the nest, hatch the eggs and protect their kids.

Watch how this dad protects his young.

Right Now You Can Kayak in Death Valley

26 February 2024

In case you missed it …

During the Ice Age, the Pleistocene 2.58 million to 11,700 years ago, there was a lake 600 feet deep in Death Valley where Badwater Basin stands today. Named Lake Manly(*) by geologists, it disappeared 10,000 years ago.

Badwater Basin is 282 feet below sea level so any water that reaches it can only evaporate yet the evaporation rate is so high that the basin is a salt pan. Occasionally — decades apart — there’s enough rain to make a shallow lake.

In the past six months California has had two unusual rain events. On 20 August 2023 Hurricane Hilary dumped 2.2 inches and caused Lake Manly to re-form in place. (The deluge also closed the Death Valley National Park for two months.) Amazingly the lake persisted through the winter.

And then the Atmospheric River event of 4-7 February dumped 1.5 more inches of rain. Lake Manly grew to a depth of 1 to 2 feet so in mid-February the National Park Service opened it to kayaking.

The last time the lake formed, in 2005, it lasted only about a week. This time NPS estimates it’ll be gone — or at least too shallow for kayaks — by April.

So if you want to kayak in Death Valley, get out there now before Badwater Basin returns to normal.

p.s. From Wikipedia: “The lake was named in honor of William Lewis Manly, who rescued immigrants from Death Valley in 1849.”

Seen This Week: Sky and Water

This week featured spectacular sun effects and high water.

On 11 January I captured this photo of a sun pillar at sunrise while Dave DiCello got an even better shot from the West End Bridge.

Friday’s sunrise was spectacular in a different way.

Tuesday 9 January produced the classic Gleam at Sunset in which a day of thick cloud cover ended with a gap on the western horizon and 30 minutes of sun. Here’s what the gap looked like just after sunset from the roof deck of my building.

Twenty minutes earlier I had viewed the gleam from below when it lit the tops of trees and buildings … like this.

Meanwhile we’re only 13 days into January and have already had 2.24 inches of precipitation — 1.06 inches above normal for the month. All that water ends up in the rivers so it’s no wonder that the Monongahela River was running high at Duck Hollow on 11 January.

Will Pittsburgh Get Cold Enough for Rare Gulls Next Week?

11 January 2024

Only a few days ago I was lamenting that we weren’t having a snowy winter, neither snow nor snowy owls. Well, be careful what you ask for! A few days of bitter cold are coming to Pittsburgh next week. If Lake Erie freezes, arctic gulls will fly south to find open water on the rivers. The photo above shows some cold and happy birders looking at rare gulls at the Point in January 2015.

So what are the chances this will happen next week?

As of this morning, the forecasted low temperature for dawn on Wednesday 17 January is 9°F. This map for next Monday sure looks like we’re in a “polar vortex.” Cold, right?

Low temperature forecast for Monday 15 January 2024 as of 11 Jan ( from the NWS)

But will it be cold long enough to freeze Lake Erie and send the gulls south? Probably not. The eastern Great Lakes ice map as of yesterday, 10 Jan 2024, shows nearly 100% open water (white).

Eastern Great Lakes Ice Chart as of 10 Jan 2024 (map from North American Ice Service)

There’s not even a hint of ice (blue) on most of Lake Erie and the Great Lakes ice-to-date graph for winter 2023-24 indicates that ice is at a near record low. There’s a lot of cooling off to do before the lakes will freeze.

So next week I’ll have to wear my Minnesota gear to go outdoors but it’s unlikely there will be any unusual birds out there. Will I want to go out in 9°F anyway? I’ll have to wait and see.

The Sea of Stars

Yesterday I wrote about seeing stars in the sky. Today we’ll see stars in the sea in this video at Vaadhoo Island, Maldives.

You don’t have to travel as far as the Maldives to see bioluminescent waves but it is not a common phenomena and few places are as reliable as this one.

Wildlife in the Borderlands

14 December 2023

Watering holes are places of abundant wildlife in Arizona’s Sonoran desert as captured on this trail cam in the borderlands. One of the night visitors is a ringtail (Bassariscus astutus), a member of the raccoon family, shown above. (There are two embedded videos below; please wait for them to refresh.)

When water crosses political boundaries animals cross, too, back and forth from Arizona to Mexico. But now the Border Wall makes most of that impossible.

This vintage article explains.

UPDATE on 15 Dec: Here’s the Border Wall.
