Better Birds Desired

6 October 2021

In early October it’s easy to find pigeons, red-bellied woodpeckers, northern flickers, blue jays and chickadees in Pittsburgh. Ho hum! I wish for better birds.

At Jackson Lake in Los Angeles County, California last Sunday, there were similar but more interesting species. Here’s a sampling from Ted Keyel’s eBird checklist.

Instead of rock pigeons there were band-tailed pigeons (Patagioenas fasciata), North America’s largest wild pigeon.

Instead of red-bellied woodpeckers (Melanerpes carolinus) there were two other Melanerpes. A flock of 40-60 migrating Lewis’s woodpeckers (Melanerpes lewis) …

… and six acorn woodpeckers (Melanerpes formicivorus).

We have northern flickers in Pittsburgh but they are yellow-shafted (click here to see). In California northern flickers (Colaptes auratus) are red-shafted. Wow!

Instead of blue jays California has Steller’s jays (Cyanocitta stelleri).

And instead of black-capped or Carolina chickadees they have mountain chickadees (Poecile gambeli).

These are much better birds!

How Fast Do Songbirds Migrate?

27 September 2021

During fall migration warblers pass through Pittsburgh, followed by thrushes, then sparrows. We see them during the day after they’ve flown all night. Where were they yesterday? How far will they fly tonight? How fast are they traveling? What is their destination?

The answers are weather dependent, of course, but they also vary by species. Here are three recent songbird examples.

Wood thrush (Hylocichla mustelina)

Wood thrushes (Hylocichla mustelina) breed across the eastern U.S. and southeastern Canada, then spend the winter in Central America.

In 2009 a geolocator study of wood thrushes by Bridget Stutchbury found that:

  • Wood thrushes fly more than 311 miles a day on migration. If they fly 8-10 hours per night their air speed is 30-38 miles per hour.
  • They dawdle in the fall by stopping over in the southern U.S. or the Yucatan for one to four weeks before proceeding to their final destination.
  • Wood thrushes return two to six times faster in spring because they barely stop at all.
  • They shorten the trip by flying across the Gulf of Mexico overnight, a distance of 600 miles from the Yucatan to Louisiana.

Where was that wood thrush yesterday? Maybe north of Toronto, Ontario. When he leaves how far will he fly? Perhaps to Lexington, Kentucky.

Blackpoll warbler (Setophaga striata)

Blackpoll warblers (Setophaga striata) spend a lot of time fattening up before they leave North America for their wintering grounds in Brazil because they fly non-stop over the Atlantic Ocean to get there.

Their route averages 1,900 mi (3,000 km) over open water, requiring a potentially nonstop flight of around 72 to 88 hours. They travel at a speed of about 27 mph (43 km/h).

Some blackpolls take off from Cape Cod. Some launch from coastal Virginia. Where was that blackpoll yesterday? If you’re asking this in Pittsburgh he might not have been very far north. Where will he be tomorrow? If you’re asking this on the U.S. coast the answer is “over the Atlantic Ocean.”

American robin (Turdus migratorius)

American robins (Turdus migratorius) take their time in the fall. Since they can live year round in much of the U.S. those that leave their breeding grounds (yellow on map) can afford to linger on their way south. Robins leave when the ground freezes or is covered by snow. Some travel as far as Florida, Mexico and Central America but most do not.

American robin range (map from Wikimedia Commons)

When on the move American robins have been clocked at 20-36 mph. They are faster when migrating than when they fly in our backyards.

So where was that robin yesterday? Probably here in Pittsburgh. Where will he be tomorrow? If he decides to fly all night he can reach Lexington, Kentucky with the wood thrush.

Red-Winged Black Bird in South Africa?

16 April 2021

There’s a black bird with red wings in South Africa that resembles North America’s red-winged blackbird except for his outrageously long tail.

The long-tailed widowbird (Euplectes progne) is not related to red-winged blackbirds (Agelaius phoeniceus). The widowbird is a weaver (Ploceidae), red-wings are New World blackbirds (Icteridae), yet male and female widowbirds have very similar coloring to male and female red-wings. The similarity ends when you see his tail.

His tail is an important part of his courtship flight display.

In the video he briefly lands near a female on the ground.

Female long-tailed widowbirds don’t have long tails but they must exert a lot of selective pressure for the longest tailed males.

That tail doesn’t look like a safe accessory. I’m sure some females are widowed during the breeding season. 😉

Easter Island has Christmas Birds

4 April 2021, Easter Day

When Europeans explored the Pacific they sometimes named islands for the day they found them. Thus Easter Island (Rapa Nui) was named by Dutch explorer Jacob Roggeveen who encountered it on Easter Day 5 April 1722 and Christmas Island (Kiritimati) was given its English name by Captain James Cook on Christmas Eve 1777.

Easter Island is best known for its nearly 1,000 stone statues, moai, created by the Rapa Nui people. Kiritimati (pronounced “Ki-rismas” in the local language) is so remote that it was used for nuclear bomb tests 60+ years ago. Today the entire coral atoll is a wildlife sanctuary.

Christmas shearwaters (Puffinus nativitatis) are pelagic birds that nest on remote Pacific islands (map) and were named for their largest breeding colony at Kiritimati, Christmas Island.

They also nest on Easter Island … so Easter Island has Christmas birds.

p.s. Happy Easter 2021.

Uncommon Starlings

3 March 2021

Why is this starling all black?

The European starlings (Sturnus vulgaris) we love to hate in North America are just one of 123 species in the Starling family (Sturnidae). In Europe their English name is “common starling.” Here are seven of their uncommon looking relatives.

Spotless starling (Sturnis unicolor): The common starling’s nearest relative is a non-migratory resident of Spain, Portugal, northwest Africa, and nearby areas. Shown above, he is indeed spotless.

Rosy starling (Pastor roseus): Looks uncommon to us but is common in India in winter.

Violet-backed starling (Cinnyricinclus leucogaster): Native to sub-Saharan Africa, the male is beautiful amethyst, the female is boring brown.

Superb starling (Lamprotornis superbus): Lives in Africa. Definitely superb. Imagine seeing more than one!

Greater blue-eared starling (Lamprotornis chalybaeus): A very common bird of open woodlands in the Sahel and the eastern half of Africa.

Hildebrandt’s starling (Lamprotornis hildebrandti): Lives in Kenya and Tanzania. Oh my!

Mysterious starling (Aplonis mavornata): There is no photo of the mysterious starling because cameras had not been invented when he was found in Polynesia in 1825. Ornithologists went looking for him in 1975 but he was already extinct. Due to the mystery of his origin, there are probably two extinct species of mysterious starlings. Read more here.

Our European starlings certainly look common compared to these.

Seeds Travel By Sea

5 February 2021

Many plants that grow near water disperse their seeds by riding the water wherever it goes. Fabulous among this group are tropical plants whose drift seeds cross the ocean.

The monkey-ladder vine or sea bean (Entada gigas), above, produces hard-covered heart-shaped seeds that contain an air pocket to keep them buoyant. Seeds from the Caribbean and Central America wash into the ocean and float on the Gulf Stream. Some make landfall 15 months later on the shores of Scotland.

This selection of drift seeds was found at the Outer Hebrides.

They can also be found at Orkney as seen in this video from BBC Winterwatch.

The drift seeds traveled more than 4,000 miles to reach Orkney’s beaches and so did a lot of other things.

Benefits of A Rare Bird

12 January 2021

White-crowned sparrows (Zonotrichia leucophrys) are not rare in North America but are extremely rare in Britain. In 2008 a white-crowned sparrow showed up in the small town of Cley next the Sea, Norfolk and stayed for many weeks thanks to Richard and Sue Bending who put seed for it in the drive to their Dawn Cottage home, shown below.

In the UK there’s a lovely tradition of birders (called twitchers) making a donation to a local charity when they come visit a rare bird. In 2008 the parish church St. Margaret’s at Cley next the Sea, built in 1320-1340, was in need of restoration funds so the donations were given to the church. The bird stayed for weeks, ultimately raising 6,000 pounds, more than $11,000 in 2008 dollars. At the time it was the most ever raised by a rare bird.

St. Margaret’s honored the bird with a stained glass window.

And British twitchers honored the bird with a nickname — “badger bunting” — for the badger-like stripes on its head.

Beyond the thrill of seeing a rare bird there can be tangible benefits.

p.s. A tip of the hat to @RyanFMandelbaum for his tweet that tells the story.

p.p.s. I saw the church from a distance in late June 2017 when I visited Cley & Salthouse Marshes on a birding tour with Oriole Birding. I had 12 Life Birds there; Best Bird was Eurasian spoonbill. It’s a great place for birds!

Red-tailed Hawks Look Different In the West

4 January 2021

One of the surprises when traveling in North America is that our most common hawk in Pittsburgh, the red-tailed hawk (Buteo jamaicensis), looks very different out west.

In western Pennsylvania, red-tailed hawks are best identified by the belly band of stripes below their breasts and dark patagial marks on their underwings. Some have dark markings, some are pale. Adults are redder than immatures.

Though most western red-tailed hawks are similar to their eastern cousins they are generally darker, as shown below in Washington state. There’s also a dark morph that’s completely chocolate brown as in the photo at top from San Mateo County, California.

Here are more examples.

Arizona: Underwings on this adult are darker and redder than back east.

Utah: Dark underneath on an immature red-tail.

California: While many red-tails in California are merely darker, the dark morph is over the top.

Some day when we can travel again I’m looking forward to seeing a dark morph red-tailed hawk.

African Hawk With a Red Tail

This is not a red-tailed hawk (Buteo jamaicensis) but it sure resembles one. The augur buzzard (Buteo augur) of Africa also has a lifestyle that resembles North America’s red-tailed hawk.

Take a 6-minute trip to Kenya and learn more about augur buzzards in this video from the Kenya Bird of Prey Trust. You’ll see some parallels with our most familiar hawk.

Quiz: Where Is The Largest Desert on Earth?

Quiz! Where is the largest desert on Earth? What continent is it on?

By “largest” I mean square miles. By “desert” I mean …

A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation. About one-third of the land surface of the world is arid or semi-arid.

Wikipedia entry for Desert

Did you know that the majority of deserts are not composed of sand dunes?

To get you in the mood, here are photos of deserts around the world.

Leave a comment with your answer. I’ll post the answer later today (see below).

Click here for a map (By the way, this map includes the answer but it doesn’t look that way!)

ANSWER: Antarctica! In fact both poles are deserts. The Antarctica Polar Desert is 5.5. million square miles, the Arctic Polar Desert is 5.4 million sq mi and the Sahara is 3.5 million sq mi. Read more about the largest deserts at geology.com.

Why is it a desert? Because the air is so dry. As the Dan Satterfield explains in Scientific Facts That Are Not True:

It cannot be too cold to snow some. It can be too cold to snow a lot. As air gets colder, it can hold less moisture. This is why the Antarctic is the greatest desert on Earth. It’s drier in many places than the Sahara! Climate change is expected to cause more snow in polar regions, not less. Now you know why. (warmer air means it can snow more)
