14 Years Of Blogging

14 years of blogging (party crow by Joan Guerin)

9 November 2021

On this day in 2007 I posted my first blog at Outside My Window. Today in celebration let’s look back at three memorable articles from my first month of blogging.

Clash of the Titans: On the advent of a new raptor pecking order a male Pitt peregrine chases Central Catholic’s red-tailed hawks.

Thank you, my readers, for keeping me going every day. And a very special thank you to the many photographers who allow me to use their photos and videos on the site.

Happy 14th Bird-thday to the Blog!

Fall Back an Hour Closer to Zulu Time

6 November 2021

When Daylight Saving Time ends tonight our time zone will move one hour closer to Zulu Time.

Zulu (Z) Time is the aviation and military name for Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC). Wikipedia explains that back in 1950, when time zones were identified by successive letters of the alphabet, the Greenwich time zone was marked by a Z as the point of origin.  Z in the military alphabet is called “Zulu.” Z time = GMT = UTC.

Pilots use Zulu Time for navigation described in the video below. The internet and your cellphone use Z time behind the scenes.

Time Zones around the world are a patchwork based on local laws. Most of the world does not participate in DST though more than half of the world used to. This morning’s screenshot from (6 November 2021, 4:45 EDT) will look different in North America tomorrow morning. Click here to see how the colors changed in North America on 11 Nov 2021.

Time zone map screenshot from at 6 Nov 2021, 4:45am EDT

I’m not a fan of changing the clocks and wouldn’t mind if we changed them tonight and never changed again. 🙂

Further reading:

  • Click here for the NATO phonetic alphabet where A,B,C… is Alpha, Bravo, Charlie…
  • Example of internet Z time: When I download my cellphone photos from Google to my computer they are labeled in Z time, not in the local time they were taken by my cellphone.
  • Most of the world does not participate in DST. Light gray areas on the map stopped participating, dark gray never used DST.

When: Sunday 31 October 2021, 8:30a-10:30a.

Where: Meet at the Duck Hollow parking lot at the end of Old Browns Hill Road.

Dress for the weather and wear comfortable walking shoes. Bring binoculars, field guides and a birding scope — if you have them.

Visit the Events page before you come in case of changes or cancellations.

This outing is on Halloween. Will the ducks be in costume? Will they be wearing hats?

Blue Jays and a Monkey Ball: Today in Schenley Park

Participants in this morning’s outing in Schenley Park, 26 Sep 2021 (photo by Kate St. John)

26 Sep 2021

This morning was sunny and chilly with heavy dew when fifteen of us gathered for a walk in Schenley Park. All of us are in this photo though I am just a long shadow of my usual self.

Last night’s weather sucked most of the migrating birds out of Schenley Park and did not add any new ones. I expected to see 20 species; we saw only 10. I expected 100 individual birds; we saw 63. Of those 55% were blue jays.

Plants, however, filled the gap especially this broken osage orange (Maclura pomifera) or “monkey ball.”

Its insides are damp with latex, its seeds enveloped in plant flesh. Few animals eat this fruit so why does the tree produce so much? It’s making fruit for giants. Learn more and see a video at Food For The Extinct.

20 September 2021

Though it hasn’t felt like it lately, fall will arrive on the equinox this Wednesday at 3:21pm ET. With it will come cooler temperatures, morning dew and migrating thrushes. It’s a good time to be outdoors.

Join me for a bird & nature walk in Schenley Park on Sunday, 26 September 2021, 8:30a – 10:30a(*). We’ll meet at Bartlett Shelter on Bartlett Street. Note that Forbes and Fifth Avenues will be closed for the Pittsburgh Great Race so plan your route accordingly. See road closures times below.

We’re sure to see blue jays, chipmunks, autumn flowers and fruits. I hope for at least one Swainson’s thrush, rose-breasted grosbeak or ruby-crowned kinglet, passing through the park on their way south.

Dress for the weather and wear comfortable walking shoes. Bring binoculars and field guides if you have them. NOTE that storm damage from Hurricane Ida is still present in the park though not as prevalent at the Bartlett end. Be prepared for some rough spots. A walking stick may be useful.

Visit my Events page before you come in case of changes or cancellations.

(*) If the birding is suddenly good at 10:30am we’ll have the option to continue to 11a.

Birds and Women at Work

6 September 2021

On Labor Day, let’s take a look at birds of prey working with women.

Falconry in Europe evolved from a sport of the nobility to a career accessible to the middle classes. Though considered a man’s sport, aristocratic women in medieval and early-modern Europe took part in large numbers and became renowned for their falconry skills, often better than men. When falconry declined in the 18th century far fewer women were involved, making this 1880 portrait of Die Falknerin (The Falconer) and the following 1881 illustration of the same woman in Die Gartenlaube unusual in its rarity. Who is this falconer holding a Eurasian kestrel in a land that speaks German?

Die Falknerin, portrait by Hans Makart, 1880

Nowadays women falconers work at raptor centers, aviaries and bird abatement services that use falcons and hawks to move nuisance birds.

At top, a woman falconer works with a gyrfalcon at the Salzburg Regional Falconry Centre at Hohenwerfen Castle, Austria where they hold daily flight demonstrations with various birds of prey. The falconers live at the castle so they can better take care of the birds.

Below, Sabrina Fox flies a Harris hawk in Portland, Oregon in 2018 to move the winter crow flock out of the city center.

In Idaho, women at the World Birds of Prey Center in Boise fly a peregrine falcon and a harpy eagle in a flight show.

And in Pittsburgh, women falconers work with birds at the National Aviary. In 2011 Cathy Schlott displayed a lanner falcon at an event at WQED.

Today in Schenley Park, Aug 29

Schenley Park outing, 29 August 2021 (photos by Kate St. John)

29 August 2021

This morning’s outing in Schenley Park was very well attended — 28 people! — so I had to paste two photos together to get (almost) everyone in.

The weather was clammy-hot and the birds were not active but bugs were easy to find. Can you see the green stink bug (Chinavia hilaris) in this picture?

We also saw cocklebur as promised and an unusual invasive, yellow nutsedge (Cyperus esculentus), which is cultivated in Eurasia for its edible tubers eaten as snack food or made into a sweet milk-like beverage.

Our Best Bird was a lucky find. As we stood next to Panther Hollow Lake a peregrine falcon zoomed overhead, went into a stoop, and disappeared beyond Phipps Conservatory on his way to the Cathedral of Learning.

We worked for every bird on this checklist at

Schenley Park–Panther Hollow, Allegheny, Pennsylvania, US

Schenley Park Outing: August 29, 8:30am

Common cocklebur, Schenley Park, 20 Aug 2021 (photo by Kate St. John)

23 August 2021

In late August summer flowers are blooming, bugs are singing, and warblers are on the move.

Join me for a bird & nature walk in Schenley Park on Sunday, August 29, 2021, 8:30a – 10:30a. (If the birding is great we may linger until 11a.)

Meet at the Schenley Park Cafe and Visitor Center where Panther Hollow Road joins Schenley Drive (40.4383304,-79.9464765).  I hope to see migrating songbirds and at least one confusing fall warbler.

I know we’ll see this native weed, common cocklebur (Xanthium strumarium), growing in a disturbed area next to Panther Hollow Lake. Notice the big leaves and spotted stem. Did you know it has separate male & female flowers on the same plant? This location used to be overrun with mugwort but since it was torn up last spring it now has cocklebur. At least it’s native.

Dress for the weather and wear comfortable walking shoes. Bring binoculars and field guides if you have them.

Before you come, visit my Events page in case of changes or cancellations. The outing will be canceled if there’s lightning.

Hope to see you there!

Today’s Outing at Frick Park, July 25

Outing in Frick Park, 25 July 2021 (photp by Kate St. John)

25 July 2021

Nine of us gathered this morning at the Nine Mile Trail parking lot to walk Frick Park’s Boardwalk and the upper Nine Mile Run valley. At the beginning it was very cloudy but it didn’t rain.

The birds were quiet. Many have stopped singing for the year and gray skies made the rest of them subdued. Nonetheless we saw northern rough-winged swallows feeding young in flight and heard the warning calls of wood thrushes, robins and tufted titmice in a spot where a barred owl often roosts. Alas, we never found the owl.

It’s hard to pick a Best Bird but easy to pick the worst smell. We had to walk (as far away as possible!) past a decomposing deer near Commercial Street. Where are the turkey vultures when you need them? We didn’t see any today. Our list has 24 species.

Chimney Swift (Chaetura pelagica)  1
Red-bellied Woodpecker (Melanerpes carolinus)  2
Downy Woodpecker (Dryobates pubescens)  4
Northern Flicker (Colaptes auratus)  3
Eastern Wood-Pewee (Contopus virens)  1
Acadian Flycatcher (Empidonax virescens)  1
Warbling Vireo (Vireo gilvus)  1    Heard
Red-eyed Vireo (Vireo olivaceus)  7    Pair chasing and harassing a blue jay
Blue Jay (Cyanocitta cristata)  1
Carolina Chickadee (Poecile carolinensis)  2
Tufted Titmouse (Baeolophus bicolor)  10
Northern Rough-winged Swallow (Stelgidopteryx serripennis)  10
Carolina Wren (Thryothorus ludovicianus)  7
European Starling (Sturnus vulgaris)  5
Gray Catbird (Dumetella carolinensis)  1
