Last weekend in Hamilton, Ontario we wanted to see Albion Falls cascade over the Niagara Escarpment but it was foggy.

However at ground level there were beautiful water droplets on all the plants. Many of them “weeds” but all looked gorgeous. Top to bottom:

  • Perennial sow thistle
  • White sweet clover
  • Common salsify
  • Gray dogwood berry stems shrouded in cobwebs
  • Tartarian honeysuckle berries

Back in Pittsburgh I see deer every day now in my neighborhood. These two are munching a garden on Neville Avenue — a 6-point buck in velvet with a doe. They are a persistent couple.

I Still Don’t Wanna Grow Up!

10 July 2026

On Tuesday morning, 7 July, I was chatting with friends at Schenley Plaza when I heard a young peregrine whining for food — a normal sound in early June when young peregrines have just fledged but atypical in July.

I looked up to see the whiner chasing her parents around the Cathedral of Learning. Yes, it was Yellow. She arrived at the nest the previous evening when her parents were not around.

Right now the Pitt peregrines are mostly off camera but there are occasional moments of excitement. Ecco and Carla bow at the nest. Yellow pops in unexpectedly.

Check the snapshots to see if someone’s on camera. Tune in to the National Aviary falconcam to find out who it is. The falconcam will stay up through the end of July. Show your support at the National Aviary’s Adopt-A-Bird program.

Meanwhile Yellow still doesn’t want to grow up. How long can this go on? Sooner or later she has to leave home.

Insects in Camouflage

Now that Bug Season is in full swing it’s fun to find the bugs in camouflage.

Planthoppers are parasites that suck the juice from plants, though they rarely reach the pest level in their native range. They barely move when perched but if you jostle them they jump like grasshoppers. Plant.Hoppers. Every life stage uses camouflage to hide from predators.

Google Lens identified the bug at top as an Acanalonia planthopper that sucks the juice of woody plants. Usually green in color, the adult is trying to look like a leaf.

Some species of flatid planthoppers are white so how are they camouflaged?

The adult females secrete a white waxy substance to protect their eggs and young. The adults resemble moths as they hang out in a white fuzz zone.

Planthoppers are parasites who are parasitized by a moth.

This well-camouflaged planthopper parasite caterpillar (Epipyrops exigua) feeds on the body fluids (haemolymph) ofย planthoppersย andย cicadas.

After he transforms into an adult, he is still camouflaged.

I’ve never seen the caterpillar and moth but I’ll look more closely now when I find planthoppers.

City Fawn Learns From Mom

8 July 2026

Yesterday on Ellsworth Avenue my husband was surprised to see a curious fawn inside the Hunt Mansion fence. The fawn began to approach him. Where was its mother?

Not far away. After a few steps the fawn paused and went to mom nearby. Its mother taught it that humans on the sidewalk are not dangerous, but don’t get too close.

The doe must have indicated she was going outside the fence. “I’m going to eat that hedge. Go to your hiding place while I’m gone.”

The doe crossed the street to the yard with the delicious hedge and the fawn trotted away.

So this doe I saw last week has a fawn.

Two Kinds of Ticks, All Kinds of Trouble

Two bad ticks in PA: black-legged tick and lone star tick (photos from Wikimedia)

7 July 2026

At last the heat has broken and we’re able to enjoy the outdoors again, but don’t get too cocky. Tick bites are way up this year and they are TROUBLE.

For most of the country, weekly emergency visits for tick bites are at the highest rates for this time of year since 2017, according to the CDC.

This means that even on vacation you’ve gotta watch out for ticks.

The bites of two species can make you very sick: black-legged ticks and lone star ticks. This diagram shows their relative size and shape, shown with the familiar dog tick for comparison.

Comparing three species: black-legged, lone star and dog ticks (diagram from CDC via Wikimedia)
Blacklegged tick (Ixodes scapularis)

Black-legged (or “deer”) ticks are at the top of the danger list. They are exceptionally plentiful and they spread Lyme disease.

Don’t let this tick get on you!

Just about anywhere you’d want to vacation in the Northeast and Great Lakes States is prime territory for black-legged ticks. Planning a beach vacation? Notice that this tick is there too.

Range map of blacklegged tick (from CDC)

Pennsylvania has the highest number of Lyme disease cases in the U.S.

Reported cases of Lyme disease in US, 2023 (map from cdc.gov)
Lone star tick (Amblyomma americanum)

The Lone Star name has nothing to do with Texas. In this case the lone star tick is named for the white dot on the female’s back.

These ticks are especially plentiful in the Southeast and have begun moving into PA. When they bite they transmit a protein in their saliva that causes an allergic reaction to mammalian foods — meat and dairy products — called alpha gal syndrome.

There are a plague of these ticks on Martha’s Vineyard. So many people have alpha gal syndrome that restaurants and farmer’s markets have changed their product offerings.

What can you do to protect yourself?
It’s Spray Your Clothes Day (photo by Kate St. John)

#1. Don’t let ticks get on you. Word to the Wise: Spray your clothes before you go out.

#2. Field check for ticks. Brush them off before they bite!

#2. If a tick is biting you, use tweezers to remove it. Do not wait to remove a tick. The longer it’s on you the more disease it can give you.

Sand Cats Found in Libya

6 July 2026

There is an elusive desert wild cat that is so similar in size and shape to a domestic cat that it could be mistaken for one. The sand cat (Felis margarita) lives in disjoint areas in deserts from North Africa to the Middle East to Turkmenistan and is so well camouflaged that it is almost impossible to see in the wild. They are always in remote desert areas and possibly extinct in some of their range.

Sand cats were not found in Libya, until Mohammed Almuntasir posted this video on YouTube in 2017.

Almuntasir often received inquiries about the video but it led nowhere until Firas Hayder at Sol Plaatje University in South Africa proposed searching for and mapping sand cat locations using GPS, still shots and video.

It was a dangerous effort for humans because of armed smugglers in the region. However, the 8-year collaboration placed the sand cat on the map in Libya. I’ve hand drawn the approximate location in blue.

If you’ve seen a sand cat in a zoo I’m sure you’ve been surprised by how much it looks like the cats at home(*). These are the zoo-bred descendants of sand cats caught in southwestern Pakistan in the early 1970s and exported to zoos worldwide. Sand cats are gone from Pakistan in the current map. It is encouraging to hear they are in Libya.

Seen This Week: Deer, Heat and Hamilton

5 July 2026

In my neighborhood on 1 July I encountered a deer very close to the sidewalk who didn’t care that I stared at her.

She was eating a large Japanese spindle hedge (Euonymus japonicus)*, a plant that is toxic to humans and pets but not toxic to deer. She must be eating it day after day because the long hedge is damaged and see-through.

Terribly hot weather. Even the sunset looked hot.

So we’re on a mini-vacation in Hamilton, Ontario where it is not as hot. “Why Hamilton?” asked the Canadian immigration officer at the Peace Bridge. Well, we didn’t want to drive all the way to Toronto. Fair enough.

Hamilton (H on the map below) is on the way to Toronto (T) and more than an hour+ from the Peace Bridge in Buffalo (B). As we learned, there is a lot of stop and go traffic on the expressway.

Annotated Great Lakes satellite map from Wikimedia Commons

Hamilton is at the westward tip of Lake Ontario and is bisected by the Niagara Escarpment, a 650-mile cliff that arcs from New York state to Ontario, Michigan and Wisconsin. It is not a fault line but the result of unequal erosion with hard rock on the cliff top and eroding limestone on the cliff face. Both the Genesee River in Rochester, NY and Niagara Falls cascade over the Niagara Escarpment.

Both the lake and the escarpment are visible from our hotel windows.

But not visible today. We were going to see the escarpment but it’s foggy.

(*) p.s. It’s possible that I’ve misidentified the hedge the deer was eating. Cultivated Euonymus japonicus and E.Fortunei are very similar.

On Independence Day 250

4 July 2026

Today we celebrate the signing of the Declaration of Independence in Philadelphia in 1776, 250 years ago.

We often hear a sentence or two from the Declaration but it’s worth a look today to see how well it holds up. I have transcribed the beginning below. NOTE: I added 1 paragraph break for readability.

Beginning of the United States Declaration of Independence (first 288 words)

In CONGRESS, July 4, 1776.

The unanimous Declaration of the thirteen united States of America,

When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.โ€”That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,โ€”That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

Following this, the signers provided a list of grievances (29 paragraphs) documenting King George III’s “repeated injuries and usurpations” of the Americans’ rights and liberties. What were they? Here are nine of them, paragraphs 12 through 20 quoted below.

United States Declaration of Independence list of grievances, paragraphs 12 through 20.

He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.

He has affected to render the Military independent of and superior to the Civil power.

He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation:

For Quartering large bodies of armed troops among us:

For protecting them, by a mock Trial, from punishment for any Murders which they should commit on the Inhabitants of these States:

For cutting off our Trade with all parts of the world:

For imposing Taxes on us without our Consent:

For depriving us in many cases, of the benefits of Trial by Jury:

For transporting us beyond Seas to be tried for pretended offences:

I usually write about Birds & Nature. A natural event is in the photo at the top. On 10 June 2021 an annular solar eclipse was visible from parts of Russia, Greenland, and northern Canada. Those in Northern Asia, Europe, and the United States saw aย partial eclipse. This is what it looked like near the Statue of Liberty. Photo by Anthony Quintano posted on Wikimedia Commons.

Red is On His Way to Rehab

3 July 2026

In early June I routinely saw only one juvenile peregrine at the Cathedral of Learning. This was puzzling because young peregrines usually hang out at home for a couple of weeks, chasing their parents and playing in the sky with their siblings. Where were the other three? Puzzle solved for one of them: “Red” was rescued in early June and is on his way to rehab.

On Tuesday morning 9 June, the young male peregrine “Red” (Black/Green 09/Z) was found bleeding and stunned at 4400 Forbes Avenue near Carnegie Museum. He was admitted to Humane Animal Rescue of Pittsburgh’s Wildlife Center (HARP) in Verona at 7:00am where the team treated his wounds and evaluated his condition.

Red must have hit something really hard head first because his head was bleeding and he had a concussion. Katie Kefalos, Director of Wildlife Rehabilitation, also told me his lead tests came back positive. He was treated for lead and his levels returned to normal.

HARP was hopeful that Red could rejoin his family soon for hunting school but on 18 June, wounds healed and lead-free, he flunked his flight test. He was too wobbly to go home. (Concussions can do that.)

Yesterday, 2 July, Red had another flight test but his skills were still not where they should be for him to learn to hunt. Meanwhile his parents, Carla and Ecco, have moved on from hunting school to “it’s time to leave home, kids.”

At this point Red needs to gain strength and balance and learn to hunt so he can become an independent peregrine. HARP has arranged for Red to be transported to Tamarack Wildlife Center whose rehab facility is equipped to help Red through the next steps.

Red has been a celebrity at HARP and is featured on their fundraiser page. If you’d like to thank HARP for helping Red and injured wildlife, consider a donation by clicking here or on the photo below.

You might also consider giving a boost to Tamarack Wildlife Center for their upcoming work with Red.

Red doesn’t know it, but he thanks you.
