Birdsong to Sooth Your Day

video embedded from Lesley the Bird Nerd on YouTube

17 April 2026

Do you need a break from stress and pressure? This 4-minute video will sooth your day.

Listen to the special songs we hear in southwestern Pennsylvania in mid-April as migratory birds sing on their way north. Recorded by Lesley the Bird Nerd in late May or very early June 2025 in Ontario, Canada, the singers have arrived at their destination. (Note: American crow is always here; bluejay is silent in the video.)

I used Merlin to confirm the songs and listed the species’ current status in our area.

  • White-throated sparrow (Zonotrichia albicollis) — about to depart
  • Black-throated green warbler (Setophaga virens) — early birds have just arrived
  • Ruby-crowned kinglet (Corthylio calendula) — they’re here and loud!
  • Yellow-rumped warbler (Setophaga coronata) — early birds have just arrived
  • Red-breasted nuthatch (Sitta canadensis) — all are gone, except for a couple of individuals
  • American crow (Corvus brachyrhynchos) — always here

Note that Merlin does not acknowledge songs that “cannot occur” at the location where it is listening so there may be additional birds that I cannot hear and Merlin is ignoring.

Bonus information:

Why is birdsong so soothing? See 5 reasons why.

For instance, a study in 2022 investigated the effect of urban (traffic noise) vs. natural (birdsongs) soundscapes on mood, anxiety, paranoia.

295 participants were exposed to one out of four conditions for 6 minutes: traffic noise low, traffic noise high, birdsong low, and birdsong high diversity soundscapes. Before and after the exposure, participants performed a [cognitive] task and filled out depression, anxiety, and paranoia questionnaires. The traffic noise soundscapes were associated with a significant increase in depression… Concerning the birdsong conditions, depression exclusively decreased after exposure to the high diversity soundscape. Anxiety and paranoia significantly decreased in both birdsong conditions [low and high].

Nature: Birdsongs alleviate anxiety and paranoia in healthy participants

Who’s Singing Now?

16 April 2026

Who’s singing now? In mid April we hear the usual suspects — American robin, northern cardinal, house finch, song sparrow — but there are new additions to the soundscape.

Ruby-crowned kinglets (Corthylio calendula) are passing through for a couple of weeks on their way to their breeding grounds in Canada.

They’re almost hyper-active as they flit and flutter to glean insects, making “jit” contact calls and pausing to belt out their rolling song. Sometimes they sing when challenging another kinglet, in which case they both raise their ruby crowns (photo at top).

Did you know that ruby-crowns are not closely related to other the kinglets? In 2021 they were moved to a genus of their own.

Chipping sparrows (Spizella passerina) are back in town and singing their dry, rapid trill from prominent perches in the trees.

When you hear the song, look for a sparrow with a rusty cap, eyeline and clear breast. He’s smaller than a song sparrow.

Eastern towhees (Pipilo erythrophthalmus) leave southwestern Pennsylvania for the winter so it’s a sure sign of spring when we hear “che-wink” and “Drink Your Teaeeeeee” coming from the thickets.

The male towhee perches prominently when he sings. The female tends to skulk.

Their songs may have regional accents. The recording by Aidan Place in 2020, below, is typical of the rapid condensed song we hear at Frick Park. It’s different from the one in Ontario above.

Some northern flickers (Colaptes auratus) are here year round but they’re not noticeable until spring when they hammer loudly and call like a “Jungle Bird.”

Loud is Good. Metal is the best.

p.s. The flicker in the video looks different from ours because he’s the red-shafted subspecies found in western North America. (This one is in Vancouver, BC, Canada.) The top of the bird is similar to our yellow-shafted flicker except for face and red moustache. However the underside is red where ours are yellow. Click here to see.

Can You Hear Me?

26 March 2026

Songbird migration kicks off with two small birds that are easiest to find if you can hear them.

The brown creeper (Certhia americana) climbs and zigzags up tree trunks and large branches, probing under the bark for insects. When he reaches the top he flies down to the base of the next tree and climbs up again. He’s hard to see because he flattens himself against the tree and his back matches the bark. However he makes a high pitched contact call that helps pinpoint his location.

Here’s the sound of a brown creeper foraging at Seal Island, Nova Scotia. Do you hear the low horn in the harbor? Can you hear the brown creeper’s call?

Golden-crowned kinglets (Regulus satrapa) are tiny birds that flit and hover as they forage for insects in the trees. Because they move a lot I notice them when I look at the silhouettes of bare branches against the sky. They also make high-pitched contact calls.

Here’s a golden-crowned kinglet calling as it forages in New Hampshire, repeating his single note throughout the recording. Near the end you’ll hear the low “brock” of a raven and then the “ank ank ank” of a red-breasted nuthatch. The kinglet speaks as well, before the raven and after the nuthatch. Can you hear him?

I used to identify these two species by sound but I cannot hear them anymore. Kinglets were the first to go. Seven years ago I wrote about upper-range hearing loss:

If you can’t hear kinglets [and brown creepers] you are probably over age 65, perhaps younger, and probably have age-related hearing loss. Presbycusis affects 1 out of 3 of people by age 65 and half of us by age 75.

See a video of loud golden-crowned kinglets in my 2019 article:

Yesterday in Schenley Park it was very sunny but without a spot of green. However, I found tulip sprouts in a garden (above).

It was so sunny that the rocks on the gravel trail made interesting shadows.

The early birds are already singing. Yesterday I saw and heard northern cardinals and song sparrows in Schenley Park. Here are examples of the songs you will hear this week:

Northern Cardinal:

Look Closely. Ravens!

19 February 2026

Crows are legion in Pittsburgh right now but ravens are increasingly common. They present an identification challenge so you have to look closely at flying black birds. Here in Pittsburgh they are usually crows but you might see two ravens. Yesterday I saw a pair outside my window.

Many people think ravens are just “large crows” but this is not a helpful comparison because the two species are rarely close to each other. Don’t look at size at all! Compare Tails and Voice.

Tails: My diagram below shows the difference. Ravens’ tails are long diamond shapes. Crows are rounded.

Raven and crow tail shapes (diagram by Kate St. John)

Look at the tails. Who’s in the photo at top? Who’s in the photo below?

Voice: Both species announce themselves and they definitely sound different. If you hear “Brock Brock” it’s a raven, “Caw Caw” is an American crow. Bonus in Pittsburgh: “Uh oh” is a Fish Crow.

This audio clip from Xeno Canto has both species: a raven in the foreground (Brock! Brock!) and crows cawing in the background.

Ravens also have an amazing vocal repertoire including these unusual sounds when a pair of mated ravens is together.

Pairs of American crows also make special noises to each other. No, they don’t sound like ravens.

Keep in mind that you do not have to identify every bird you see! If Tails and Voice don’t give you a definitive answer, you can just let the bird be “unknown” or “corvid species.” It’s OK.

Whatcha Sayin’, Raven?

Raven calling … to who? (photo by JMaughn via Flickr Creative Commons license)

23 December 2025

Common ravens (Corvus corax) are well studied, highly intelligent birds who often have a lot to say, but we don’t know what it means. Not only do they make a wide array of sounds but they may use them in almost any context.

In the last 50 years of studying raven voices researchers found …

In a contextual analysis of raven communication, calls were shown to indicate more about what was not going to happen next than they did about what was going to happen next.  Vocalizations also tended to inhibit behaviors of receivers rather than elicit behaviors.

Birds of the World, Common raven vocalizations

Here are several examples of raven vocalizations. Whatcha sayin’, Raven?

Common raven vocalizing at Marbury (Whitchurch) near the Llangollen canal by @MarburyBirds on X:

This call draws my attention to a raven overhead in Pittsburgh. “Brock, Brock”

Knocking?

Shouting!

There’s a raven in the center birch tree who has a lot to say about, or perhaps to, the dog.

And finally if you have the time, listen to this group of ravens having a 9-minute conversation in the Michigan woods.

Strange Crow Sounds

18 November 2025

If you think you can’t recognize birds by song I guarantee there is one whose voice you know. “Caw! Caw! Caw! Caw!” the American crow (Corvus brachyrhynchos).

Crows are especially vocal when they see a predator. If you hear this, look for the owl!

And there’s the Double Short Caw that I often hear in summer. (I have not found a recording of it.)

Caw-Caw.   Caw-Caw.   Caw-Caw.

Double Short Caw. A series of caws delivered in pairs, so that the interval within a pair is smaller than between pairs. Often associated with territorial bouts, Countercawing, directed out of the territory, and particularly with the beginning of chasing bouts. Function as call-to-arms vocalizations for family members.

Birds of the World: American crow vocalizations

Beyond cawing, crows make many strange sounds including rattles, growls, coos and clicks, as seen in this video from @Crows_are_skycats in Seattle.

The Rattle Call is really special. In 2008, R.R. Tarter, found evidence that this sound is only made by the female. Tarter, R. R. (2008). The Vocal Behavior of the American Crow, Corvus brachyrhynchos [master’s thesis]. The Ohio State University

Danger! Hawk!

10 July 2025

Birdsong is coming to an end as the breeding season wraps up but birds are still making contact and warning calls. In a recent walk in Frick Park Charity Kheshgi pointed out a robin saying “Danger from the air!” a sound so high-pitched that I no longer hear it.

Upper frequency sounds are hard to pinpoint so a robin saying “Danger! Hawk!” should be hard for the hawk to find … except that robins making this warning call usually stand out in the open, as the shown above.

Learn to identify robin and starling warning calls in this vintage article. Unlike birdsong these sounds happen all year long.

The Nunbird Chorus

27 December 2024

White-fronted nunbirds (Monasa morphoeus) are at their most interesting when they sing in “group choruses of loud gobbling, barking notes, sustained for up to 20 minutes at a time, chiefly at the beginning and end of day.” — quoted from Birds of the World.

If you wanted to hear them in the wild, go to these regions of Central and South America.

p.s. “White-fronted” describes birds whose foreheads are white such as the greater white-fronted goose and white-fronted nunbirds.
