Tanagers Galore in Ecuador!

3 February 2023, WINGS in Ecuador: Day 6, birding in Mindo and the NW Andes

I used to think hummingbirds (Trochilidae) were the most numerous bird family on our WINGS trip in Ecuador until I looked at the tanagers.

Tanagers (Thraupidae) are the second largest family of birds(*) and a Neotropical specialty. Nearly 40% of Thraupidae species live in Ecuador; 20% of the family is on our tour checklist.

Thraupidae membership is constantly in flux as DNA tests move birds in and out of the family every year. Some species names no longer match their family(**). There’s a tanager called a “cardinal” and members of the Cardinal family Cardinalidae called “tanagers.” To make matters worse some members of the family aren’t called “tanagers” at all, including honeycreepers, conebills, flowerpiercers and saltators.

To bring some order out of the chaos I looked at colorful Thraupidae on our tour checklist whose names include “tanager” and picked 17 of the best for the slideshow. Here they are in order with links to their eBird descriptions and [photo] on Wikimedia Commons.

Loads of Hummingbirds!

30 Jan 2023, WINGS in Ecuador: Day 2, Yanacocha Reserve on Pichincha Volcano

If you want to see hummingbirds, Ecuador is the place to be. It holds the worlds record for the highest number of species and contains about 40% of the total.

The checklist for our tour has 51 hummingbirds on it, 28 of which have been seen every time WINGS makes the trip. The slideshow displays 20 that we’re certain to see. I tried to memorize them in advance but there are just too many!

As you look at the hummingbirds, here’s something to watch for: Nearly every species has a white dot, called a post-ocular spot, or a white stripe of feathers behind the eye. Why do they have this and what is it for? My Google searches cannot find an answer.

Here are the species in slideshow order with links to their eBird descriptions and [photo on Wikimedia Commons].

Hello From Puembo

29 Jan 2023, WINGS in Ecuador: Day 1, Puembo Birding Garden

Today I’m spending my first day in Ecuador at the Puembo Birding Garden, a bed and breakfast with cool birds conveniently located near Quito’s airport. Our WINGS tour opens here tonight at dinner.

Puembo Birding Garden is an eBird hotspot so I found out what I’m likely to see long before I arrived. #1 will be a Life Bird that ranges from Columbia to Ecuador, the scrub tanager (Stilpnia vitriolina), easily attracted to fruit trays even in the rain.

Perhaps I’ll hear a croaking ground dove (Columbina cruziana) that looks like an orange-billed mourning dove and sounds like a frog …

… or the bright red crimson-mantled woodpecker (Colaptes rivolii) …

… or an amazing hummingbird, the black-tailed trainbearer (Lesbia victoriae).

Is It Spring Yet? Asks the Starling

12 January 2023

I know it’s only 12 January but a starling told me on Tuesday that spring is coming soon. I could see it in his beak.

Most of the birds that spend the winter in Pittsburgh wear the same colors all year long. Blue jays, chickadees and red-tailed hawks don’t change their look from winter to spring. European starlings (Sturnus vulgaris) do make a change but it’s subtle.

In winter they live up to their name with “starry” spotted feathers, dull dark pink legs, and gray-black beaks. When spring comes their spots wear off, their legs become brighter red and their beaks turn yellow.

Last Tuesday I saw a starling whose beak was turning yellow, though still black-tipped like the one pictured below.

His ultimate goal is this glossy crisp appearance.

Starling beaks usually start changing in February. Is spring coming sooner than usual or is that starling ahead of the game?

White-throated Sparrows Have Four Sexes

8 January 2023

White-throated sparrows (Zonotrichia albicollis) come in two color morphs with either white-striped or tan-striped heads. The color tells us nothing about the sex of the bird because both morphs contain males and females. Last week a new article about a 2016 study reiterated the white-throated sparrow’s affinity for mating with the opposite color morph. It’s deeper than just a preference. These birds cannot reproduce with their own color.

Thirty years of research by Elaina Tuttle and Rusty Gonser into the genetics and behavior of white-throated sparrows revealed a mutation in chromosome 2 that makes it impossible for same-color-morph birds to reproduce. The birds seem to know this and only look for mates among birds of the opposite color. Instead of half the population as possible mates, fellow researcher Christopher Balakrishnan points out that “One individual can only mate with one-quarter of the population. This bird acts like it has four sexes.”

  • White-stripe Male
  • Tan-stripe Male
  • White-stripe Female
  • Tan-stripe Female

A system of four sexes is quite rare and there’s a reason. As Balakrishnan says, “it is evolutionarily unstable and one of these alleles will ultimately go extinct.”

White-throated sparrows have declined 69% in the U.S. over the past 50 years and overall (including Canada) by 33%. Are they declining because of habitat loss? window kills? Is their four-sex system also taking a toll? If so they’re probably the only species with that challenge.

Read more in these two articles where I obtained the quotes above: IFLScience: Meet The Sparrow With Four Sexes and NATURE: The sparrow with four sexes.

Hand Feeding The Birds

27 December 2022

When Michigan photographer Jocelyn Anderson (@JocAPhotography) takes a walk in the park she brings her camera and a pocketful of shelled peanuts, sunflower seeds and suet nuggets. While balancing her camera she films the birds eating out of her hand in beautiful closeups.

Before last week’s cold snap the birds were very hungry and very active as seen in the screenshot above and her video below. (Videos are in slow motion.)

A male red-bellied woodpecker arrived alone. As he lands you can see the pale red patch on his belly that gives him his name.

Days later it was too cold for bare hands so she offered the food on her mitten.

Best Feedercam!

23 December 2022

Severe cold weather has people huddling indoors and birds flocking to feeders across North America. If you don’t have a feeder you can still watch birds online at Ontario Feederwatch, one of the best around.

Tune in to see the usual suspects — cardinals, chickadees, blue jays — and some boreal specialities including common redpolls, pine siskins, pine grosbeaks (above), evening grosbeaks, and crossbills.

Click here or on the screenshot below (with 5 pine grosbeaks!) to visit Ontario Feederwatch at All About Birds. It’s my favorite feedercam.

By the way, if you don’t see a bird when you tune in, just wait. If you hear them chirping in the background they’re about to arrive.

A Rare Bird at Any Time of Year

16 December 2022

A yellow-throated warbler (Setophaga dominica) would not be rare in Pittsburgh in early May but to see one in Canada in December is amazing.

This bird was photographed in St. John’s, Newfoundland on 9 December by Phillip (Felip1).

It’s not a very sharp picture but enough to identify him: a Yellow-throated warbler. He showed up for some suet early this morning.

I was half-expecting him. He had been visiting a suet feeder a couple of hundred metres away from us a few days ago. And one of the flickers had chopped up lotsa suet for him from the suet holder above. Those flickers are pigs but the other birds appreciate it.

Even though it is mid-December, the weather’s been mild and there are a half-dozen warblers who have apparently decided to try their luck to spend the winter around this town, St. John’s, Newfoundland, when all their relatives decamped a couple of months ago for more southern climes.

Felip1: Late Warbler, 9 December 2022

Pennsylvania is typically the northern limit of the yellow-throated warbler’s range and it’s a short-distance migrant to Florida and the Caribbean. St. John’s, Newfoundland is not even on the map (red arrow points toward it) but Newfoundland is about as far as Florida if you’re migrating from PA in the wrong direction.

The presence of this bird, one of half a dozen warblers in St. John’s in December, might be an after effect of Hurricane Fiona … and might not.

In any case its splash of yellow is a happy sight on a dreary day.

Robins On The Move

2 December 2022

In mid November hundreds, perhaps thousands, of American robins (Turdus migratorius) were in the east end of Pittsburgh but left abruptly when the weather dropped below freezing on November 18th. By the 21st it was 17 degrees F and the robins were long gone.

Robins can cope with cold weather but not with frozen ground so they stay just south of the freeze line as winter approaches.

Those that nest in Canada and Alaska may leapfrog over the local slowpokes who wait for truly awful weather.

eBird distribution maps for June-July and December-February show that robins vacate the north to populate temperate zones in winter. June-July is dark purple with robins everywhere except for the hottest southern U.S. In Dec-Feb they’re concentrated in the Pacific Northwest and the Southeast including Florida.

Robins were on the move here in November. Now they’re south of us, wrapping up.
