The Blue Jay Forecast

Published by under Migration,Songbirds

When folks wonder why blue jays are scarce they turn to the Internet and find my 2012 blog post “Have You Seen Any Blue Jays Lately?”   In the past two+ years 116 readers have commented on the status of blue jays where they live.

The most recent comments are on the absence of jays:  Where have they gone?  Why did they leave?  When will they come back … if at all?

Over the winter blue jays eat acorns, beechnuts, hazelnuts, hickory nuts and other mast (nuts).  Their range map looks as if they never migrate but they will leave if nuts are scarce.

How can we know if the blue jays will leave? Check the Blue Jay Forecast.

Every fall Ron Pittaway produces a Winter Finch Forecast for Canada based on the abundance of tree seeds in Canada’s forests.  The finches in his report eat a wide variety of seeds including spruce, fir, birch and mountain ash.  If food is abundant the birds stay home all winter.  In poor mast years they irrupt southward.  Here in Pennsylvania we wait for Pittaway’s forecast to tell us which species will visit us in coming months.

Blue jays depend on tree nuts too and they often move when the finches do, so Pittaway includes them in his forecast.  This year he says “Expect a good to heavy flight (many more than last year) moving westward along the north shorelines of Lakes Ontario and Erie because the acorn, beechnut, hazelnut and soft mast crops averaged low in northeastern, central and eastern Ontario.”

If you live in Ontario, don’t expect to see a lot of blue jays this winter.  Lots of them are in Pittsburgh — at least right now.  Guess where they came from.   ;)

Not Confusing

Published by under Migration,Songbirds

Hooded warbler (photo by Steve Gosser)

September and May are the two best months to find warblers in Pennsylvania, but in the fall many are confusing.  Adult males, like this hooded warbler, are not.

Confusing Fall Warblers got their name from four scary pages in the Peterson Field Guide to Birds where immatures and a few females are lined up to show their differences.  Hah!  They all look the same.

But I’ve learned a trick to overcome the problem.  The more you watch non-confusing adults the easier it is to identify their confusing “kids.”

Within each species the birds have the same body-shapes, feeding habits, perching styles and favorite locations (on the ground vs. thickets vs. treetops).  Often, the confusing birds have colors and markings that hint at their non-confusing cohorts.  Sometimes there’s one indelible clue — like the square of white on the female black-throated blue’s wing that matches the male’s.

Get some practice seeing adult male warblers on Steve Gosser’s new Warbler Page where he displays beautiful photos of Pennsylvania’s best.

Not confusing!

Waxwing Update

Cedar waxwing nestlings (photo by Marcy Cunkelman)

Remember the cedar waxwing nest I wrote about this month?  Marcy Cunkelman sent me an update this morning.

The eggs hatched more than a week ago and the parents have been busy feeding the nestlings.

All those trips to the fruit bushes have paid off.  Three healthy youngsters are tall enough now to be seen in the nest.  They have yellow wrinkled “baby” beaks and crests that look like bad toupees.

It won’t be long before they fly.

Keep growing, little guys.  Your”hair” will look better soon.

Hummer Time

Published by under Songbirds

Ruby-throated hummingbird (photo by Steve Gosser)

Did you notice that the hummingbirds “disappeared” in June?  And that they came back in July?

Our ruby-throated hummingbirds really didn’t go anywhere.  They were busy nesting and gathering insects to feed their young.  Since they don’t feed nectar to their babies there was little reason to visit hummingbird feeders.

But now the “kids” are grown and the hummingbird population has surged.  Mom, Dad and the kids are jostling for space at the feeders. Males perch high on dead snags to protect their nectar kingdoms.  Steve Gosser captured this beautiful male on his way to a feast.

Once again it’s Hummer Time!

TBT: How Cowbirds Know They Are Cowbirds

Immaure brown-headed cowbird (photo from Wikimedia Commons)

On Throw Back Thursday (TBT)…

At this time of year most birds have stopped breeding and are starting to flock for the coming winter.  Many of us have noticed grackle flocks and soon, I’m sure, we’ll see flocks of brown-headed cowbirds.

The fact that young cowbirds flock with each other is a miracle in itself.  Every one of them was dumped as an egg in another species’ nest where they out-competed their foster parents’ young.   Imprinting behavior says they ought to think they’re members of the foster species, but they don’t.

How do cowbirds know they are cowbirds?  Click here to find out in this Throw Back Thursday article.

Bird Banding At Marcy’s

Hey! says this female northern cardinal on banding day (photo by Kate St. John)

Yo! says this wet northern cardinal.  She was about to be banded at Marcy Cunkelman’s last Saturday.

After a week of gorgeous weather July 19 brought all day rain.  At 7:00am Bob Mulvihill (lead bander), Matt Webb, Amy Feinstein and Becca Ralston were all set up for the National Aviary’s Neighborhood Nestwatch bird banding.  Here they are in a photo from Marcy. It was only drizzling at that point.

Banding Day at Marcy Cunkelman's, 19 July 2014, Amy, Matt, Bob, Becca (photo by Marcy Cunkelman)

I arrived around 7:30am and soon there were 14 of us under the shelters.  The birds were wet, we were wet, but we were all well fed at Marcy’s delicious buffet.   During downpours we closed the nets and watched the weather radar on our cellphones.

The target species were eight classic backyard birds — robin, cardinal, mockingbird, catbird, chickadee, song sparrow, Carolina wren, house wren — but Marcy’s yard had many more than that.

Highlights included this immature male northern cardinal. He’s being given something to bite so he’ll stop complaining.  This is safe to do with immature cardinals because they don’t have the gripping power of adults.  His bite is a tight pinch but not painful — I know from experience.  Look closely at the top of his beak and you’ll see a bulge on his upper mandible.  That’s avian pox, a common contagious ailment among birds. (Humans are not at risk.)  Bob said it looked like his pox was healing and would fall off.

Our Best Bird!   This beautiful male scarlet tanager was a big surprise because the nets were set up by the bird feeders and scarlet tanagers aren’t “feeder” birds.  They normally stay high in the trees eating fruit but the rain brought him lower, trying to stay dry.  (He was soaked just like we were.)  He was probably caught when he tried for the fruit on Marcy’s viburnum shrubs near the feeders.

Red-eyed vireos were caught for similar reasons.  Here are two males showing off their red eyes.

Becca stroked the birds to keep them calm.  This red-eyed vireo responded by bending over backwards.  Who knew they could do this!

Here Marcy holds a red-eyed vireo just before she releases it.  We were all as wet as the birds but happy to be with them.

The tally for the day was 67 birds.  It was a great day for bird lovers despite the rain.

Thanks to all!

Teenagers

Published by under Songbirds

Downy woodpecker "teenager" (photo by Marcy Cunkelman)

Songbirds grow up so fast that within days of fledging they aren’t babies anymore.

Suddenly they are teenagers — able to find their own food, almost independent of their parents, a little cocky and a little unsure of the world.

Marcy Cunkelman captured these photos of teenage woodpeckers in her garden.

Above, a young downy woodpecker looks like an adult except for the colors on his head.  He fledged with a splash of red on top but that will soon be replaced with black feathers and the red will move to his nape.  Meanwhile he shows off an intricate black-and-white pattern on his forehead as he looks calmly at the camera.

Below, a young red-bellied woodpecker has subtle colors on his face and head with dull gray cheeks and faint orange on his nape. He looks startled. “What is a camera?  Is it dangerous?”

Perhaps your backyard has more starlings than woodpeckers.  (Mine does.)  Click here to see what teenage starlings look like.

New Bird In Town

Juvenile European starling (photo by Emőke Dénes from Wikimedia Commons)

There’s a new bird in town with a brown body, faint stripes on his brown chest, black beak, black eye, and a little black mask.

What is he?  A juvenile starling.

He’s confusing because he’s not in the bird guide unless you know to look for starlings.  He doesn’t look like his parents but his behavior is the same as theirs.  The big hint to his identify, if he’s still at the begging stage, is that he won’t leave his parents alone.

You can hear him begging, “Churrrr, churrrr, churrrr.”

Click here for a story about him that I wrote in 2010.

Why Are Warblers Yellow?

Published by under Songbirds

Kentucky warbler (photo by Steve Gosser)

Many warblers have olive-green backs, yellow breasts and black feather accents.  Think of hooded, prairie, Wilson’s and Kentucky warblers like this one.  Why are so many of them this color?

Steve Gosser’s photo shows why.

By the time a warbler nests in North America, the leaves are out and the forest’s light is soft yellow-green.  Seen by a predator from above, the warblers’ olive color matches the dark understory.  From below their yellow breasts match the light filtering through the leaves.  Their black accent feathers break up the colors and look like shadows.

In the winter the warblers live in leafy places in Central and South America where they continue to match the habitat.

Yellow is camouflage.

Not Your Typical Backyard Bird

A pair of prothonotary warblers, Conneaut Marsh (photo by Shawn Collins)

This pair of prothonotary warblers at a nest box may give you the impression you can attract them to your yard if you install the proper box.

Not!

Surprising for a warbler, prothonotaries choose old woodpecker holes or nest boxes for their nests but they are picky about habitat.  They only nest in forested bottomland, flooded river valleys or swamps.

The male returns from Central America before his lady and places nesting material inside his selected site.  Often it’s over water.  When his lady arrives he hopes she’ll agree that he’s chosen the right place.  If she likes it she adds twigs, leaves, moss and rootlets to finish the nest.

You can’t convince this bird to nest in your back yard … unless your yard is a wooded swamp.

 

p.s. Thanks to Shawn Collins for the photo that sparked this topic.
