Quebec chronicles – passerines with yellow and green colors, part 2

My last “bird blog” from Quebec! The passerine birds that we admired during our trip there included the vireos and grosbeaks. But I saved one warbler for this blog since I often had to look at the photos to be sure which species I had seen. The Tennessee warbler (Oreothlypis peregrina) could namely be mistaken for a Philadelphia vireo if it goes by quickly and you are not an experienced or expert birder. (It also can be easily mistaken for a female black-throated blue warbler.)

This very charming bird seemed to be everywhere we visited in great abundance. I had seen one last summer in North Carolina; now I got to see dozens of these little beauties.

 

 

Like the bay-breasted warbler, it specializes in eating the spruce budworms and hence its numbers wax and wane along with the availability of this food source.It was gleaning in all kinds of trees as well as along the shore, however, and obviously also looking for other types of food.

 

Besides insects, this bird also likes nectar and gets it by piercing flowers at the base of their stems on trees.

 

On the one day that it rained, I saw one waiting out the shower in a yard tree. On another morning, I surprised a Tennessee taking a bath in a little puddle formed by a streamlet flowing from a yard to the street where we were staying. The bird was still wet but fluttered its wings and dried off very quickly, looking fresh and pretty for a possible new partner.

 

 

The Philadelphia vireo (Vireo philadelphicus) is another attractive avian. It has the same coloring as the Tennessee warbler but has a bit of a hook at the end of its bill.

Like the Tennessee warblers, they migrate to Mexico and environs during the winter. Their meals of choice are insects and some berries (e.g., bayberry and dogwood). The birding websites and Wikipedia do not have anywhere near the same amount of information on this species as some others, so they likely have not been studied very much.

 

One day as I walked a path in one of the nature reserves, a Philadelphia vireo followed me a bit as I walked, finally perching on a nearby branch and fluffing its feathers. S/he looked like someone showing off a party dress.

 

 

The blue-headed vireo (Vireo solitarius) is a much darker bird, with olive-green feathers, a blue-gray crown and white “spectacles”. I haven’t seen many in North Carolina and I only saw two in Quebec – decidedly a somewhat shyer bird than many of the others that crossed my paths.

Finally, some birds that gave me very good looks were the stunning evening grosbeaks (Coccothraustes vespertinus).

These birds only very rarely show up in the Piedmont area of North Carolina in the winter but last year I had the privilege of having a male and two females visit my feeders for one day. During this trip, we visited a neighborhood where a whole flock was busy feeding in the trees.

The males have rich deep yellow coloring offset by white and black accents on their heads, wings and tails. At one feeder, I was surprised to see one male apparently feeding another. It turns out that they may be territorial in wintertime around food sources but in the spring and summer, they are quite social and tolerant because there is a greater abundance of insects, buds, berries and seeds.

 

 

The females are much more muted in color with light yellow highlights against a pale gray background but they also have beautiful patterned black and white wing feathers. Their light yellow-lime-green beaks serve well to break apart seeds.

 

 

 

The oldest evening grosbeak on record reached the age of 16 years, 3 months. It appears that their numbers may be decreasing, although the population as a whole is not yet at risk. I look forward to another “irruptive” year, when they expand their winter territory – perhaps I’ll have a couple unexpected visitors again!

The beautiful “baker” bird

Recently, I’ve had the good fortune to observe a small bird at close quarters that I had only seen in a couple glimpses in the past, the ovenbird (Seiurus aurocapilla). Like the ruby-crowned and golden-crowned kinglets, this little avian also has a stripe atop its head. Like the golden-crowned kinglet, the stripe is always visible and orange in color, blending in nicely with its other muted brownish and cream colors.

 

The ovenbird gets its name from the shape of its nest, which is built on the ground in a shape reminiscent of an outdoor or Hopi oven. It is domed and has a side entrance and can be difficult to see.

The ovenbirds spend the winters in the Caribbean region and Central America and then come North for the summer breeding season. My sightings of the singing male have been at our local nature reserve, Mason Farm Biological Reserve, where I volunteer as an invasive plant eradicator and sometime planter of native flowers.

 

The male sings a three- to-five note call in the spring as part of his courting behavior and the call varies among individuals. When males are in neighboring territories, they will sing together in duets and it can be difficult to know how many birds are singing.

   

The sound is so loud that you expect to see a much larger bird and his song inspired poet Robert Frost to dedicate a poem to him.

 

If he is sitting on a branch, you can eventually find him but it can be a challenge since they prefer to reside in forests with heavy canopy cover so that it is fairly dark.

 

   

Once you see him, you may be able to watch for a while as they don’t seem to be very wary of people. This individual let me observe as he groomed on a low tree branch, pausing now and again to let out a few notes.

  

   

These birds prefer areas with heavy leaf litter for their homes – the leaves provide cover for their ground nests and they blend in really, really well as they scurry about foraging in the leaves for insects, worms and snails to eat. Both the females and males participate in feeding the fledglings until they can fly at about 30 days.

When they emerge into a patch with a bit of sunlight filtering down through the leaves overhead, you have a bit better chance to see them. Otherwise, you may end up staring at ground cover until you catch a bit of movement and can zero in on the motion to see them.

 

Photographing the bird is a challenge since they spend their time in areas with so little direct light. My first photos were a bit dark, but then I increased the ISO on my camera considerably (a tip from fellow photographer, Mary – thanks!) and the photos were a bit better. Still, the somewhat darker photos reflect the environment in which you discover these little troubadour warblers. Now that I know where to look for them, I hope to see them more often in years to come.

Late arrivals and late departures

Since a ruby-crowned kinglet (Regulus calendula) began visiting my suet feeders several years ago, I’ve looked forward to his arrival each autumn so that I can watch him at leisure during the winter months. This past season, however, I began to fear that he had decided to go elsewhere or, more sadly, might have passed away and wouldn’t be coming around again. I did see members of the species at the Haw River in late November and one was feeding on seeds to my surprise.

Then, finally, on the 26th of December, Rudy turned up at my feeders – weeks later than usual but to my great delight! And where did he go for a bite to eat? In the past, he loved my suet but now he, too, was feeding at one of the seed feeders!

Shortly thereafter, I discovered I now had two ruby crowns in residence as they began vying with one another to claim the suet area as their territory. After thinking that I would have no jeweled visitor this winter, it turned out I had two, leading to a happy dance as I gazed out of my living room window.

   

The golden-crowned kinglets (Regulus satrapa) have a single feather covering each nostril; this doesn’t appear to be the case for the ruby crowns. Their tongues are often in sight when they open their mouths in anticipation of getting a bite. I wondered if the tongue is sticky to help them snatch food while hovering; an online search did not net me any references about kinglet tongues, however.

Normally, these hyper-active tiny birds seek insects and arthropods as meals, including spiders, pseudoscorpions, aphids, bees, wasps, beetles and ants. But my home-made suet has proved to be a big draw (also for other birds with whom they must compete for space).

 

The ruby-crowned kinglets will often hover in front of a feeder, sticking out their tongue to snag a bit of suet before they fly to a perch.

As winter progressed, it looked like the yellow-rumped warblers (Setophaga coronata) decided to copy their style, also hovering and snatching on occasion.

 

I decided to leave the dry stalks of the scarlet mallow and butterfly bush in place this past winter so they had perches close to the feeders. They made a nice “studio” for some portraits!

After a while, since there was a lot of traffic at the feeders, I began smearing suet on the mallow stalks, which proved to be a big hit. The ruby crowns alighted and fed calmly, a big change from their usual frenetic pace. (A few other birds also enjoyed this option, including the Eastern bluebirds and yellow-rumped warblers.)

 

Sometimes, they went through a bit of head contortion to snag some of the treat.

 

 

 

 

These kinglets surprised me again in January when they began visiting the peanut feeder, too. I watched as they pecked off tiny bits of peanut; I suspect they also might have been looking for ants or other insects around the nuts.

 

 

 

When it rains, these little avians can look quite bedraggled! But they didn’t appear bothered by the snow flurries.

Normally, these birds are in what seems to be constant motion, scarcely stopping for a second in their quest for food. A large privet bush near my feeders, however, has become a resting and hiding spot for them. (Yes, I know, privets are invasive plants and should be removed but this particular shrub provides a get-away for the feeder birds when the sharp-shinned and Cooper’s hawks fly in for a raid and the catbirds love to build their nests in this particular site.)

    

  

I continued seeing ruby crowns during my nature walks, although not as reliably as in my own yard. They were in residence at the Jordan Lake woods and a small wooded area near Chapel Hill’s Senior Center.

 

 

One day at the Haw River, I witnessed a territorial dispute between two males who were claiming certain trees as their own.

 

I stopped seeing the ruby crowns at my feeders around the end of March and assumed that they had embarked on their migration up North for breeding season. On 9 April, I was surprised to see one in the woods bordering Jordan Lake.

On 18 April, one appeared in a cedar tree in my yard.

And then on the 22nd of April, I spotted one high in the leafy branches of a willow oak in my front yard. I’m guessing that perhaps this bird was stopping for a rest as it traveled from further South on its way up North; I didn’t see it visit the suet feeder.

 

 

I miss my little kinglet companions in the spring and summer; hopefully, they won’t wait so long to appear again later this year.

 

Back to blogging with the golden crowns!

Litter boxes scrubbed, bird feeders filled, other chores waiting but I’ve decided to end my blogging hiatus on this rainy and somewhat gloomy Sunday morning. This and my next blog will feature two of my favorite birds and then I hope to treat you with a nesting saga as spring is well underway.

With a lovely ruby-crowned kinglet visiting my yard every year for the past four years, I’ve developed a particular fondness for this tiny avian species. This past autumn and winter, my partiality expanded to include their jeweled cousins, the golden-crowned kinglets (Regulus satrapa), who seemed to have favored our geographical area with an irruption (an ecological term for a sudden increase in an animal population). Whereas in previous years, I felt lucky to catch a glimpse of a golden crown during their months-long stay in North Carolina, they appeared to be everywhere this past winter and in full view to boot.

 

The golden-crowned kinglets are about the same size as the ruby crowns and similar in overall body color except that they also have a black eyebrow stripe.

While the ruby-crowned males only flash their red crests when mating or upset, however, the golden crowns have a permanent yellow stripe atop their heads.

 

         

The male golden crowns can sometimes be distinguished by the fact that there will be a hint of red in their golden crest.

         

Like the ruby crowns, these little insect foragers are in constant movement as they scour branches, shrubs and plants for a meal. Their varied diet includes beetles, flies, crickets, butterflies, spiders, and bees and wasps. In the winter, they will also eat some seeds.

     

Searching for the insects often means they hang upside down from branches as they look at the underside and in crevices for their next bite to eat.

 

They also hover mid-air to snatch an insect or fly.

The golden crowns sometimes sit still a bit longer than ruby crowns so that you have a chance to get off a few photographic shots before they resume their dietary searching. And this year, one of those photos placed me among the winners in a small local competition.

These birds are not much bigger than hummingbirds, but like the hummers, they also undertake a long migration twice yearly. Their winters are spent throughout North America but for breeding they travel to the far North and mountainous Northwestern areas of this hemisphere.

This year, many places had mild winters but if they arrive in the North before spring-like temperatures arrive, they are able to survive nights as cold as –40 degrees; sometimes, they huddle together to keep a bit of warmth. Their lifespan is several years, with the oldest recorded golden crown being a banded male who was at least 6 years and 4 months when he was recaptured in Minnesota in 1976.

       

 

This species prefers life in coniferous forests but it seems if a few spruce and pines are around, they will settle in. I saw them in a small and somewhat sparsely vegetated area near a senior center, an arboretum, along the Haw River, and in the woods and bogs of various nature reserves.

 

 

In the United States, the number of golden-crowned kinglets declined 75% between 1966 and 2014. Habitat loss has contributed to this. However, spruce reforestation in the Eastern USA may have contributed to a more recently seen increase in numbers of kinglets. I’m very glad that they are not (yet) an endangered species and I hope we get to see them a lot next winter, too!

Warbler watching and migration – a shared pleasure for birders!

black-and-white-warbler-i77a3458-maria-de-bruynAutumn migration in North America has been underway for some weeks and our bird populations in North Carolina are changing in composition. Some birds stay year-round – for example, I see robins, blue jays, Carolina wrens, Carolina chickadees and tufted titmice in all seasons to my great delight. However, other birds who have been here since spring are now getting ready to leave for a southerly jaunt to a place that will be warmer for them in winter – most of the ruby-throated hummingbirds and some gray catbirds have departed already. (I have had a catbird stay year-round but others leave.) Many black and white warblers (Mniotilta varia) will be leaving, too.

american-redstart-i77a4367maria-de-bruyn-resThe Nature Conservancy has noted that the autumn songbird migration is one of the top four migrations in this state. The Audubon Society has even published a guide to this migration and when certain species usually begin their travels. (Left: American redstart male)

 

This seasonal event means that dedicated birders make special efforts to visit places where it’s likely we’ll see warblers. Many of North America’s 50 species don’t eat seed or suet, so you won’t find them visiting your feeders often. I have found, however, that pine warblers (Setophaga pinus) and yellow-rumped warblers (Setophaga coronata) are pretty social and those who are here for the winter are already joining my “regular” birds at feeding stations. The pine warblers especially like suet (female left, male right below).

The yellow rumps are still looking around a lot for insects; this one snagged a skipper butterfly.

In the autumn, many of these songbirds no longer have their beautiful breeding plumage, which is often so distinctive that you can identify them easily, especially the males. I was lucky enough to see some of those beauties during spring migration as well as in the summer for the ones that spend the warmer months here.

The warblers’ non-breeding coloration is frequently duller and drabber than their breeding plumage. Often only experienced birders can tell some species apart on first sight. Added to that is the fact that young birds don’t yet have their adult plumage and the immature males often look just like adult females. So it is a challenging time for identification, especially for me, but an exciting time for discoveries.

 

blackpoll-warbler-i77a1289-maria-de-bruyn-resGetting photos of these lovely birds can be tricky since they move about a lot in search of their insect meals. It is ultimately the pursuit of those culinary delights that leads the warblers to migrate South, since the insect population declines dramatically in areas with cold weather.

Nature photographer Mary had discovered a spot where the warblers could bathe in a relatively protected fashion; she kindly shared the location with some of us and a number of avid birders sat with her for hours waiting for the birds to appear. Some of our more “common” avian friends used the site, too, including a gray catbird (Dumetella carolinensis) and a brown thrasher (Toxostoma rufum).

A Northern waterthrush (also a warbler, Parkesia noveboracensis) found the spot enticing.

The trees around the water hosted birds as they looked for insects, like the black-throated blue warblers below (Setophaga caerulescens), seen a few weeks apart.

A female American redstart (Setophaga ruticilla) spent time working the shrubs surrounding the creek with some success.

The male redstarts hopped about the branches and rocks hanging over the creek for a while before venturing below to bathe.

They also didn’t mind sharing the space with each other (or sometimes other species)..

The Magnolia warblers (Setophaga magnolia) did the same, giving me some good looks and making my first in-person sighting of this species (lifer!) quite special.

A male hooded warbler (Setophaga citrina) made a brief appearance one day, followed by some female and male common yellowthroats (Geothlypis trichas).

Another water body that provided me with some excellent views of warblers was the Haw River. In the small town of Bynum, a bridge crosses the river and gives birders a great vantage point to see birds in the tree canopy close to eye level. There I was able to see two more lifers a couple weeks ago – the first was a bay-breasted warbler (Setophaga castanea).

blackpoll-warbler-i77a1315-maria-de-bruyn-resThis beauty was followed by another that had me confused. At first, I thought I was seeing a kinglet but this bird was a bit large and then as I got closer looks, I realized it looked like a bay-breasted warbler but had yellow feet. A search on the Internet showed I had seen a blackpoll warbler (Setophaga striata), likely a non-breeding male. Experts on an American Birding Association Internet site confirmed the ID for me.

black-and-white-warbler-i77a7204-maria-de-bruyn-resMy migration warbler watching culminated with some exciting finds in my own yard. I was surprised by several I hadn’t seen at home before, including common yellowthroats, a black and white warbler looking for insects in my willow oak and a gorgeous Northern parula (Setophaga americana), who even came to my feeders before pursuing a caterpillar in a Rose of Sharon nearby.

I’m now hoping to see some birds that breed further North during the summer arrive here for their late fall/winter/early spring sojourn, such as a ruby-crowned kinglet who has spent time with me each winter for the last three years. Next time I’ll share some of my pollinator sightings with you, in the hope you find them as fascinating as me. Have a nice day!
