Winter wonderland – sharing and spats at the feeders

I thought I had published this blog in early February and just discovered that I had only saved a draft. Since we had snowflakes last night (in April!), I’m going to go ahead and post this now – a break in the series about Costa Rica! When the snow began falling during our day of one-foot accumulation, the feeders were inundated by some of the dark-colored bird species who tend to come in crowds. At first, they were peacefully sharing space.

 

  

Although I sometimes have a couple dozen red-winged blackbirds (Agelaius phoeniceus) at the feeders, during the storm only one pair showed up for a brief visit and the other birds left them alone.

 

The mourning doves (Zenaida macroura) often share feeder space with other birds, including those that are smaller than they are.

The common grackles (Quiscalus quiscula) are known to other people as domineering birds at the feeder, but those in my yard have always been polite, even though they seem to have a permanent expression that expresses anger.

 

 

The brown-headed cowbirds (Molothrus ater) sometimes share space nicely and sometimes fuss at one another as they vie for a good perch. They don’t try to chase off other species though and are not apt to “yell” at other birds.

The birds who do “yell” are the European starlings (Sturnus vulgaris). Young ones yell at their parents after fledging, begging to be fed. Adults yell at each other when they are trying to all crowd together onto a feeder. And adults yell at other species to drive them away so they can have all the space for themselves.

At my feeders, however, they have found their match in the male red-bellied woodpecker (Melanerpes carolinus). One day, I watched as they managed to intimidate him for a few minutes, but he then returned to the feeder and refused to give up. Now he is no longer frightened of them and stands his ground when a starling does its best to make him move.

    

It turns out that studies have shown that the red-bellied woodpeckers are the birds most apt to resist attempts by other birds to displace them from feeders.

The red-bellied woodpecker also was not intimidated by me at one point. He doesn’t like it when he flies in and notices at the last moment that I am sitting or standing on the porch; often he will swerve away and wait for me to leave. During the snow storm, however, he decided to display his displeasure with my close presence, both from a frontal and dorsal view!

 

  

      

 

I guess that the little bird spats do make for sometimes more interesting birding observations. Seeing the tiny ruby-crowned kinglet (Regulus calendula) warning off a rival a few days before and after the snow melted did show off a gorgeous and brave little bird.

 

 

I’m looking forward to seeing what the springtime observations of animal behavior will reveal.

 

Winter wonderland – the bigger and colorful birds

In this second-to-last blog of the snowstorm series, I’d like to feature the bigger and colorful birds who demonstrated how they adapted their feeding habits to the prevailing weather. The Northern cardinals (Cardinalis cardinalis) actually didn’t change their behavior that much – they looked on the ground for fallen seeds and spent plenty of time at the feeders.

They spent some time in the snow-laden trees looking lovely, too.

  

  

The Eastern towhees (Pipilo erythrophthalmus) usually spend their time foraging underneath the feeders in search of fallen seed and they continued that behavior during the snowstorm. Unfortunately, the female was carrying a tick; I had already seen a robin and a junco with ticks on their faces – this may mean that the coming spring and summer will be an especially bad tick seasonal period for us.

 

The beautiful brown thrasher (Toxostoma rufum) looked both on the ground and at the feeders for his meals. Despite his size, s/he never bullied any other bird.

 

 

 

   

The remaining juniper berries on the red cedar trees (Juniperus virginiana) attracted the blue jays (Cyanocitta cristata).

The Northern mockingbird (Mimus polyglottos) was also seeking food there.

 

 

 

 

The cedar waxwings (Bombycilla cedrorum) and American robins (Turdus migratorius) had already been eating the juniper berries in the autumn; the waxwings had been by about a week earlier but now the robins were all over the trees, shaking off accumulated snow to get at the remaining fruit.

 

 

One robin looked as if s/he might have lost some outer feathers but it didn’t seem to affect her balance or flight. Occasionally, a robin also visited the meal worm feeder.

  

On the days following the big snowfall, as the snow melted more and more, the robins began eating it. During a previous snow event, they had joined the cedar waxwings on the roof of my house to get their drinks that way; now they were taking the snow from the trees.

They weren’t the only ones taking advantage of the opportunity. The Northern flicker (Colaptes auratus), who did not visit the feeder, spent a lot of time in an oak tree near the feeders eating snow.

 

  

There were a few birds that visit my yard who didn’t show up during the snow. They included the American crows and the hawks who often make the birds scatter from the feeders: the Cooper’s, sharp-shinned, red-tailed and red-shouldered hawks. They must have been looking for food elsewhere.

Some birds may have also avoided the feeders because of the large number of competitors who showed up, a feature of the next and last blog in this series.

Winter wonderland – the smaller and medium-sized birds

Oddly, during our January snowstorm, the brown-headed and white-breasted nuthatches did not visit my bird feeders – that was unexpected as they really do like the sunflower and other seeds, as well as the home-made suet. Other smaller birds did appear, however, and they filled up on the provided food since finding insects was almost impossible during those days.

The Carolina wrens (Thryothorus ludovicianus) were fans of the dried meal worms and at one point, I put out an extra tray of these treats on the dry front porch. Other birds are more reluctant to come onto the porch so they had a nice quiet feeding area, although they also spent time perched on the snowy bushes and feeders.

  

  

 

The Carolina chickadees (Poecile carolinensis) worked their way in between the other birds to reach the feeders, sometimes waiting patiently on a feeder pole for their turn.

The ruby-crowned kinglets (Regulus calendula), of which I have two visiting the feeders, were happy with the home-made suet. Occasionally, I smeared a bit of suet on dried flower stalks and they would perch there to snag a bite to eat. Other times, they just waited on a twig until the yellow-rumped warblers had vacated the area so they could eat in peace.

    

While the downy woodpecker (Picoides pubescens) is slightly larger, they are like the small birds in being somewhat hesitant to approach feeders if there is a crowd. Once on a feeder, they will feed and then hang on to take a look around.

  

The dark-eyed juncos (Junco hyemalis), who have an understated quiet beauty, were looking for meal worms.

    

The similarly colored tufted titmouse (Baeoloophus bicolor) often zoomed in on its target of the fruit and nut feeder without taking time to perch first.

The American goldfinches (Spinus tristis) didn’t come round very much, only snacking on some sunflower seeds. Since they often feed on the crepe myrtle tree seeds, they were likely finding enough food there.

The Eastern bluebirds (Sialia sialis) came in spurts of activity. They always look rather bedraggled when they get wet with snow or rain and perhaps prefer to stay drier under branches until there is a break in the falling moisture. Even wet, though, they are still attractive to me.

The smaller/medium bird group was rounded off by the house finches (Haemorhous mexicanus). The females were looking especially nice. The finches never have spats with anyone and are among the most peaceful feeder birds. Not everyone was like that, however, and the next blog looks at the rowdy ones.

 

 

Winter wonderland – sparrows and warblers

Yesterday, as I walked through my yard, I was surprised to see groups of daffodils sticking up their heads; it seemed rather early to me but last year we had early signs of spring as well. It is a big contrast to our weather conditions less than a month ago, though. On the 17th of January, our town was surprised by 11-12 inches of beautiful, powdery snow.

  

  

 

While our southern area often has a couple instances of (light) snow and/or an ice storm in the winter, our climate is generally fairly mild and temperatures in the 50s and 60s Farenheit are not uncommon during winter. So the brief but heavy snowfall was quite an event; our streets were empty of traffic as everyone stayed home and watched the falling flakes.

Some people built snowmen, others went sledding and walking, and some of us spent hours filling our bird feeders and watching the birds. I also made an attempt to photograph some frozen bubbles, which was very challenging since it was windy during the entire winter weather event.

  

The snow began slowly melting a bit the next day, which made some of the icicles on the house elongate to a length of almost 3-4 feet, but it wasn’t until Friday and Saturday that the snow and ice really started disappearing.

My yard looked beautiful, but I spent time on the 17th repeatedly knocking snow off the bird feeders and heated birth bath so that the birds could reach the food and water.

  

   

Although I saw a couple squirrels and the white-tailed deer (Odocoileus virginianus) also came by, I didn’t see other mammals like chipmunks, raccoons, opossums. But I had 25 different bird species come by on Wednesday and Thursday; on Friday and Saturday, two more species came by. I’d like to share some snow day photos of them all in this and the next few blogs.

First up are the sparrows and warblers. The chipping sparrows (Spizella passerina) usually get their seed from the hanging feeders in the front and back yards but now they were looking everywhere for a bite to eat. I had strewn some seed on the ground and they began looking there.

One found a trove of food and another came by asking to be fed, a request the first sparrow accommodated quite sweetly.

 

 

The white-throated sparrows (Zonotrichia albicollis) have an opposite feeding strategy, usually feeding on the ground and occasionally venturing up to a feeder. They, too, searched under the snow for some food.

 

The pine warblers (Setophaga pinus) tend to be rather shy; only very rarely does a pair visit together. Mostly, one shows up at a time; their beautiful yellow color was really highlighted against the white background.

 

The pine warblers did have to brave a bad-tempered bird to get to the feeders. One of the six resident yellow-rumped warblers (Setophaga coronata) has become very territorial, chasing away some other yellow-rumped warblers, the ruby-crowned kinglets and the pine warbler – in other words, the birds his size or smaller. He allows a couple other yellow-rumps to feed peacefully and I think perhaps they are his family members so that he tolerates them. He didn’t stop the other small birds from coming around, however, as we’ll see in the next blog.

 

My pond and the cycle of life

Undergoing cardiology exams can bring up thoughts of mortality and a life lived; perhaps they also made me more attentive to the cycle of life in my yard, particularly in the vicinity of my backyard pond.

Several years ago, a local garden center went out of business and they had a 175-gallon black plastic pond for sale. It was a good deal, so I invested in it and then had to dig a large hole in the rocky Piedmont clay ground of my backyard (with a bit of help from a neighbor teen). At a certain point, the ground was so hard we couldn’t penetrate it with shovels so the pond now sits a bit above ground level; the rocks I piled up around it have offered a home to Eastern chipmunks (Tamias striatus).

 

I transferred some of my beautiful koi and goldfish from a smaller pond, only to have a great blue heron (Ardea herodias) come by to clean them all out.

On the recommendation of the garden center staff, I had positioned a heron statue by the pond – they said herons don’t like competition, so the intruder would keep flying when s/he saw the one by the pond. It didn’t take long for the bird to figure out the stationary bird was not real, however.

After the heron had eaten all the koi and goldfish, I still had some tiny baby fish. At first, I thought they were from my now deceased koi but apparently the intruder heron had had fish eggs on its feet from a nearby natural pond and left them behind. So for a time, I had unidentified native fish in the pond. They were extremely shy, however, and I only got a brief look at them when they surfaced early in the morning; as soon as I came near, they dove down under the water plants (no good photos).

Then some green frogs (Lithobates clamitus) moved in this past summer and ended up being extremely prolific reproducers. Before I realized it, there were at least 500 tadpoles in the pond!! They were eating the fish food and at the same time I noticed that I wasn’t seeing the fish at all anymore. Going online, I found out that tadpoles will eat fish – their sheer numbers had to have spelled doom for the fish.

 

 

I collected lots of the tadpoles, gave some to a friend for her water feature and released hundreds into the local creek (they are native animals after all). A few of the tadpoles grew into frogs and the pond became a residence for some very loud croakers.

 

  

The next chapter in the story came a couple days ago. I had seen a pair of red-shouldered hawks (Buteo lineatus) visiting my yard recently. I thought they were after the chipmunks, numerous squirrels and songbirds populating the area. The other day, however, one hawk took up a position in the crepe myrtle tree next to the pond and just sat there calmly not bothering with any of those creatures. Numerous Northern cardinals (Cardinalis cardinalis) perched in the tree above her and many other species of birds were at the nearby feeders;  none of them were concerned at all with the hawk’s presence. The squirrels didn’t seem perturbed either.

She sat fairly still and I took some photos through my kitchen window. Then I ventured out into the backyard, sure she would take off as I left the porch steps. But Ms. Hawk just sat there, sometimes stretching a leg or engaging in a little grooming.

     

   

Occasionally, she looked up but often her gaze was fixed on the area around the pond.

She would stare intently down at the ground – I thought she might have spotted one of the pond chipmunks.

Then after a while, I noticed her shifting her stance – suddenly she plopped down into the pond with spread wings. It happened too fast for me to get out from behind dried plants to get a good photo, so I watched as she climbed out of the pond. Then it became apparent what she had been hunting – she had caught one of the green frogs.

  

It looked like she bit its head to kill it as soon as she got on dry land; the frog wasn’t moving.

Then she spent time ruffling and shaking out her feathers which had gotten a good soaking.

She spent a little time looking around and then abruptly took off with her prize, closely followed by another red-shouldered hawk who suddenly swooped in.

He chased her but she got away with her meal and he ended up sitting in a neighbor’s tree, somewhat disgruntled with his failed thievery attempt.

  

Ms. Hawk returned yesterday and spent quite a bit of time in a high tree surveying the yard and gazing down at the ground. Red-shouldered hawks sometimes eat birds, such as sparrows, doves and starlings (which are all numerous around my feeders) but more often they go after snakes, mice, toads, frogs, lizards and small mammals such as voles and chipmunks. They will also eat insects and earthworms. Since I’m leaving the leaf litter, there are undoubtedly more insects hiding there than in neighboring yards. I’m not sure what Ms. Hawk is seeking in my yard, but I hope she doesn’t get all the pond frogs. In any event, I’m sure new ones will find the water in the spring and in the meantime, I have a beautiful bird of prey to watch this winter.
