Who wants to eat?

First, let me welcome those of you who have become new followers of my blog – nice to have you reading here and I hope you comment on what you like! I am way behind on my postings for the blog but will try to remedy that. There are photos almost ready for a series on bird courtship and child-rearing, as well as some other non-bird topics, but various issues have been keeping me from completing the texts. Now that I have had to take my preferred camera in for repairs, however, I have a bit more time to work on the blog and a recent brief trip to Topsail Island is providing some almost ready-made postings.

The south end of Topsail Island has been eroded greatly by the Atlantic storms, including effects from Hurricane Irma. Where normally the beach sloped up gently to beautiful dunes, these have now been sheared off vertically and the sea grasses and other vegetation before the dunes have been swept away.

 

 

That is of concern as the sea turtles nest there; hopefully, there will be sufficient places for their eggs next year. There were far fewer shells on the beach but at low tide the swath of empty sand was very wide.

 

Mixed groups of birds were resting there in between ocean fishing expeditions. There were a couple immature common terns (Sterna hirundo) who were begging for food incessantly, but the adults pretty much ignored them, preferring to preen or settle down for a rest.

Some of the begging was pretty vigorous, accompanied by feather ruffling and shaking but I didn’t see any parents go off for food.

The sandwich terns (Thalasseus sandvicensis) were also resting but individuals took off frequently for a fishing flight. These terns are easily identifiable by the yellow tips on their black bills and their Groucho Mark hair-dos, a boon for people like me who are challenged in recognizing which shorebird they have before them. Sometimes, you could imagine a conversation taking place between them.

Hi! I’m back from fishing!

Didn’t take long, did it?

See, I got a fish!

Wanna smell it?

Not to your liking, huh?

Walking in circles around me won’t make it any different

I think I’ll go feed a young one!

There were two immature sandwich terns who were very persistent in asking for a meal.

Come on, Ma, I’m hungry!

I am really really hungry!

Oh yum, lunch!

That’s right, put it right here!

Thank goodness you brought me something!

I’m STILL hungry!

Perhaps the adult sandwich terns were accommodating to their young as they have a lot of experience in raising them – the oldest one on record lived in North Carolina and reached the ripe old age (for a bird) of 24 years and 2 months! (However, the oldest common tern on record was 25 years, so perhaps the sandwich terns are just more caring?)

The birds were quite entertaining to watch and I have more photos to share from that trip. I will try to intersperse them between postings on avian child-rearing. Have a nice day!

A cuckoo causing confusion and consternation, delight and distress….

In the spring this year, I and another birder had the uncommon pleasure of seeing yellow-billed cuckoos (Coccyzus americanus) courting at Mason Farm Biological Reserve. These birds often stay high in trees, hidden by leaves, so it is always a treat to see one of them out in the open. Seeing two together, as the male tenderly offered his lady love a gift, was an unexpected pleasure.

 

 

Also unexpected have been my more frequent sightings of cuckoos in my yard. Last year, I had caught a glimpse of one in a crepe myrtle tree; I thought it was a lucky fluke. This year, I began to see cuckoos in the large trees of my front yard more often, though frequently they were half hidden behind the leaves of the willow oak, red cedar and persimmon. I did hear their identifying calls so I knew when they were around but not in sight.

Then, this past Sunday afternoon as I sat on my front porch photographing birds and insects visiting my flower garden, I suddenly caught sight of a cuckoo flapping about on a makeshift trellis I had arranged around an oak stump where I hope Carolina jasmine and other climbing vines will create a pleasing area.

The spot is popular with chipmunks and Eastern gray squirrels (Sciurus carolinensis), as well as many smaller birds like Renee, one of the banded Carolina wrens (Thryothorus ludovicianus) living in my yard.

     

But to see a large cuckoo sprawled on the branches was unexpected and I feared that it had an injured wing after escaping from a hawk attack. I took a few quick photos. Then I approached to get a better look — the bird tried to flutter away but didn’t get far.

I ran inside to get a box and the phone number of a local wildlife rehabilitator. I left a message and managed to get the bird in the box, to which it protested vigorously. When I closed the top, it calmed down and then the rehabilitator returned my call stating that perhaps it was a fledgling – I said it looked like the wing was injured so she asked me to take a photo of it.

When she saw my point-and-shoot camera photo, she said it wasn’t clear whether it was a juvenile or not and asked me to photograph the beak. Young birds have a yellow or bright “lining” where the beak meets the face. This area is called the gape flange and in most birds, the color disappears as they age and the beak becomes firmer.

      

With a slightly better photo of the bird’s head and beak, the rehabilitator informed me that this was indeed a young bird. She also told me that the bird probably was feigning a wing injury to get the parents to come back more quickly with food! On her recommendation, I put the bird back on a stump by the makeshift lattice.

I knew about killdeer adults pretending to have a broken wing and dragging it on the ground to lead predators away from a nesting area. The yellow-billed cuckoo adults will also do this distraction display.

But I had not heard of fledglings engaging in this ruse. The rehabilitator said she had known of crow fledglings that kept this up a couple days, although she didn’t realize cuckoos would do this as she doesn’t get many calls about this species. But, she commented, “birds aren’t stupid; a free meal is a free meal.”

I kept checking on the bird and it stayed on the stump quite a while. Then it hopped down into the leaf litter and made its way over to some large rocks under a cedar tree with low-hanging branches. First, the cuckoo just hung out on the rock. And all this time, it kept that wing stretched out.

Then the bird lunged upward to get onto the branch. At this point, I seriously wondered whether it wasn’t injured after all, perhaps having fallen out of the nest and hurting its wing when it landed. It got a purchase on the limb and continued to keep its wing out. Then it fell off the branch.

       

After a short rest on the rock, the fledgling jumped up on to the branch again and stayed there. I went inside and returned periodically to check on him/her. About 3.5 hours from time I first saw him/her, the bird was still resting on the branch with the wing out. S/he was no longer wary when I came to look but viewed me calmly.

About 30 minutes later, I went back outside for another check and found the bird on the branch, but now with its wings both folded in towards its body. I was really glad that it appeared to be ok and hoped the parents would come for it. I had heard them calling earlier in the afternoon but never saw them approach the offspring, though this may have happened when I went inside for brief periods. And when I finally looked at the first photos I had shot in quick succession, I saw a couple where the bird had drawn in both wings to hop about, only to stretch out its wing later again.

 

When it was almost time for me to leave for a theater engagement with a friend, I went back out to check one more time and discovered my cuckoo friend was gone. I examined the cedar tree to see if it was further up, as well as the trees and ground all around, and could find no sign of him/her. I hoped that s/he finally decided to give up the display and just flew to a better place. I did check the area the next two days but did not see the bird again.

Then, this morning, a distressing finding started off my day. When I went outside, a neighbor boy was staring at the ground in front of my street-side willow oak. When I got there, the cuckoo lay dead at the street edge. He said he had seen the bird yesterday sitting on the road “with a broken wing”. I wish I had seen it – I don’t know if the bird had really been injured after all, was feigning an injury and then fell prey to a neighbor’s cat (which is what I think happened as its underside looked like it might have been in a cat’s mouth), or if something else occurred. In any event, it was such a sad discovery.

I buried the cuckoo while regretting how short its life was. I’m glad I don’t let my cats roam about anymore and I wish neighbors would also keep their felines inside, even though I know that birds might fall prey to a hawk or die because of a disease. But I wish I’d been able to help this beautiful young bird. My emotions tell me the cuckoos won’t return but my mind says they won’t avoid the yard because they lost an offspring. Time will tell.

 

 

 

Mama and Papa house wren to the rescue!

A few times each day, I walk outside with my 18.5-year-old cat, Jonahay, who is deaf and has some other ailments. He used to be an indoor-outdoor cat until I decided that it was better not to let him roam the neighborhood.

 

 

He rarely killed anything; he just wanted to mark his territory (which he still does) and occasionally he would catch moving things and bring them inside.

Thankfully, he didn’t bring me dead birds or animals; I did have to capture baby rabbits, chipmunks and a snake or two so they could go back outside. Now he just walks around and sleeps on the porch with me at his side; chipmunks and squirrels walk by him as they know he won’t chase them.

This afternoon as I was vacuuming, Jonahay came to ask for a walk, so I paused to take him outside for a few minutes. When we got to the side yard, I was surprised by a pair of house wrens (Troglodytes aedon) who were chittering vigorously and loudly in a cedar tree above me. They had not nested in my yard this year but do visit once in a while.

 

As I moved, they moved with me, continuously calling – their vocalization was very obviously directed at me, but I didn’t see any young ones anywhere so I wasn’t sure why they were so upset.

One of them – the male, I presume – only paused his calling for a few seconds when he groomed a little. I kept looking around for what might be upsetting them but didn’t see anything. Jonahay indicated we could go inside and the wrens had to let me leave.

 

As I took the vacuum cleaner into the kitchen, which opens onto a screened-in porch, I suddenly noted a few tiny feathers on the floor. If the wrens hadn’t been “yelling” at me, I might have just glanced down and thought they were bits of cat toy or fluff. But now I was more alert!

I called my two other (indoor) cats and they didn’t come, which was suspicious. Even when they look at animals through the windows and screens, they will usually react if I speak to them. When I entered the laundry room on the other side of the kitchen, there were Moasi (shown left)  and Ogi (right), sitting on the washer and dryer watching a juvenile wren perched on the window sill!

I don’t know how the bird got into the house. Likely, it had been early in the morning when I opened the porch door for a few minutes as I put out bird food, but I had not seen the bird on the porch when I re-entered. During the morning and early afternoon, I hadn’t noticed the cats chasing anything either so the mystery remains. I hadn’t been outside much with all my chores so perhaps those parents had been calling for him all that time.

In any event, I shooed Moasi and Ogi out of the room and proceeded to open the window. The little wren jumped into a plastic container near the window and that enabled me to easily move him/her to the open window. The bird waited a minute (enabling me to quickly get his photo) and then flew out to freedom – and obviously to a pair of anxious but effectively protective parents!

     

An evening at Bolin Creek

After a day waiting for four bluebirds to fledge (next blog!) and a health-care appointment, I decided to forego some chores and instead to spend some time at a bridge over Bolin Creek, a waterway in the local Carolina North Forest which belongs to the University of North Carolina. My naturalist friend Mary discovered that this spot is a favorite bathing spot for birds in the late afternoon and evening. Since the weather forecasters predicted rain most afternoons this week, I decided to make a quick foray there while I had the chance. I knew that photographing the wildlife could be difficult as the sky was dull, overcast and we were expecting a downpour but I was up for the challenge. And once in a while a bit of brightness emerged from behind the clouds to give me some encouragement.

At first, it seemed very quiet – no bird song or buzzing insects; I thought perhaps everyone was hunkering down in anticipation of a coming rainstorm. But then the sky lightened a bit and a handsome robber fly (Promachus) alighted on a nearby leaf. I think this is a red-footed cannibal fly; these insects look like little old men to me.

 

 

A little while later, there were suddenly three avian visitors. The female Eastern towhee (Pipilo erythrophthalmus) was the first to take a bath.

     

 

The blue-gray gnatcatcher (Polioptila caerulea) didn’t go to the water but flitted overhead.

 

The first of two American redstarts (Setophaga ruticilla) also hopped from branch to branch but eventually ducked behind some rocks to bathe.

A pair of damselflies hung out on the stream rocks; the blue-tipped dancer’s (Argia tibialis) dark purple made it look almost black in the twilight.

 

 

Then a beautiful female hooded warbler (Setophaga citrina) came by for a bath. Her golden feathers shone in the dark foliage and against the stream rocks.

 

 

 

A pair of gray catbirds (Dumetella carolinensis) came together but only one entered the stream for a thorough drenching of its plumage.

 

 

 

   

The redstarts returned but stayed on the branches as the daylight began leaking away.

A few other birds were in the vicinity but didn’t come near: American crows, Northern cardinals, a common grackle and two yellow-billed cuckoos. My visit ended when the sky really darkened — I started down the path in an effort to reach my car before the rain began. A Southern leopard frog (Lithobates sphenocephalus) crossed in front of me and paused in the grass, enabling me to get a quick portrait. And then a nettle of beautiful violet color called out for a photo, too. I made it to the car just as the first raindrops fell. Quite an enjoyable impromptu photography session!

Swallow sibling spats – who gets the food??

Mother Nature came through for me again a week ago, treating me to an interesting session of cliff swallow (Petrochelidon pyrrhonota) behavior. (I first thought they were barn swallows but then noted they didn’t have deeply forked tail feathers.) I had noticed the swallows flying high above me as I walked to a favorite birding spot where I hoped to see hummingbirds feeding on the profusely blooming trumpet vines. Instead, I got a lesson on how swallow siblings may interact.

Occasionally a couple birds would come very near one another in flight. My attempts to get good shots were however stymied by their very swift swooping.  As I came upon the structure where I would position myself for the next 80 minutes, I noticed five swallows sitting on a wire, all of them preening and grooming. It was only after taking multiple photos and one flying off that I realized the group included both adults and juveniles.

 

At one point, all but one flew away; he (assuming a male for convenience’s sake) was alone for a good bit of time. Occasionally, he would stretch his feathers or teeter on the wire; I wondered if he had hurt his wings and was therefore staying put, unable to fly.

It turned out that he was just waiting for a parent to arrive with food. The bird would stretch his wings and put them out a bit to help with balance but otherwise didn’t move except when a parent came within earshot. Then he began fluttering his wings and calling with an open mouth guaranteed to trigger the instinct to stuff something down it.

   

Sometimes, this meant having to turn his head 180° to get it in the right position for the deposit of an insect. This had the desired results.

The bird was alone on the wire for perhaps 20 minutes or so – and then was joined by a couple others. They looked a bit bigger and more developed but I finally realized that these were the bird’s siblings, who had been doing more to practice their flight capabilities.

  

“Wire” bird maneuvered his way down the wire in stages to end up right next to, and then almost on top of, one sibling. He almost seemed to be pecking the bird. This did not go down well and finally brother/sister left after wire bird moved back and forth.

 

The parents arrived sporadically with food, perhaps hoping that wire bird would finally take off – and then he finally did, showing he was not injured at all. I think he simply wanted to have table service and figured staying on the wire with an open mouth was easier than having to try catching lunch on the wing like his siblings.

   

Two siblings finally decided to perch on the wire, too, all making sure to keep some distance between themselves. Perhaps they were tuckered out after all those flights; one took a few naps between visits from mom and dad.

Wire bird was very good at attracting his parents’ attention so the other two tried to become more vocal and began fluttering their wings more as well. They also moved closer to him, likely hoping to intercept a meal.

  

 

Things became a bit more difficult for the parents, who could scarcely alight on the wire before having the food snatched away!

 

 

 

  

Then, one of the siblings seemed to have had enough of wire bird’s success and approached him – to wire bird’s dismay.

They had a little spat!

 

  

  

Sibling No. 2 also took a turn at wire bird – they seemed to be saying that enough was enough and he had to stop monopolizing mom and dad’s attention, care and feeding.

   

  

When a crow arrived, everybody flew off in a panic but it wasn’t long before wire bird was back in place. Mom and dad began arriving much more regularly and the siblings decided being on the wire would be more productive than trying to find their own food. The parents finally began feeding the siblings more and everyone seemed to be pleased with that arrangement.

Towards the end of my 80-minute observation stint, I reflected on how patience showed me much more of what was happening than I had first assumed. If I had left after 20 minutes, I might have gone away feeling sorry for wire bird, thinking he couldn’t fly well and had to rely on his faithful parents. It was only by staying and watching that I saw the nest mates have their spats and I had a new narrative to explain the behavior I was seeing.

 

It would be so interesting to be a researcher who follows the development of a species, avian or otherwise. When I was younger, I probably didn’t have the amount of patience needed to spend more than an hour in position to see what would happen next. Now it was a sore arm from holding up my heavy camera and zoom lens that ended my session. But I’m grateful that I have the time and calm now to watch and wait and wonder about what will happen next. And other than the camera equipment and gas expenses, it’s an inexpensive way to keep learning and enjoying the fabulous natural areas that still remain.
