Danger on the beach!

great black-backed gull IMG_4207© Maria de Bruyn resDuring a recent visit to Topsail Island, one of my favorite get-away sites, the various gulls, terns and other birds were very busy: resting, eating and investigating beach debris such as twigs, like this great black-backed gull (Larus marinus).

When I looked through my zoom lens and saw two juveniles of the species picking up and dropping items into the sand, I decided to photograph them. Given some deterioration in my eyesight, even through the zoom lens, I thought one of them was examining a large black twig so I shot away. Imagine my surprise when I downloaded the photos to my computer and enlarged them to see what the gull was actually carrying around!

Most of the time, s/he appeared to be grasping the knife by the blade rather than the handle end, which totally amazed me.

The bird would drop the paring knife and then pick it up again.

One time it was by the handle.

I wish I had realized what the gull was doing when I was there so that I could have picked up the utensil but at the time, I was convinced it was a twig and after shooting the series, I turned to other birds.

I posted the photo on a Facebook birding group page with the remark that: “Beach-goers and fishermen need to pay a lot more attention to what they leave behind onshore!” The responses that came were interesting:

– wow…scary the things people leave behind
– I hope he dropped it when he realized how sharp it was!
– Smelled like fish most likely….
– Sometimes they ‘steal’ from us while our backs are turned on a fishing pier!
– Maybe he’s in a gang?
– Considering it’s Topsail, more likely one of Blackbeard’s crew. Nice image of the gull.

And then one person apparently doubted that the photo I had posted was real: “The size of the gull and the size of the knife looks fishy. The knife is only a bit longer than the beak. That must be one big gull. It’s all in the perspective, I guess.” Since I don’t own Photoshop or some other program with which I can combine photos or insert things into photos, I can assure you that the series shows what happened.

While the respondent who mentioned birds stealing items from people is stating a fact, this site was at the end of the island very far from any piers. So I can only assume that some careless human left the knife behind on the beach (like the cell phone cover and plastic that I collected for the garbage that day).

It is well known that the trash on beaches often ends up in the sea, harming animals that ingest it and contributing to large floating garbage piles.great black-backed gull IMG_4311© Maria de Bruyn resOn 20 September 2014, the Ocean Conservancy is sponsoring the International Coastal Cleanup — the world’s largest volunteer effort to clean up waterways and the ocean. I don’t live near an ocean but will pick up trash near a large lake in my area. And I urge you all to participate in some way if you can! It may be a drop in the ocean/waterways bucket but the drops add up!

I’ve fallen in love!

It would be cool if it was a male of the same species as me, but I have come across another species that is giving me great joy when I see it. Ah, pray tell, say you – what or who has won your heart?

osprey IMG_9944©Maria de Bruyn

osprey IMG_5354©Maria de Bruyn resIt’s this raptor that has seized my attention and grabbed my thoughts so that I return again and again to spots where he (or she) is known to be seen. I haven’t lost my affection for the many other avian family members, but the graceful flight and piercing eyes of the osprey (Pandion haliaetus carolinensis) have captured my imagination for sure.

 

The osprey’s beautiful face with a black stripe highlighting its focused gaze is actually more attractive to me than its bird of prey cousin who delights so many, the bald eagle.

IMG_8405©Maria de BruynOver the past few months, I’ve discovered I’m not the only osprey fan around. During various visits to Jordan Lake, I’ve now met at least 8 guys who devote themselves to photographing raptors. They tend to get more excited when spotting an adult or juvenile eagle, but they will definitely train their zoom lenses in the direction of osprey looking for a meal.

osprey IMG_9503©Maria de BruynThe ospreys circle round and round in the air high above the lake, training their eyes on the water because their superb vision allows them to see the fish underwater.

Sometimes, fish jump out of the water fairly close to me, leaving an ever-widening circle wavelet which is a give-away of their presence. Yet the osprey often ignores those tell-tale signs and looks elsewhere – often at a good distance from where I am so that my shots are mostly from far away and a little blurry. But that gives me motivation to return again and again, hoping for a sharply focused close-up one day!

The bird’s wingspan averages 127–180 cm (50–71 in) and they can weigh up to 2.1 kg (4.6 lb). Interestingly, ospreys are found in all continents except Antarctica, so this family has gotten around!

They are fairly successful hunters. It’s not unlikely to see one beginning a dive, only to halt its descent half-way, apparently deciding that a plunge won’t be rewarding. They begin their dive head first. Then, at the last minute they flip upright so that they enter the water feet first, with claws spread wide and ready to snatch their prey.

Very often when they crash down into the water, closing their nostrils so that they don’t get waterlogged heads, they arise with a fish. Like owls, ospreys have reversible outer toes which help them grab their slippery prey with two toes in front and two behind.

IMG_8401©Maria de Bruyn resIf the fish is large, the bird may have a bit of a struggle to arise from the water while gripping its meal tightly in its talons. Apparently, if the fish is too large, an osprey may not be able to let go and then can drown; luckily, I’ve not witnessed that.

 

osprey IMG_9908©Maria de BruynIt’s not unusual to see them holding their capture in only one foot , however. Sometimes, they will circle for quite a while holding their fish before they head for a tree where they can eat it at their leisure.

Ospreys usually mate for life and they re-use nests from one year to the next. Some nests have been in use for as long as 70 years. These birds often live 7-10 years, but some individuals have been known to survive up to 20-25 and even 30 years.

My fellow raptor photo-graphers and I are not the only osprey fans around. More than 50 international postage stamps have featured this bird of prey and sports teams have been named after them (sometimes using the nickname Seahawk).

osprey IMG_9908©Maria de BruynDavid Gessner, a nature writer based at UNC-Wilmington, has written a couple books about osprey and I was recently lucky enough to get Soaring with Fidel at a bargain price. I’ve just begun reading his adventure in following the ospreys’ migration and expect it will heighten my enjoyment of the photographic pursuit. Knowing these beautiful birds will be soaring overhead when I visit lakes and ponds has certainly made me one of their faithful fans; we’ll be seeing one another for some time to come!

“Regal” members of the bird world

ruby-crowned kinglet IMG_2027©Maria de BruynWe usually don’t know who gave a bird species its common name and sometimes may scratch our heads wondering how and why someone ended up choosing a particular name. But birders faithfully learn to identify birds with those names, even when they may seem illogical. For example, many people would have chosen to call red-bellied woodpeckers red-headed woodpeckers since the reddish belly feathers are much less obvious than the red on the back of their heads.

Sometimes we can guess at why a bird got a certain name, however. The species with some form of “king” in their names were apparently felt to have something regal in their bearing or behavior. These birds don’t look similar though.

Some are quite small, like the ruby-crowned kinglet (Regulus calendula). This tiny bird, which weighs only 5-10 g (0.2-0.4 oz), is a bit dull in color except for the ruby crown that the males occasionally display. They are very active and very cute and having them leave the forest and woody areas to visit your bird feeders is a real treat.

The golden-crowned kinglet (Regulus satrapa) is even smaller, weighing on average 4-7.8 g (0.14-0.28 oz). The males and females both have crowns, although the males can have an orange patch in the middle of their crowns.

The tropical kingbird (Tyrannus melancholicus) is larger and has a crown stripe that is less obvious than the kinglet crowns.

The belted kingfisher is larger still (Megaceryle alcyon) weighing 113-178 g (4-6.3 oz). The females are more brightly colored than the males, showing a reddish band across their breasts (both male and female juveniles have the reddish bands but adult males lose theirs).

Belted kingfisher IMG_5329©Maria de BruynresBelted kingfisher  IMG_9360f© Maria de Bruyn

Some birds don’t have regal names in English but do so in other languages. For example, in Dutch and German, wrens are called kinglets; in North Carolina, we talk about Carolina wrens (Thryothorus ludovicianus).

Carolina wren IMG_7891©Maria de BruynresCarolina wren IMG_8909© Maria de Bruyn

And then we have the large raptor (weighing in at 0.9–2.1 kg (2.0–4.6 lb) whose regal background is expressed in its scientific name, Pandion haliaetus. Pandion was the name of the Greek king of Athens who was grandfather to Theseus, who was transformed into an eagle. Haliaetus comes from the Greek word for sea eagle. We call this regal eagle by the simpler name osprey.

So these kingly birds are all quite different, ranging from the tiny kinglets to the robust osprey. What they do have in common is their loveliness, displayed in diverse size, color and plumage, and our appreciation for their beauty.

Thrushes – speckles and spots, or not

Learning to “bird” (i.e., spot birds and determine what species they are) is no easy matter. There are guides that have color-coded pages so you can begin by looking for birds that are primarily of the color of the one at which you happen to be looking, but then the females and males can differ greatly and the young can look very different from their parents, too.
Hermit thrush IMG_1357©Maria de Bruyn blogIf you can learn something about “families”, that will help you narrow down your search in other guides. So I began associating the family of thrushes with birds that have spotted breasts. I discovered that is true for some of the avian species that have the word thrush in their name, like the hermit thrush (Catharus guttatus) with its reddish tail and the wood thrush (Hylocichla mustelina, below right) with a really beautiful song.

Hermit thrush IMG_1359©Maria de Bruyn blogwood thrush IMG_5416©Maria de Bruyn blog

Wikipedia says that a characteristic of this bird family is that most species are of a gray or brown color, often with speckled under parts. But you can’t count on that being a definitive trait. For example, the large brown thrasher (Toxostoma rufum, below left) is not in the thrush family but its speckles and streaks are more than obvious. And the lovely little ovenbird (Seiurus aurocapilla, below right) with an orange stripe on its head looks similar to the hermit thrush but is actually a member of the warbler family.

brown thrasher IMG_8217©Maria de Bruyn resOvenbird IMG_0044© Maria de Bruyn blog

You can’t count on the name to help out either. The Louisiana waterthrush (Parkesia motacilla) is not a thrush at all but a somewhat larger warbler species that places its nest near water.

Louisiana waterthrush IMG_1260©Maria de Bruyn blog

American robin IMG_3049©Maria de Bruyn resOn the other hand, I was surprised to find out that American robins (Turdus migratorius) are thrushes. But then I saw that the young robins do have speckled breasts – very obvious on this one to the left.

And I learned that Eastern bluebirds (Sialia sialis) are a thrush species, too – those spots are also evident in the young!

 

 

Eastern bluebird IMG_6155©Maria de Bruyn resEastern bluebird IMG_5850©Maria de Bruyn

It turns out that Eurasian (common) blackbirds (Turdus merula) are thrushes, too. The males, like this one seen in Switzerland, are all black but the females show some spotting.

Nevertheless, speckling and spotting are no clear-cut clues to thrushes and common names can be confusing and deceiving. Perhaps I should give up on examining bird breasts to help figure out what species they are. Enjoying the birds, their behavior and their appearance is a much better birding experience for me than aiming to become an identification or birding expert!

Bluebird young’uns – take 2!

Eastern bluebird IMG_1285©Maria de Bruyn resThe first week after they fledged, I didn’t see the baby Eastern bluebirds (Sialia sialis), although their parents were frequent visitors to the suet/meal worm feeders. I hoped that they had made it and not fallen prey to a neighborhood cat or other predator. When I decided to take photos at the time of the summer solstice, however, I discovered they are all doing quite well and keeping mama and papa quite busy!

Eastern bluebird IMG_1248©Maria de Bruyn res

 

 

 

Sometimes they perched nearby and waited for a parent to come to them with a meal. Other times they waited in nearby trees.

They also followed their parents to the feeder, perching on a bamboo stem or feeder pole, waiting and calling to make their hungry desires known.

 

Eastern bluebirds IMG_1123©Maria de Bruyn res

They could be quite demanding, which may account for the parents stuffing their mouths quite full of meal worms.

I guess those wide open mouths make it quite obvious what they are after.

Eastern bluebird IMG_1254©Maria de Bruyn res

I don’t know whether there was some rivalry in play here or one baby misjudging its landing coordinates on the pole very badly. Good thing those claws missed its sibling’s eye!

Eastern bluebird IMG_1696©Maria de Bruyn resEastern bluebird IMG_1696©Maria de Bruyn close-up
Not every juvenile was just expecting waiter service from dad or mom, though. One young’un (“Southern” for young one) began practicing meal worm gleaning from the feeder him (or her)self, successfully I might add.

Eastern bluebird IMG_1275©Maria de Bruyn res

As his or her siblings learn this, it will be nice for their parents, who probably will want to distance themselves from the constant nagging for food. It will be interesting to see if they decide to nurture a second brood this year!
