My love affair, take 2

osprey IMG_0689© Maria de Bruyn res

The ospreys (Pandion haliaetus) continue to capture my heart, even though my numerous forays to lakes and ponds to get some excellent photos of them have not yet paid off. I finished the book on osprey migration, Soaring with Fidel, and thoroughly enjoyed it.

Reading about different birds’ personalities and choices for migration was really interesting; learning about the different people who dedicate their lives to learning and sharing information about ospreys kept my interest, too. The ospreys definitely have a devoted fan base.

It’s quite amazing to think of these birds flying several thousand miles within a short period of time so that they can spend the winters in warmer Caribbean and South American climes. When I was at Topsail Island, I was lucky to see a few ospreys that were apparently on their migratory journeys. They flew very far overhead, but I did see one drop down into the ocean and come up with a meal.

One day when I was at North Carolina’s largest man-made lake, Jordan Lake, I was lucky to see an osprey begin a predatory dive that was a bit nearer to me than usual.

The bird’s wings and claws were spread as it readied itself to grasp the fish that was in sight down below.

osprey IMG_0806© Maria de Bruyn resSometimes the birds will face forward to dive down and then flip upwards at the last minute so they enter the water feet first. This bird did most of the dive with its feet down in the clutching position, ready to strike.

A mighty plunge!

osprey IMG_0815© Maria de Bruyn resThis was a happy bird. And when another (or the same?) bird suddenly flew right over my head to grace me with a piercing gaze, I was a happy birder!

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_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.

Tropical kingbird IMG_8081X mdbTropical kingbird IMG_8113Z mdb

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.

Delight in small packages

ruby-throated hummingbird M de Bruyn signed (2) res

Ruby-throated hummingbird IMG_6085©Maria de BruynOne bird that seems to almost universally delight people and bring smiles to their days are the hummingbirds. These wonderful little fliers now only live in the Western hemisphere of our earth, but two 30-million-year-old hummingbird fossils were discovered in Germany so they did live elsewhere.

There are more than 300 species – some very, very colorful and some with gorgeous long tails or long curved beaks. Central and South America have spectacular species and one of the Nazca line drawings in Peru depicts a hummingbird. Only eight species breed in the United States.

Here in Chapel Hill, I’ve had the pleasure to see two species – the ruby-throated hummingbird (Archilochus colubris) and the rufous hummingbird (Selasphorus rufus). The ruby-throated (named for the male’s brilliant neck feathers) are here in spring, summer and fall and then they migrate further south, crossing the 500 miles (800 km) of the Gulf of Mexico in one non-stop flight!

Ruby-throated hummingbird IMG_8991©Maria de Bruyn resRuby-throated hummingbird IMG_4837©Maria de Bruyn

The rufous species migrates here from further up north in the wintertime; they will go as far as Alaska to spend the winter and can tolerate below freezing temperatures.rufous hummingbird IMG_1789 M de Bruynrufous hummingbird IMG_2022 MdB

Ruby-throated hummingbird IMG_7541©Maria de BruynRESThe smallest bird species is the Bee hummingbird, which weighs less than a cent coin. On average, the ruby-throated hummingbird weighs less than a US five-cent coin.

They flap their little wings about 50 times per second but increase this to as much as 200 wing beats per second. This rapid motion makes a humming sound, which varies according to the species. Their quick flight allows them to hover as well as fly backwards and upside down.

ruby-throated hummingbird IMG_3293 MdBTheir little feet help them perch but they cannot hop or walk on them.

These little birds need to eat about half their weight in sugar every day, which is why you see them returning to feeders quite often. When there is not enough food, they can go into a hibernation-like state, slowing their metabolism to 1/15th of its normal rate.

Their hearts can beat as quickly as 1260 beats per minute and they take 250 breaths per minute, even when they are sitting still!

Hummingbirds do not suck up nectar but quickly lap it up with tIMG_5526©Maria de Bruynheir tongues, which have tubes running down their lengths.

To ensure they have enough food, they can sometimes defend their feeding areas vigorously against other hummers that they consider intruders. This happens a lot at my feeders but they are so fast that it’s very difficult to get good shots of it.

They eventually will tolerate others in their vicinity (sometimes). They live 3-12 years and perhaps the ones they don’t mind having around are related.

Ruby-throated hummingbird IMG_2742©Maria de Bruynres

It is better not to put food dyes into nectar and brown or raw sugar should not be used to prepare it as these types of sugar contain iron, which can kill hummingbirds if they get too much over a certain period of time. They like sugar water with 25% sugar, although apparently nectar with 35% sugar is even more to their liking.

I have yet to find a hummingbird nest made with spider silk and lichens in my yard but hope to see one in the future so that I can say I’ve not only seen the biggest bird egg (ostrich) but also the smallest!
