On Catching Up (and Looking Back)

Tweet

Sometimes I feel like the osprey in this photo--not the one with the fish, but the one chasing ineffectually.  I'm not flying as gracefully as this bird, of course, but I'm trying to catch up. The last time I posted was the day before St. Valentine's Day and here it is St. Patrick's Day!  This post won't have a real theme--it'll just be catch-up time.

When I started blogging at the beginning of 2010, my objective was to write something that would help me keep track of a year in the life of the yard.  I had already tried that with various journals and lists, but found they were too easy to misplace--and you can't keep track of details if the list you keep them on is lost.    Even though I don't post as often as I had intended, my blog is always "there" (somewhere in cyberspace) and  I'm finding it really fun to look  back over last year's posts.  Today, as I read over last year's posts for February and March, I was reminded of some interesting observations and found myself comparing them to this year's.

For example, a couple of weeks ago, I took a photo of pelicans  fishing out back in the Arroyo. One of them was the red-pouched form of the Brown Pelican, a subspecies usually found in California.  As I browsed the blog's posts from  a year ago,  I  saw that I was speculating then about how many of our Texas pelicans are this form,  but I couldn't find an answer anywhere.  Trying to figure it out for myself, I counted pelicans as we took a boat trip up the river.  Today I read in the TOS Handbook of Texas Birds (a book I didn't have last year) that about 10-15 percent have the red gular pouch.  I think that's an overestimation as far as the birds here on the South Texas coast--or at least in the Arroyo--are concerned.  Last year's effort to count pelicans and note the ones with the red rather than the grayish pouch made me conclude that more like 2% were the California subspecies. 

Another  thing I noticed after looking at last year's posts (see the links here and here) is that there are not nearly as many Brown Pelicans on the river as there were a year ago.  I hope that has nothing to do with the oil spill in the gulf.  The TOS handbook says Brown Pelicans are not known to breed along the lower Texas Coast.  I think they actually do breed on some of the spoil banks in the Laguna Madre.  If it's not windy tomorrow maybe we can retrace the boat trip we took looking for and counting pelicans last March.  It isn't scientific, but  it is interesting to compare one year's observations with another, and thanks to my Arroyo Colorado Riverblog, it's easy to do that.

Continuing with my catch-up post:  I'm on the lookout for our migrant Hooded Orioles.  Checking the blog for the date of last year's first appearance, I see it's March 18--that's tomorrow.  I can't wait!  The bottlebrush tree is starting to bloom, ready for the nectar-loving birds.  Today three Altamira Orioles flew across the yard and into the tree. For a second I thought maybe the Hoodeds were back.  By non-scientific observation, I know that the same birds migrate back to our yard year-after-year: we once had a male Hooded Oriole with a deformed beak, easy to recognize as it returned for at least three summers.  (I was especially glad to see it each spring, as I feared the deformity would make survival difficult-- but apparently it didn't, or at least not for those three years.)  

A Fuertes's Oriole ( formerly Ochre Oriole) also returned to the yard two summers.  I'm sure it was the same bird since it had  been seen in the United States only once before (late 1800s)--and what are the chances two different Fuertes Orioles would show up in the same yard two years in a row?    Every spring I look for the beautiful Ochre Oriole, but it did not return for a third year and hasn't been seen north of the Mexican border since.  This year, though, I have something almost as good--a lovely watercolor by bird artist F.P. (Tony) Bennett, who  saw it in our yard and has painted it for us. We just got the watercolor back from the framer's today.  Tony's depiction does the bird justice--a really beautiful creature. (To see some of Tony's other paintings, see this link: http://www.fpbennett.com/ )

Speaking of orioles, I'm  looking forward to the Altamira Oriole's yearly magnificent feat of nest-building. Looking back over the blog, I see  it was mid April of last year that they built their first nest.  Unfortunately, they abandoned that one in our Oak tree and built another in a Tepeguahee tree three doors to the west of us.  That nesting was apparently successful--two first-year Altamiras joined two adults all winter in the yard, eating oranges, sipping hummingbird nectar, feeding on aloe blooms, and even eating seeds from the feeders.  Above is one of the young birds.  Note the pale back and tail, and contrast it with the black of the adult below.  Male and female look similar in this species of oriole, unlike the Hooded Orioles whose female is much like the female Ochre Oriole in Tony's watercolor.  

Since I'm trying to catch up with a whole month of yard activities, I've got lots more to show and tell. I also want to tell about a couple of really neat experiences I had away from the yard.  But for now I'll close this post and continue writing tomorrow.  I want to get up early in the morning for some backyard birding.

Will the Hooded Orioles show up tomorrow?  I'll be watching.  

All Things Great and Small

The tragedy unfolding in the Gulf of Mexico, where oil is choking wildlife and killing bays and estuaries, sickens me and makes me angry.   I keep thinking  of Coleridge's albatross (in "The Rime of the Ancient Mariner") that was so wantonly destroyed by the unthinking mariner. When the mariner destroyed the innocent bird of the poem, the seas turned into a nightmare and it's that image I envision in the scene of oil and fire at the site of the fallen rig:

"About, about, in reel and rout
The death-fires danced at night;
The water, like a witch's oils,
Burnt green, and blue, and white."

Yesterday I posted a photo of a Great Egret we saw on its nest at dawn in the Everglades this spring.  In honor of the birds of the Gulf  Coast from here in South Texas (where thankfully we are not affected by the spill) to Florida I'll post some of the other pictures I took on that trip.

Here is the most fascinating bird of our trip: a Wurdemann's Heron, which is a hybrid of the white color morph ("Great White Heron") of a Great Blue Heron and a regular Great Blue Heron.

Can you see the Great Egret sitting on the nest just behind this nest?  If not, click to enlarge the photo.  It's like one of those "how many birds can you find?" drawings.  


The "Wurdemann's Heron" looks like a Great Blue but has a white head.  On our way to fish for tarpon the fishing guide took us by a mangrove island rookery where he knew a Wurdemann's Heron was building its nest.  We approached slowly, using only a trolling motor, and did not disturb any of the birds.  Of course these photos are taken with a zoom lens so we were not as close as it looks.

 In breeding plumage, all the birds were at their most beautiful, especially this Tri-colored Heron I photographed  when we were kayaking in the Everglade's "River of Grass."  I'm used to seeing these guys fly by in twos and threes along our Texas coastal river, but this one was so close I could admire its two-toned blue beak. 

This is the same Great Egret as the one in the photo of my last post.   Its plumes are not showing as well, but the green at the base of the bill is amazing. The color changes during spring breeding season are among nature's most beautiful miracles.

The red bill of the White Ibis is another amazing coloration.

The few American White Pelicans we saw were probably not breeding.  They for some reason had not migrated as the Florida white pelicans do.  We have a flock of white pelicans in our area in South Texas that remain for the summer also.  I see them in the bays sometimes when we are fishing.  I read last week a post on Texbirds that described one being hit by one of those large wind turbines that are along the coast north of us.   The fishing guide in Florida thought these two guys were probably too weak to have migrated.  I wonder if they will survive the summer.

It's the pictures of the Brown Pelicans covered with oil that are so heartbreaking in the news of the gulf oil spill.  As we saw this beautiful bird in breeding plumage on the mangrove islands of the everglades, we already knew that oil was spilling into the gulf and we were hoping that somehow the birds in Louisiana could be safe. 

Another bird we enjoyed seeing in Florida was the Osprey.  This one was nesting on an electrical pole near Chokoloskee Island.

Birds were not the only creatures we saw in the bays and rivers of South Florida.  Here a Kemp's Ridley Sea Turtle comes up for a breath and a peek at our boat.

Seeing a hooked tarpon jump was exciting, especially to my husband the fisherman. Click to enlarge this photo to see the fish  in more detail.

 

Our vacation to see the Florida Everglades, to fish among the islands and paddle through mangrove tunnels
and along the quiet and beautiful "river of grass,"  was a wonderful week of stunning landscapes and fascinating wildlife.  I cannot imagine oil covering and killing this beauty, but of course that is exactly what is happening in other parts of the Gulf of Mexico and it is because of the carelessness, and yes the greed, of humans.

I keep thinking of Coleridge's ancient mariner.  His story is of a man who took for granted the wonder of nature.  As he tells the story, the mariner finally learned a lesson:

"He prayeth best, who loveth best; 

All things great and small; 

For the dear God who loveth us;

He made and loveth all."

It was his punishment to wander from land to land telling the story of the death of a beautiful and innocent bird at the hands of a man who was not evil but who was thoughtless and unaware of his actions.  Coleridge tells us that the "wedding guest," to whom he recounted the story, woke up "sadder and wiser," but I wonder if he really did.  I wonder how many environmental disasters it will take for us to be any wiser.

An Obsession of Pelicans

Tweet

It is almost impossible to look toward the river these days and not see a pelican.  Brown Pelicans fish along the river all day long, sometimes flying so low that their primary wing feathers barely clear the water, and sometimes rising high into the air and then plunging into the water beak-first, twisting as they dive and popping up facing the opposite direction. In a previous post, I noted that a group of pelicans is called a squadron, a pod, a scoop, or a pouch.  Sometimes I think that the collective noun for my pelicans should be obsession, for that is what they seem to have become for me!)

The pelican in the photograph above floated for awhile after its dive, spinning on top of the unusually still water that reflected a nearly perfect inverted image.  About five minutes later,  two other pelicans flew by at medium height, in their flap-flap-flap-glide, flap-flap-flap glide rhythm, and the bird joined them.

I wrote about the pouches of these ponderous birds a couple of weeks ago when I began looking specifically at the colors of the adult pelicans in their breeding plumage.  The feathers of their heads have turned golden on top and  dark brown on the back of the neck.  I'm still looking carefully at the pouch color of every Brown Pelican I see, trying to determine how many of them have the red pouches usually attributed to the California subspecies. (The pouches of the  Atlantic subspecies that you would assume birds here on the Texas coast to be is usually a brown or dark olive color.)  I see one such bird with the red gular pouch at least once a day -- but only one bird a time--which really doesn't tell me how many there actually are. The pelican in the photo above, taken from our dock, has the red pouch I'm talking about, opened wide just after the bird has scooped up a mullet. Stretched like this, the pouch is not quite as dark red at it appears when the bird is at rest, but you can nonetheless see that it is redder than the pouches of most of our Texas Brown Pelicans.


Last Friday we took the boat out, heading a few miles downriver toward the Laguna Madre, the "Mother Lagoon" between the south Texas coast and South Padre Island.  I counted Brown Pelicans as we went along, losing count a couple of times but seeing at least fifty.  Only one of the birds we saw was red-pouched.

That's it in the back of the picture below, behind the one that has its head straight up, stretching its beak and pouch. I read that they do this stretching exercise to keep their pouches supple for scooping up meals.

 

These guys, lined up on a neighbor's dock,  must be tired from making so many of those twisting, turning plunge-dives. 

 

I've noticed an apparent  range of sizes in Brown Pelicans.  Notice how much larger the one on the right seems to be than the other three. 

 

This one reminds me of one of those old fashioned decorative doorstops---you would pick it up by the beak and prop it in front of the outside door to keep the wind from slamming it shut. 

Not only have the Brown Pelicans gone through their seasonal changes in appearance, but so too have the American White Pelicans.  In late winter they grow strange fibrous bumps or keels on their upper beaks.  The color of the beaks change from yellow to pale pink and then bright orange. This white pelican floated placidly in the river not long after the the departure of the brown one pictured at the top of this post.  Notice the river water is rippled now.  It seldom stays as glassy still as it was early that morning.

On our boat trip downriver (we never made it as far as the bay) we scouted out not only pelicans, but other wading birds as well.  A Long-billed Curlew waded in the shallow water along the edge (above).

A small group of  White Ibises caught crabs in a small inlet.   (The collective noun for a group of ibises is a congregation or stand or wedge.  I'll say that we saw a stand of ibisis.  These guys were standing but also hopping and shuffling and probing in the shallow water for small wiggly crabs like the one grasped in the beak of the ibis in this photo. Click to enlarge if you can't see the crab.You can tell it has just been caught because the churned up bubbles are still on the surface of the water. )

The Arroyo Colorado,  once an ancient tributary of the Rio Grande River, is now surrounded by agricultural fields. Below the Port of Harlingen it has  been  dredged and widened  for use  as a shipping channel off the Intracoastal Waterway.   But small inlets and "old Arroyo" loops remain, wonderful places to ease a shallow-water boat into or paddle a kayak along.  A narrow border of native scrub along the edge retrieves for a small space a remnant of  habitat that once extended across the valley.

Sitting quietly in a boat in the shallow waters of a little inlet, you can watch a stand of ibises catch small wiggly crabs and pretend the arroyo scrub forest extends for miles and miles beyond the river.

A Pouch of Pelicans

Tweet

When you were a kid, did you learn that poem, "A wonderful bird is the pelican/His bill will hold more than his belican..."?
I can't remember who wrote it (though I do know it wasn't Ogden Nash) or how the rest of it goes, but I do agree that the pelican is a wonderful bird. On days like today I find that silly rhyme running through my head.

I've spent the day watching Brown Pelicans. I love to see them fly over the river, watch for fish, and then dive in the water with a twisting motion, hitting it hard enough to make a loud splash. Sometimes two or three pelicans will be fishing together and dive at almost the same time. As they enter the water, they fold their wings and go in beak-first. The twisting motion must continue underwater, for they always come up facing opposite of the direction they went in. They slam in hard and come up fast. If their dive is successful, they stretch their throats upward and you can often see a fish filling out the pouch before they swallow it. Mullet and menhaden fish are their preferred food (according to what I've read) and we definitely have those in the arroyo. (Menhaden are the silver "shiners" that fishermen net up for bait, and mullet are the silvery fish that jump out of the water, sometimes in a series of three or more leaps. People don't like to eat either menhaden or mullet, but the pelicans certainly do.)

Yesterday the bird in the photo above made a loud splashing dive just out from the dock as I watched from the porch. I wasn't specifically looking for pelicans and at first I paid little attention to it. But something seemed different about this bird. I kept looking at it, first as it ate the fish it caught in its dive and then as it paddled around for awhile. I noted that it was in breeding plumage, a yellow/gold on its head and dark brown on the hindneck, but that wasn't the difference I was sensing. Lots of the pelicans I'd been watching for the last couple of weeks had that.
It wasn't until I looked at the photos I'd taken that I realized what didn't seem right: its gular pouch was not dark brown or gray as most of the Brown Pelicans I see, but a surprising red. I checked several field guides. Most didn't even mention this coloring at all, but the couple that did identified it as a fieldmark of the pacific or California subspecies. This guy might be a long way from home! I don't know how many of "our" pelicans have this coloration--but it is beautiful!

Today I watched for Brown Pelicans all day so that I could get an idea of how many had the red pouch--and I only saw one. It may be the same one I saw yesterday, of course. I saw dozens of the birds flying and floating and diving but only one that looked the same as the photo above. I'll keep watching. Tomorrow we may go out to the bay where there will be many more birds to compare.

One last Pelican note--while reading about them on the internet, I found out that a group of pelicans is called a pod, a pouch, a scoop, or a squadron. I especially like the last two designations. I've seen White Pelicans fish at night on the river, strongly paddling in a v-formation, scooping their beaks back and forth in the water almost in unison, "herding" the fish to the birds in the back. That was definitely a Scoop of Pelicans! Tonight I saw a scoop of 34 pelicans, and at last I got a (rather fuzzy) night photo.

What does this look like to you-- a Pod, a Scoop, or a Squadron of Pelicans?

Catching Up

Tweet

I got off to such a good start for the year--created a blog to record the happenings in the yard, listed yard birds on e-bird--and then all my good intentions (of keeping up with a journal/blog) went by the wayside. But a very nice wayside it was--a new granddaughter! We drove the six hours to our daughter's house and then watched grandchildren instead of birds. Here's our little sweetheart.

Before leaving town, I took a few pictures of the Brown Pelicans that fly along the Arroyo Colorado, diving in when they spot a fish. They especially like to follow the barges and fish in their wakes.

Brown pelicans are certainly not rare here though I know until recently they were a threatened species. Over the years of watching the river we have seen their steady increase and now they are numerous.

Another picture I took just before leaving town for a couple of weeks was of a Kiskadee eating the berries of the shefflera. Remember the papaya tree next to the shefflera with the blooms that the hummingbirds were enjoying so much?

Well, when we returned home, a freeze (first one in several years) had turned the leaves and blossoms into a dark shriveled mess. I don't know if the tree will be lost or not. Most of the yard is not affected. In fact, some plants look better than ever--the lantana, for example.
