The Lesser Big Day

I woke up at 3:00 a.m. to go birding the other weekend. Though I consider myself a beginner, waking up so early made it seem as if I were crossing some invisible line that set me apart from the casual birder. The stated goal was to hit several spots along the Washington coast in search of shorebirds. There were five of us who went. The three beginners included Sugata and me and one other person. Tony DeFalco of Feathers of Color was one of our two experts.   




The first place we stopped was Ocean Shores, Oyhut Wildlife Area. The experts had timed our visit to be within two hours of high tide, and we were on schedule. We passed a structure that emitted a pulsing sound and bore labels warning us that interference could result in loss of life. Something about air traffic control. We ducked through some bushes and followed a narrow path that led us to a muddy flat land.


At first sight, everything looked quiet, but out came the spotting scopes and mud-colored birds quietly picking at the sand came into view. Plovers. Sandpipers. And with the expertise of our experts I added to my knowledge base of shorebirds:


Western and Least Sandpipers flock together. When they land, they tend to separate; the smaller, Least Sandpipers head toward the land, while the larger Western Sandpipers wade into the shallow water.

The other beginner commented that it seemed remarkable that when the sandpipers took off in a flock, they didn't run into each other. This, in turn, sparked a story from one of the experts with the moral that perhaps birds have a harder time predicting the movement of different species of birds.




It can be difficult, I learned even for experts to tell certain shore birds apart. Thus I began to learn the patience required by those that would ferret out the true identity of the species we were observing. While the experts spent ten to twenty minutes trying to determine if the Plovers in our view were American Golden Plovers or Pacific Golden Plovers, we beginners stood around pointing our binoculars at moving objects.  "What's that over there in the mist?" I asked. I'd seen an intriguing large-billed silhouette disappear below a mound that separated us from the ocean proper. It turned out to be a Brown Pelican. Had I known how many Brown Pelicans we would see that day, and how close, and how little we would see of Plovers, I might have attended more to my shore-bird education. 

The experts had resorted to peering hard through the scope to count "primaries," that is, the feathers found at the wingtips of the birds, which, when the wings are folded, and the subject of study is going about its feeding and could care less about you counting anything on its body, can be difficult to do. Identifying the the Black-bellied Plovers proved no trouble for the experts. One showed up in breeding plumage, brandishing its distinctive black belly. I quickly became confident that I, too would be able to tell Black-bellied Plovers from the rest of Ploverdom, but at home the next day as I leafed tbrough my Sibley's guide, I noticed that all Plovers in breeding plumage boast a beautiful black belly. So much for the brief candle of confidence.


A few drops of rain accompanied by a rumble of thunder sent us scurrying back to stand under the pulsating something-to-do-with-air-traffic structure for cover. In a few minutes the rain subsided and we ventured out again. We saw a flock of Wilson's Snipe, Short-billed Dowitchers probing the sand, Pipits, Dunlin, Killdeer, and a Semi-pulmated Plover which looks very similar to Kildeer but has only one band on its neck instead of two. The Kildeer has more rufous coloring on its back. It also has that distinctive call, the one where it supposedly cries its own name. But the calls we heard it utter were only one syllable and there was some disagreement among the group about whether the poor bird was crying "kill" or "deer." 


The Pipit is named onomatopoeically as well, and its flight undulates much like its call. Up and down, up and down as if hopping over invisible hills of air.

We saw Lesser and Greater yellow legs. A slightly larger size identifying the Greater, along with a slight curve of beak. The experts  seemed to concur that the Lessers tend to be more active, and stride about more vigorously on their long, (yes, and surprisingly bright) yellow legs.



Sugata and I took notes on paper, but we lost track of precisely how many sights we visited and which birds we had seen. But Tony was well-prepared and subtle in his record-keeping. I saw him look occasionally at his phone and assumed he was sending or receiving texts. What he was really doing was noting down each location and each species in a special app. His records indicate that we visited at least nine different locations in our quest for birds. 

The other expert had an especially keen ear for birds. Before the three of us in the back seat could entirely extract ourselves from the Toyota Rav 4, he would be pointing skyward or to a tree, incanting, "Hairy woodpecker," or "Orange-crowned warbler." 

We were not, of course, restricting ourselves to shorebirds. The smallest Savannah Sparrow feeding among the red sedge was worthy of our list, as were the song sparrow, the starling, the gull.  Sugata cried out with delight every time he saw a pelican, though we saw many. The other members of the party who had already turned their optics toward scarcer and more exotic birds, may have been amused, but for Sugata, Pelicans always proved magnificent subjects for photography.



We'd seen plenty of the Double-crested Cormorants near the Willamette in Portland, but on the coast we saw the Pelagic cormorants which are all black, and a little sleeker looking. Sugata noticed that one of the cormorants was sitting with its wings spread out and asked what the bird was doing. "Drying its wings," the experts told us. Cormorants are ancient birds, and unlike many younger waterbird species, never developed water-repellent feathers.  





Once while birding in an isolated location, the other beginner spotted  someone in the distance and asked jokingly whether the "White-capped human" was male or female. "Male," was the immediate answer. Tony claimed that the hobby tended to be male-dominated. Which led us to a discussion of gender bias in bird-watching. He suggested that one of the reasons for the gender bias was that women generally weren't as comfortable being out alone as men were. The other expert, who teaches classes at the Audubon society, claimed that 95% of the students in his classes were women. Thus it became unclear as to the true ratio of male to female birdwatchers as the female may be well-inclined to learn about birds, but less inclined to bird alone.

Individually, Sugata and I recognized, growing in the sand, the sea beans we often buy at the farmer’s market.




We walked out on piers and jetties for chances of seeing birds that prefer the open ocean to land. One expert pointed out a line of dark shadows skimming just above the surface of the sea.  I could barely make them out. He identified the shadows as Sooty Shearwaters, and they were travelling northward in a steady but somewhat sparse stream that seemed to break into clumps of about half a dozen at a time. 

I was initially unimpressed with the Sooty Shearwaters, those nearly invisible wisps in the mist, though one expert piqued my curiosity by mentioning that they breed in Australia or thereabouts.  He scanned the sea with his binoculars hoping to find among the Sooties, a glimpse of a Manx Shearwater, a "life bird" for him. He told us that once on a Pelagic trip, he'd seen 100,000 Sooty Shearwaters migrating. Pelagic trips tend to truly separate serious birders from casual birders. Pelagic trips involve going at least 25 miles out to sea on a small boat, getting immensely seasick and seeing birds that you wouldn't otherwise see on shore. Shearwaters are among these. Tony told us of his Pelagic trip. He was sick the whole time he told us, but had a great time. A true and valiant birder.


On our way to our final destination, the Tokeland Marina, we noticed a heavier stream of Sooty Shearwaters and pulled into turnout for a better look. I spied down the line, what appeared to be a sort of bird rave with gulls, Sooties, and Pelicans. There were birds circling and diving and sitting on the water. "What's happening over there?" I asked pointing. The experts said it must be a “bait ball,” a huge school of small fish, ready for the taking. I know of few species that can resist delicious free food. The bait ball made its way back toward us, until the air and the sea in front of us was swarming with birds. The expert told us that what we were seeing, right there on the coast was what we'd normally see on a Pelagic trip. 
We stood agog for several minutes, our faces toward the sea. One local pulled into our turnout, and getting out of his truck remarked. "I've never seen anything like this," he says. "I live here and I've never seen anything like this before."  The expert first estimated the number of Shearwaters as somewhere near 100,000, but changed his number as we traveled farther down the road kept seeing the birds flock in. The final estimate entered was 250,000.

Many other species of birds were a significant part of this trip. I'd like to thank the Marbled Godwits, the Elegant Terns, The Heermann's Gulls, The Belted Kingfisher, and the Bald Eagle. Each of you helped make this trip memorable. A special thanks also to the two experts without whom, I might have seen less than half of the species that I did, and certainly wouldn't have identified most. I hardly have time to thank all my "sponsors" (i.e. bird species) as there are seventy-one of you in all, but to each, I want to extend a personal thank you for all you contributed to this Lesser Big Day.










Why a Lesser Big Day? Despite the fact that I arose at 3:00 a.m. and returned home at 10:30 p.m., we were informed by the experts that on a true "Big day" we would have gotten up earlier and gone on to look for owls.

Abode of the Acorn Woodpecker: to be chopped down as usual


One or All of these magnificent 200 year old trees(? do not know exact age- they could be older!) will be chopped down: soon. I have seen blue jays and acorn woodpeckers frequent this stand of trees.
At the Orenco station for the inter city train line in Hillsboro, Oregon, USA is a stand of old magnificent Oregon White Oaks. Till recently I did not know anything about these trees. I would get off at the station, and be off to work. As a transplant from across the world, the trees did not mean  much to me- they looked like other trees and I did not know that it was an oak tree.

About a couple of months ago, I got off the train as usual, and noticed that there was a woman at the station who was asking people to sign a petition. I was almost about to walk by, when I overheard what she said to someone else, "Saving the oaks over here".

I talked to her and found out that she was asking people to sign a petition to show the city of Hillsboro that there were people who cared about the oaks; Oregon White Oaks that were slow growing trees; trees that were at least 200 years old; trees vital to the ecosystem which provide food and shelter to a myriad range of species- the magical interconnected web of nature. I signed the petition to voice my support.

On the same day, when I was coming back from work, I saw the same woman standing in the blazing hot summer sun asking people to sign the petition. I felt sorry for her, and admired her love for the trees.

Panoramic view of the property where houses will be built: looking west from the sidewalk on the edge of the property. The property is currently owned by Trimet.
A bit of googling led me to find out about the trees and the region. OreNCo stands for Oregon Nursery Company, which used to operate in this region in the late 19th and early 20th centuries. The MAX train line property was initially part of the Oregon Electric Railroad, which was planning to build a branch train line from Portland to Hillsboro via Beaverton. Trimet currently owns the "Right of Way" - on which the current train line and property stands.
There is a developer who wants to build a $120 million housing complex in this area, and the initial plan was to chop down the trees: because the trees would get stressed during the construction, and eventually die. The latest news is that the city recommends chopping down one of the three large trees: (here is the link to the article in a local newspaper with the story:
http://www.oregonlive.com/hillsboro/index.ssf/2013/07/platform_district_2_white_oaks.html)

Curiously, the newspaper article mentions the citizens petition which I had signed, (along with around 140 other people). I could not find the citizens group online through my initial googling.

According to some people a tree needs water in its dripline area to survive. The dripline is the area under the tree from which water can be partaken. Recently, some scientists think that the dripline for a tree may extend as far as twice the distance from the base of the tree to outermost extent of the foliage. Here is an article containing the questions posed by the citizens, and some of the controversy regarding how the health of the tree is assessed. :http://www.oregonlive.com/hillsboro/index.ssf/2013/06/holland_hillsboro_arborists_me.html

Of Seeds and Birds

Recently, I went on a birding trip to a nearby area in Hillsboro, called Dawson Creek by the Hillsboro Public Library. I was with an excellent group of birders, and among the many birds we observed was the Acorn Woodpecker. It was my first time seeing this bird in action. I had seen glimpses of it in the past, but here I saw all the drama of a bird trying to drill a hole in its tree; the cache location being observed by other birds, the bird flying to another tree nearby and resting and observing other birds caching the seeds. After observing them for over half an hour, a bird landed close to me, and I was able to get some good pictures of this bird.


Holes drilled into trees to cache acorns by the Acorn Woodpecker.

The acorns (seed of an Oak tree) contains bitter tannin. The tannin is thought to prevent the absorption of protein into the body, and thus this nut does not contain easily absorb-able nutrients, and prevents a bird from putting on much bio-mass. The native people of this area used to soak the acorns in water to leach out the bitter tannin, and make a flour out of the dried nuts.

The Oregon White Oak is a slow growing tree whose seeds form a vital part of the diet for many birds in the area. It is facing habitat loss in much of the areas around the Portland metro area. According to the Metro.gov website, only about 1% of the original 500,000 acres of the original oak savannah habitat remains in the WillametteValley, (most of it lost to agriculture). In many parks like the Mount Talbert park in Clackamas county, fast growing fir trees are "girdled" to kill them; this allows the slow growing Oregon White Oak to survive.

Canoeing the Tualatin River


Sonya and I went canoeing in the Tualatin river yesterday. We rented our canoes from the non-profit group: http://www.tualatinriverkeepers.org/ at Cook Park near Tigard, a town south of Portland, Oregon. We joined as members, and rented a canoe for 4 hours- all for $35.00. The friendly staff supplied us with life-jackets helped us launch our canoe around 11:30AM. One need not be a member to rent a canoe from them- but becoming a member helps you get a discount on future rentals, support this non-profit organization, and find out more about the river from the newsletters we will be receiving.

As is the story of many rivers in the 19th and 20th centuries, this river had become quite polluted due to human activity in the area. However, these days the river is in a much better condition due to the efforts of many organizations like the Tualatin Riverkeepers and The Tualatin River Watershed Council (TRWC), a local watershed stewardship organization. A full history would be a book length study!


The river contains washed off silt from nearby areas, silt which is so fine that if one were to let a jar of water from the river sit on a table, it would take more than 6 months to settle. The river was calm with a gentle current- which meant that paddling upstream was not too tiring. There is a map at the launch site which contains information on sections of the river which are safe and sections which can be dangerous due to dams and possible log jams. We were only planning to canoe 2 or 3 miles upstream and return-and did not have any serious hazards on the way.


"Oooh! Its like glass here"- comment by a fellow kayaker. 


We were lucky to see some new animals and birds today. 

- River Otter?: a dark brown snake like hairy body along the river's edge caught my eye, and its undulating shape slithered beneath the bushes and disappeared from view.

- Spotted Sandpiper?: Grey top- white underneath: this bird (there were two on them on a small grass meadow by the river, one flew away, another landed on a log on the river), dipped its head and tail alternately in a weird dance move.

- Pileated Woodpecker: Its flight made me think it was a northern flicker, but when I trained my binoculars on it, I noticed a red patch on the head, white in between and a black body on a dramatically foreshortened bird that flew directly away from me with cries like "pok a pok a pok wok".

- Green Heron: This is the bird that adorns the logo of the Tualatin Riverkeepers. On the way back, I wanted to have a closer look at some violet flowers growing on a rock, and we saw a bird fly into the bushes as we approached the bank. As we were leaving the area, we noticed a bird land on a log-through the binoculars it looked a miniature version of a great blue heron- a foot tall, with yellow eyes, a long yellow beak and yellow feet-with a "S" shaped neck and striped feathers. Juvenile?

Guide to exploring the Tualatin River: "Exploring the Tualatin River Basin" : A Nature and Recreation Guide by Tualatin Riverkeepers.


- Olive-sided flycatcher?: This bird was on a branch on a tree close to the heron, and had a pale yellow chest, and its angular head in profile looked like a miniature kingfisher.

- "Tree Bass": this is what a guy said pointing to his fishing line caught in the tree as he was standing on a boat launch dock.

Some of the regulars were

- Belted Kingfisher: The placid canoe trip began with a loud belted kingfisher emitting loud cries in the bushes, and then darting back and forth in the river ahead of us. We saw the same bird (or possibly another specimen according to Sonya) a few more times on the river and on our way back.

- Red-Tailed Hawk: we saw a few of them circling overhead scanning the area along the river for food, and heard their "kileree" through the tree canopy without being able to locate the bird at other times.

- Scrub Jays
-Starlings
-Norther Flicker: Many of them criss-crossed the river with their familiar flight pattern, flying up and then diving like a custom input to a power electronic device.

- Dragonflies skirting the surface of the water.


- Mallards: flying by, and mallards extending their necks to eat low hanging berries from an unknown plant

It was fun to watch mallards sitting in the water, extend their necks to reach for the berries shown in the photo above


There were many paddlers on the river; some muscular, some not in the best of shape, families with children, couples, singles, people fishing from private docks along the river, all politely saying hi and waving to each other as we passed each other. A woman kayaker put it perfectly with her comment "It is like glass here!" on a quiet section of the river. For the three hours we spent on the river, we were only passed by one motor-boat- that too someone who courteously slowed their pace to a gentle crawl as they passed us.






Food:
- Onion flavored Thanh Son Tofu
- Gluten-free bread with basil cashew pesto made  by Sonya
- sugar plum tomatoes
-organic baby carrots


Public Transit:
- MAX from Goose-hollow to Beaverton Transit Center
- 76: from Beaverton Transit Center to stop near Cook Park: http://goo.gl/maps/YbIae
- Walk from bus stop to Cook Park: http://goo.gl/maps/zfUvq

 I would highly recommend this trip as a relaxing way to connect with nature in a place that can be easily accessed by Public Transport.
