After breakfast Doran and I walked down to the beach. To get there we had to pass by the small group of mango trees, cross an open lawn, and descend a few Palm-shaded stairs before emerging onto the sand. There was a wide swath of sand exposed by the low tide, and a large crust of rocks protruding from the water that reminded me that the geological history of Central America is very different from that of eastern North America. The land bridge connecting North and South America – which includes Costa Rica and Panama – didn’t exist until about three million years ago. Costa Rica was formed when the movement of the western edge of the Caribbean plate forced the Cocos plate beneath what is now the Pacific Ocean to slide beneath it, creating a subduction zone which birthed a number of volcanoes. The relentless grinding of the Caribbean plate over the Cocos plate and the numerous volcanic eruptions over the millennia caused the land mass to grow, resulting in a today’s mountainous west coast with its steep cliffs overlooking rocky tidal lagoons.
Costa Rica operates on Central Standard Time. Being so close to the equator, however, it receives roughly 12 hours of daylight throughout the year; as such, it has no need for Daylight Saving Time, and doesn’t reset its clocks twice a year. This is quite unlike Ottawa, which fluctuates from about 8 hours of daylight at the December solstice to just under 16 hours at the June solstice. It was light enough to go birding around 5:30 am, and started getting dark around 6:30 pm. Costa Rica was two hours behind Ottawa time during our trip, and as a result of the time change, we were up earlier than usual. This made time seem to slow down, for the days seemed much longer, with plenty of hours to fill.
With my sleep issues I still woke up at my usual time each day, which meant I was wide awake by 3:30 or 4:00 am and couldn’t fall back asleep. As soon as it got light I went birding, sneaking out around 5:30 or 6:00 am almost every day we didn’t have any activities planned. We spent our first full day in Costa Rica on the resort, and almost right away I discovered a great birding spot right near our building. Continue reading →
Doran and I arrived in Costa Rica at 12:30pm on Saturday. We’d been planning this trip since February, and it was a thrill when we finally landed in Costa Rica after a 4:00am start that took us first to Toronto, then to Liberia after a five-hour flight down through Florida and across the Caribbean Sea. When we left Ottawa it had been cool and rainy, but the moment we stepped outside of the airport we were engulfed by the heat and humidity of the tropics. Although the humidity of the 30°C days seemed unbearable at first, we grew used to it by the end of the week – although any sort of exertion (such as hiking up the slopes of the volcanoes in the rainforest) was uncomfortably sticky. Still, we were thankful for the air-conditioning of the van that drove us to our resort, the Occidental Papagayo located on the Gulf of Papagayo in Guanacaste, about a 25-minute drive from the airport.
After two gray, rainy, miserable weekends, the sun finally came out on the Saturday of the long weekend. We’d been spoiled with hot, summery weather on Wednesday and Thursday when the temperatures reached the high 20s; however, Saturday morning was cold with persistent north winds that just don’t seem to want to leave. I headed out early to Jack Pine Trail, hoping to photograph the towhees again and also to find some returning residents, such as Virginia Rail, Alder Flycatcher, Eastern Wood-pewee, and Ovenbird. If it had been warmer, I would have also looked for butterflies and dragonflies.
One of the first birds I heard as I entered the woods was the Red-eyed Vireo. As the trees are now leafing out, I wasn’t able to spot this small, greenish canopy dweller whose monotonous song rings throughout parks and woodlands throughout the summer months. This was a year bird for me, though it’s the latest I’ve had one since I started keeping track with eBird.
On May 16th I headed over to Hurdman at lunch to search for some migrants. I only found 17 species in the hour I was there, and all but three were migrants. The first migrant was a Swamp Sparrow singing in the vegetation of a tiny, wet reedy patch that bore little resemblance to the cattail marshes in which they normally breed. The second was a Rose-breasted Grosbeak heard, but not seen, and while it is possible that they may breed here I have never come across any outside of migration. The third was a Black-and-white Warbler.
On May 14, 2017 I received two interesting visitors to my yard. The first was a Nashville Warbler flitting around in the tree outside my computer room – I only got a brief glimpse of the yellow bird with the gray head and white eye-ring before it disappeared, but it was enough to add it to my yard list as bird species no. 66. The second visitor wasn’t a bird, but a mammal; when I saw the small red squirrel poking around the feeder area, I immediately ran for my camera as this was only the second red squirrel I’ve seen in my yard. Although I’m not too far from Stony Swamp where numerous red squirrels make their home, I am just deep enough inside the Emerald Meadows subdivision with its maze of roads and large, open lawns to make travelling a hazard, especially given how open the subdivision is – there are no tree-lined streets and no canopy of interlacing branches for the squirrels to travel along safely above the ground.
Last fall we had the American Pipits, Lesser Black-backed Gull, and all kinds of shorebirds; with so many wonderful birds stopping over at the Eagleson storm water ponds during last fall’s migration, I couldn’t see how spring migration could begin to match it. However, on Sunday I broke 40 species there for the first time ever with a total of 42 – just surpassing my high total of 38 species on September 18, 2016. Even though the shorebird species were limited to the two common summer residents – Spotted Sandpiper and Killdeer – the diversity of the other birds was more than impressive.
Once again I was without a car, so I walked over at about 9:30 through a light rain, bringing my umbrella with me. As soon as I got close to the water I heard the grating calls of a couple of terns and headed out onto the peninsula to take a look. Continue reading →
