A Walk on the Beach

Hermit Crab

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: Birding around the Resort

Great Kiskadee

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.
