Big Day 2018 at Costa Rica’s Carara National Park, And Nearby At Los Suenos Marriott

The first lucky bird of the day, a Yellow-crowned Night-Heron at Marriott, which I hadn’t seen yet on property

Almost four years ago, James and I took a day trip to Carara National Park, on the Pacific coast of Costa Rica where the tropical dry forest meets the moist rain forest in a transition zone that provides a great mix of habitats for all sorts of birds and other wildlife. On eBird, Carara’s Hotspot has over four hundred species, which made it a natural place for me to spend part of my Global Big Day this year, since I was already documenting the avian life on the property of the Los Suenos Marriott in Herradura, just half an hour south along the coast. These photos are from my May 5th efforts!

The Turquoise-browed Motmot is a regular at Marriott and one of my favorite “common” birds in the country

I started the morning at 5:30am, heading out onto the perimeters of the forests surrounding Los Suenos Marriott and its golf course. Continue reading

The Luck of the Draw

We’ve discussed eBird countless times here in the past, but I don’t think I ever mentioned their monthly challenges, which are designed to encourage eBirders to contribute some extra element of data to their usual checklists in a given month, with the chance of being randomly selected from the pool of people who satisfy the challenge requirements. If you’re chosen, you’ll receive an excellent pair of binoculars from Zeiss Optics!

In the past there have been challenges related to adding breeding codes to checklists (for example, noting if a species was observed carrying nesting material, or displaying, or feeding a juvenile); noting flyover species; going out birding with someone else and sharing the checklist; using the eBird app; and more! I think I remember a challenge from 2015 that involved checklists including raptors and vultures, and I recall being frustrated because it came a month after I’d been in Jamaica reporting Turkey Vultures several times a day.

A Step Up for Bird Migration Maps

In 2016 I wrote a couple times about eBird’s data––the observations contributed by citizen scientists––being used for migration maps, among other things. Those posts included animated gif images that illustrated the flow of thousands of birds across the Western Hemisphere at different times of year, which could be used in a casual setting to predict when to go out looking for a target species one wants to see in the wild, or in a conservation setting to know what time of the year is best to enforce certain environmental regulations, like open hunting or hiking seasons in sensitive areas. The moving maps also served as a mesmerizing graphic to simply astound us with the magnitude of travel these birds are undertaking.
