Just completed a week-long trip to Brazil, focusing on the Atlantic Forest area as well as the central Cerrado region. We spent most of our time (six days/nights) at REGUA (Reserva Ecológica de Guapiaçu) and did quite well there. All together we recorded 253 species and 134 lifers in about eight days of birding. REGUA is a… Continue reading Brazil, April 2019
In 2018 we lived in Thailand, and went birding every weekend and during about five weeks of vacation and holidays. I determined that we boarded about 106 different airplanes in the course of a year, hitting over 20 countries, many of them multiple times. I was looking forward to a relaxed 2019, free from planes… Continue reading Peru, February 2019
Imagine a birding trip that would allow you to record at least one species from every taxonomic order – and that the trip included the least number of sites and required the least amount of time to complete. Clearly, certain countries will have to be in the itinerary (e.g., New Zealand, Madagascar) and the timing… Continue reading Minimal Number of Birding Sites Needed to Record Every Order?
From Dec 26, 2017 through December 25, 2018, I made a quixotic attempt to identify at least 2,500 species over the course of a single year, while working normal full-time hours. I called this a “Global Big Working Year” or GBWY. In the end, I reached 1,770 species, which was just over 70% of the… Continue reading Global Big Working Year
The previous post presented a cartogram for global eBird data by county. Here, we do the same for the States (and Washington D.C.). It is worth noting what the starting conditions are; that is, what base map will be used to generate the cartogram. I am using the WGS84 geographic coordinate system/projection, shown here without any morphing: A… Continue reading eBird Species Cartogram for the United States
Cartograms provide a pleasing way to present geographical data. The idea is to redraw a map so that the relative sizes of its units (e.g. countries, states, counties, etc.) correspond to some measured quantity. A common example is a cartogram of population by country, in which the relative sizes of China and India become exaggerated, while… Continue reading Reshaping the World with eBird Data
We recently took a custom birding tour in Ghana and had a fantastic experience. We worked with Ahanti African Tours and they delivered an outstanding trip. Claire and I have birding together for 24 years, mostly in the US, but abroad starting in 2002. Up to now, South America has been our most productive destination,… Continue reading Birding in Ghana with Ashanti
