Cuban biologists check snares in a botanical garden in the suburbs of Havana. This time we caught a migrant bird that had flown in from afar. Now she is awaiting a full examination.
Scientists measure and weigh the captive, assess her appearance, and determine the amount of body fat. The data is recorded.
Biologists observe migratory birds. Birds migrate from the USA and Canada.
Cuban scientists are collaborating with researchers from Canada. As part of the Motus program, they installed the first radio telemetry antenna on the island. With its help, you can observe birds on which transmitters are attached.
The transmitters weigh between 0.2 and 2.6 grams, so they can be attached to the smallest birds and even butterflies and bees. The devices last for a while and then fall off. The antenna “sees” transmitters when they are within a radius of 20 kilometers or less.
Recently, using this equipment, an American Swainson’s thrush was discovered in Cuba. The transmitter was put on him in British Columbia in Canada. The bird flew 5,000 kilometers with him.
