Neat article about a book on avian zoology:
"A manx shearwater, for instance, was once kidnapped from a burrow on the Welsh coast and flown 3,200 miles (5,150km) before being released in Boston harbour. In less than 13 days it had found its way home. Mr Strycker also alights on the amazing #biometrics
of hummingbirds, whose pea-sized hearts are the largest of any bird when measured in proportion to the bird’s body mass. These vast organs can pound away at a staggering rate of 1,200 beats a minute... but still about 1 billion beats in a lifetime, the same a people." family man, pictured.
