lest we forget
Among the 10 species to have become extinct since 1600 (the conventional date for estimating modernextinctions) are two of the most famous extinct species, the dodo and the passenger pigeon.
A flock of the now extinct passenger pigeons (Ectopistes migratorius) seen in 1740 was 3 to 4 miles (4.8 to 6.4 km) long and 1 mile (1.6 km) wide, it was so dense that it blocked out the sun.
