If you think our Birdorable birds are cute as adults, what about when they are babies? Here are some baby photos (shared via Flickr) of the House Sparrow. House Sparrows are widespread across the planet, seen as pests in some countries where they are invasive, while they are struggling for survival in parts of their native Europe. For example, House Sparrows are considered endangered in the Netherlands. Tomorrow, March 20th is World House Sparrow Day. The theme for WHSP 2010 is We will save our House Sparrows and the day is meant to raise awareness and draw attention to the plight of this once-common bird and its decline in much of its natural range.
