The
question then, Why 3 billion Birds Have Lost in North America? The
answer is combination factors, but mostly relate to:
-
decreasing of bird habitats
-
using of pesticides that killed insects as food sources for birds
-
eaten by predators such as wild cats
-
accident like glass collisions
- climate changes
Habitat
is great important for birds, not only to live, but also to find
food, rest and raise the chicks.
Loss
of habitats mainly due to agricultural expansion, and might also
because of property and industry development, especially in sub urban
areas.
Now,
my wonder about reduction of bird population in my backyard is
getting answer. 6 years ago, I saw a quite lot of birds.
In
the last few years or this year around, especially during spring
season, I just see couple of hummingbirds, and I did not see any
woodpeckers at all.
How
about you? Do you aware that less birds in your backyard or any where
else?
