Do you know how long wild birds live?
Bird mortality is generally highest in the first year after hatching, and ornithologists estimate that 80-90 percent of baby birds do not live to maturity. Considering one pair of birds alone could have 15-20 baby birds each year, only a few may reach the age of adulthood. If mortality was not dramatically high, bird overpopulation would be a serious issue. A number of factors, including disease and predators, affect mortality. However when ornithologists were able to look at banded birds (birds they marked with a plastic band on the birds foot) over a long period of time, they were able to record average lifespans for various wild birds.
Longest bird lifespans (recorded from banded birds):
- Laysan albatross: 65+ years and still living (the oldest living wild bird on record)
- Arctic tern: 34 years, 0 months
- Brown pelican: 27 years, 10 months
- Great Horned Owl: 27 years, 7 months
- Mute Swan: 26 years, 9 months
- Red-tailed Hawk: 25 years, 9 months
- Great blue heron: 23 years, 3 months
- Sandhill crane: 18 years, 6 months
- Northern Cardinal: 15 years, 9 months
- American Robin: 13 years, 11 months
- House sparrow: 13 years, 4 months
- Wild turkey: 12 years, 6 months
- Killdeer: 10 years, 11 months
- Eastern bluebird: 10 years, 5 months
I had no idea wild birds lived so long (well once they get over that initial hump anyway 😉). -

Nice one @wafercookieflippers @Alansmart and speaking about birds, did you noticed why do birds bob their heads when they walk ? To stabilize their visual surroundings. Unlike us, we depends on eyes movements rather than the head movements to hold the images presented to us while in moving. The back and forth movements on birds are not just random head-bobbing 🐦

Wow, so many interesting facts about birds! Very interesting! Here is another “creature” fact. While this doesn’t have to do with birds, it is still very interesting! Did you know that the shortest lifespan of an insect is only 24 hours? That lifespan belongs to the Mayfly. Within these 24 hours of its life, it is born, finds a mate, breeds, and dies.

Octopuses 🐙 Mythology and superstition have portrayed octopuses as alien beings or evil creatures dwelling in the terrifying dark depths of oceans.
However Octopuses are widely considered to be the most intelligent of all invertebrates. ...
The giant Pacific octopus has three hearts, nine brains and blue blood, making reality stranger than fiction. A central brain controls the nervous system. In addition, there is a small brain in each of their eight arms — a cluster of nerve cells that biologists say controls movement. ... Two hearts pump blood to the gills
