Most fledglings do not survive the first migration BUT If a martin can survive the first couple of years they have a chance of living for 7-10 years -but the mortality for younger birds is very high.
One banded bird was documented to live over 13 years.
up to 600 at one time.
They have many predators, one of them being the HAWK, it is one of the few that can actually out fly a Purple Martin. I've seen a few duels in the sky end in victory for the Hawk. I don't see how in the world the Hawk can match his every move as they change direction ever so frequently.The only other predators it has would be animals such as Raccoons, Possums, and Starlings which affect the young mostly. Raccoons and Possums will eat the eggs as well as the defenseless young. I've seen Starling take over an active Martin nest and throw the eggs out the entrance endings any hopes it had.I'm sure there are others depending on which region they reside but that's all I can think of right now.Joe
under lab conditions more then a thousand, in the wild... who knows? much less
It lays one egg at a time. As with other bees it lays many eggs over its lifetime placing each one in a brood cell individually where, once it has hatched the workers can feed the lava until it matures into a new bee.
Yes, many bird species include mosquitos in their diet. Birds such as swallows, swifts, and purple martins are known for consuming large amounts of mosquitos, helping to naturally control their populations.
Purple Martins typically lay between 3 to 8 eggs per clutch, with the average being around 5. They usually raise one to two broods each year, depending on environmental conditions and food availability. Therefore, in a single year, a pair of Purple Martins can lay around 6 to 16 eggs.
Purple martins typically lay eggs once per breeding season. A female usually lays between 3 to 7 eggs in a single clutch, and she may raise one brood per season. After the chicks fledge, they often leave the nesting site, and the birds may migrate south for the winter.
Purple Martins typically have clutches of 3 to 7 eggs, although the average is usually around 4 to 5 eggs. The female incubates the eggs for about 15 to 18 days before they hatch. After hatching, the chicks are altricial, meaning they are dependent on their parents for food and care until they fledge, which occurs about 26 to 32 days after hatching.
A woman will have about 400 eggs in her lifetime.

In it's whole lifetime the average Turtle will lay an estimated 1,800.
Contrary to popular belief, the thought that Purple Martins reduce mosquito population was brought up to promote the products that went along with the birds such as housing, and gourds. http://www.purplemartin.org/update/MosCont.html is research that was conducted to back it up. But don't get me wrong, Martins have many advantages. Just hearing that beautiful song they produce makes it worthwhile to attract Martins to your backyard.
one
it depends but in its lifetime it can have 2 eggs
More than 1000 in its lifetime!

Chickens in Battery farms are bred to lay many eggs during their lifetime. 250 to 300 per year and they are kept for two years. Expect about 600 eggs from a battery or factory farm chicken.
