Barn swallows lay 3-7 eggs per brood. The have 1 or 2 broods per year.

Crocodilians nest once a year.
In the Southern states, they raise two broods a year, in the North, just one.

Cardinals typically have two to three broods per year. The breeding season usually begins in early spring and can extend through summer, depending on environmental conditions. Each brood usually consists of 2 to 5 eggs, which the female incubates for about 11 to 13 days. After hatching, the young are fed by both parents until they fledge.
Yes, there are a number of hummingbirds that spend part or all of the year in the deserts of the southwest United States.
This year, Brood 19 extends from Missouri all the way to North Carolina and Maryland and reaches down to southern states as well, says Spevak. Thirteen-year broods tend to concentrate in southern states, while 17-year broods tend to stay up north. A true border state, Missouri can get both. Many probably remember that in 1998, during Brood 19's last St. Louis visit, a 17-year brood emerged as well. The two broods hadn't emerged at the same time since 1777 and won't again until 2232. The United States has 22 known broods of periodical cicadas. St. Louis sees a few of them every couple of years. Brood 3 will reemerge in 2014 and Brood 23 in 2015.
Hummingbirds should be fed year-round, as they need a consistent food source. In colder months, you may need to change the nectar more frequently to prevent freezing. It's important to keep feeders clean and filled to support hummingbirds throughout the year.
Sometimes, but normally they seek out whatever females come to the territory they have taken. Bluebirds sometimes raise as many as three broods a year in the southern parts of their range.
No, the correct statement should be "Hummingbirds and barn swallows migrate each year, but bluejays live in one place all year."
Sea turtles hatch throughout the year but mostly in summer.
