Summertime, and the Living is easy...

One of these mornings
You're going to rise up singing
Then you'll spread your wings
And you'll take to the sky

Adiós, Vaya con Dios....
Goodbye, God be with you....

Comparison to the bird literatures in the Internet:

Nesting Habits

Although bird watchers may see the male with nesting material, the female builds the actual nest. The nest is cup shaped and made of twigs, grasses, and leaves. These finches will nest in a variety of artificial and natural cavites such as old woodpecker holes, hanging plants, and occasionally birdhouses. The nest is located 5 to 10 feet above ground.

The female lays 2 to 6 bluish with fine speckling eggs. Incubation is done by the female for 12 to 14 days and the young will leave the nest in about 11 to 19 days after hatching.

During the incubation time and for about five days after the young have hatched, the male, will feed the female on the nest. He does this by regurgitating seed into the females mouth. The female regurgitates the food to the nestlings.

After the young have fledged, the parents continue to feed the young. The female may find a new mate and raise another brood while the male continues to feed the young. House finches have been known to raise more than two broods in a season.

Breeding

During courtship, the male will touch bills with the female. He may then present the female with choice bits of food, and if she mimics the behavior of a hungry chick, he may actually feed her. The male also feeds the female during the breeding and incubation of both eggs and young, and the male is the primary feeder of the fledgelings (who can be differentiated from the females by the pin feathers remaining on their heads).

The female lays clutches of eggs from February through August, two or more broods per year with 2 to 6 eggs per brood, most commonly 4 or 5. The egg laying usually takes place in the morning, at the rate of one egg per day. The eggs are a pale bluish green with few black spots and a smooth, somewhat glossy surface.

In response to mite infestation, the mother finch may lay one gender of egg first, which increases the chances of the young finches' survival.

The female incubates the eggs for 12 to 14 days. Shortly after hatching, she removes the empty eggshells from the nest. The hatchlings are pink with closed eyes and tufts of fluffy down.

The female always feeds the young, and the male usually joins in.
The young are silent for the first seven or eight days, and subsequently start peeping during feedings.
Initially, the mother carries fecal sacs out of the nest, but when the young become older, she no longer carries them all away, allowing droppings to accumulate around the edge of the nest.

Before flying, the young often climb into adjacent plants, and usually fledge at about 11 to 19 days after hatching. Dandelion seeds are among the preferred seeds fed to the young.
House Finches are aggressive enough to drive other birds away from places such as feeders.

Whatever in this article seems to be true with what happened at my house.

The first egg: 7-09-2012
One egg daily for four days: 7-12-2012.
Probably the incubation started here or next day or two (7-13 or 14-2012).
The first two hatchings: about 7-29-2012 or earlier (7-28-2012)
The incubation lasted about 13-14 days.
The fledging of the babies started on 8-09-2012 and all flew off on 8-10-2012.
It seemed that they left the nest in about 12-13 days after hatching.
