Birdwatching

The albatross, which has a wingspan of 12 feet, or 3.7 meters.

It means to remind you of the past when you were young

If they are birds that live in the city then yes

A blue jay exists mainly as a primary consumer, though it rarely eats eggs, potentially classifying it as a secondary consumer.

Yes, it is an informal competition among birders to spot as many birds in a geographical area in one calendar year. There is no formal competition.

bevy

Yes,yes it is.

A male mallard in breeding plumage.

There is no wild duck with a green head and a black body. Mallard drakes have the green head, but the body is bascically buff and brown, with white and a blue or lavender speculum patch on the wing, with a dark brown or chestnut colored chest. The bird you saw may be one of many hybrid species, as for example I have seen seen domestic ducks that have bred with mallards to produce many different colors, including basic black birds.

In exotic species, male Indian runners and crested cayuga ducks are black with green heads, and are allied to mallards. But no North American species.

No.

The Kirtland warbler's eggs are cream colored which are speckled with brown. The eggs are typically laid in a number of either four or five.

Well, chikadees could come and get food from the bird feeder. I have already had a few in my backyard. (I live in Fort Wayne, Indiana if that helps.) Otherwise, I think they just get worms and seeds from the ground.

Pyramid ants have a red head and a black body. These are native to the U.S and are more common in the southern states.

For the same reason babies crawl before they walk. Hopping is easier, they have to learn to walk.

Edit: It depends on the bird. Robins hop, and so do most sparrows. Mourning Doves walk, but they are just as big as a robin. It does not depend on age, but instead species.

3 types, Atlantic, Horned and Tufted Puffins.

I believe it is a killdeer.

Blue birds live all over the world except for in some types of the world

It takes about12-14 days (a week and 5 days- 2 weeks) for robin bird eggs to hatch :)

Bluetits have a relatively varied diet, enjoying foods such as insects, leaves, berries and oily nuts. The following link provides more information on the eating habits of a bluetit http://www.naturegrid.org.uk/biodiversity/birds/titmice.htm

Aviculturist: someone who raises birds.

Ornithologist: studies birds - usually has degree related to birds.

Birder: someone who enjoys birdwatching.

Avian Enthusiast: someone who enjoys being an amateur expert on birds.

You can, but I wouldn't recommend it. All of the traffic might keep the mother from sitting on the nest.

Penguins come to mind. They only live in the southern hemisphere. Very tiny birds like hummingbirds couldn't survive there as they would lose heat too fast.

common winter bird

Yes a bird can. The wood pecker pecks the cactus to get in,then it builds a nest in the cactus.So when they have kids they use the water for their kids and them.

Chickadee is a bird that is in the wild. You can eat chickadees just like any other bird. However, they are small and won't provide much meat. It is best to stick with chicken and turkey which is readily available in the grocery store.

Birds are aves, a special branch of the reptiles. Only birds belong to the aves.They are definitely not mammals.
