Q1) Irruption ?

An irruption is when a large group of birds expands its normal range area because there isn´t enough food to feed them.

Q2) Maxilla ?

The maxilla of a bird is its upper jaw - part of its beak. The bottom half of the beak is called the mandible.

Q3) Mobbing ?

Mobbing is when a flock of smaller birds attacks a larger, predatory bird in an attempt to drive it away. For example, lots of wrens might fly at a hawk to keep it away from their nesting area. Crows are another bird that will gang up on an owl or hawk that ventures into their area.

Q4) Pecking Order?

Pecking order is a phrase commonly used with humans, meaning the way that those with power pick on those without power. It is about the same with chickens, where the phrase originated. The "head chicken" can dominate anyone else in the flock, pecking at them and pecking at any food she wishes. The second chicken in order can harass anyone but the head chicken and so on.

Q5) Sanctuary ?

A sanctuary is a place of safety, and that´s exactly what a bird sanctuary. This is a block of land legally set aside for protection of birds and other wildlife. Human use is restricted to help protect the birds´ nests and habitat.

Q6) Plumage ?

The plumage of a bird refers to all of the feathers on their entire body. This includes both the often pretty outside feathers as well as the soft inner feathers that help keep the bird warm. Smaller birds seem to have more feathers per square inch than larger birds, in part to help keep them warm.

Q7) Anting?

In anting, a bird spreads ´ant fluid´ over its body and feathers. It either does this by letting the ants crawl on it, or by grabbing the ant in its beak and rubbing the insect on its body. The acids in the ants helps fight off the mites that live in birds´ feathers. They typically do the anting, and then preen and clean themselves.

Q8) Roost ?

A roost is a spot where birds all gather together at night to sleep. It´s not uncommon to see flocks of birds gather from various places to get together and sleep in safety for the night. They then separate in the day to go off and find food.

Q9) Dusting ?

Dusting is done by many meadow birds, like larks, sparrows, wrens, and owls. Dusting is when one of these birds finds a dusty hollow, and fluffs around in it, rolling in it. Once they have lots of dust on them, they shake and flap to remove it again. It masy also be a way for birds to remove excess oils from their wings.

Q10) Albino ?

Albinos happen in all areas of nature - in plants, in animals, and even in humans. This is a genetic condition that causes pigments not to be created. This results in a creature that looks white, often with red eyes because you can now see the blood vessels in their eyes. Abinos are very rare, and it is more common for a bird to be partially albino.
