The obvious use of a birds bill is to feed itself. Name 2 other uses of a birds bill

To clean (preen?) itself.

To defend itself or attack an enemy.

Yes Imberbe.
Also, in some birds, they are an extension of the plumage and are used in courtship eg, the hornbill family. And in the white stork, it used for communication - they clap their mandibles together to make a staccato greeting for their mate

Many eagles such as i.e. the Wahlbergs eagle, are known to line their nest with green leaves. This is often replenished.

Name two out of three possible motives for this behaviour.

1 To advertise their presence to other eagles- the green is easily visible to soaring birds
2 to keep the nestling warm?

Hygiene? Keeping the nest clean(er) by putting fresh leaves in it?

Hi Guys

I will give it a shot

To keep the nest clean
maybe to keep the next camouflaged.

:clap: Truly a team effort! :clap:

Three main reasons have been speculated upon.

1. The chemicals (aromas) in the leaves chase insects and parasites from the nest.

2. The leaves isolate the nest from below protecting the eggs or chicks from drafts.

3. The leaves stop pieces of meat dropping in to the nest structure, where it could decompose.

Giving this one to Karl Jaacks!
:clap:

Hi Guys

The legs of the Marabou stork white.
What is the white?
What is the purpose of it?

Karl

On very hot days marabou storks pass urine onto their legs. It is assumed that as this warm urine evaporates, it has a cooling effect on the bird.
