Q: Why should you not set fire to peregrine falcon eggs?

Forfeit: Because they're an endangered species (they were taken off the endangered list just under five years ago)

A: Because you'd be wasting your time.

Info: Studies of the eggs have found traces of chemicals that are used as flame retardants, polybrominated diphenyl ethers (PBDEs). PBDEs have also been found in sperm whales and other marine mammals.
A peregrine's diet consists solely of other birds and there are two potential reasons for their having eaten the chemicals. One is that shorebirds such as wading ducks (which are a peregrine's main prey) might be taking up the chemical when eating invertebrates that live in the sediment on the shore, or that they're swallowing the chemically-contaminated sediment itself. The other suggestion is that songbirds such as thrushes and doves, that are favoured by falcons living in southern Sweden, might be eating PBDEs in worms exposed to soil that has been contaminated by sewage used as fertiliser.

I posted this on the Bloody thread in the Other Place, but it suddenly occurred to me that we might not have had this factoid here yet.

An early name for the windhover was 'wind fucker'.

This term is used to good metaphorical effect by Chapman, in his introduction to his translation of Homer, where he mentions indignantly "a certaine envious Windfucker,"

that hovers up and downe, laboriously engrossing al the aire with his luxurious ambition and buzzing into every eare my detraction - affirming I turne Homer out of the Latine onely, & c - that sets all his associates and the whole rabble of my maligners on their wings with him to bear about my empaire and poyson my reputation.

Apparently Samuel Pepys also used this term for somebody who pissed off his friend, but I don't know whether there was also a bird connection.

Birds have an egg tooth they use to break out of their shells, these fall off after birth. Here is a picture of a great horned owl's egg tooth -

Some reptiles - e.g crocodiles - and mammals such as the echidna, an Australian relative of the platypus also have an egg tooth. Crocodiles reabsorb their egg tooth in the days after they hatch.

The act of pecking through the shell is known as 'external pipping'.

No, it was definitely an f not an s - the word having the connotation of riding.

A bird which is able to leave the nest shortly after hatching is nidifugous. That's a rather satisfying term!

... and its antonym is nidiculous.

That's very good. Parent bird (exasperated): "Oh, stop being so nidiculous!"

Not sure if it's the done thing to ressurect such an old thread but wanted to add something to the longevity note back a few posts.

The longest lived bird is the Manx Shearwater (Puffinus puffinus [Brünnich, 1764]). A bird ringed (banded) in County Down, Northern Ireland was at least 49yr 11m old.

This figure refers to the time between when it was first ringed (1953) and when it was recaught in 2003. As it was an adult when originally caught it's true age will be at least a year higher.

I certain that I read that the Kiwi has an extremely short beak, as it should be measured from the nostrils to the tip of the beak.

I will have to do some digging on this one...

You are indeed right - it's nostrils are right at the tip - like a human nose.
