Talking of crows...

13 things you didn't know about crows, from the well-known and respected website, 'For the Love of Crows'.
With supplimentary comments to the author from john.

1. Crows are believed to be the most intelligent of all birds.
How do you know this? Have you caught them reading Proust? Or wearing glasses?

2. There is no way to tell by physical appearance alone, as to whether a crow is male or female.
You could just wait to see who mounts who.

3. A crow can easily identify another crow in the distance, during the day, because black is very visible during the day.
Yeah... and also crows do tend to look reasonably alike, they're not too easily mistaken for a Chihuahua for example.

4. Crows will eat just about anything.
What do mean anything? Cars? Marzipan? A small child? How worried do we have to be here?

5. Crows are very social in nature.
In what context? Are they your regular drinking partners? Are you basing this on a tendency to sit around in groups and caw a lot, because you could then say the same for builders.

6. The male will fluff his feathers, strut, and fly by, in his attempts to win over the female.
I'm a bit unnerved now, do you dress up and enact this? or just film it? How far do your feelings go?

7. Once mated, crows usually mate for life.
Sure, they all say that at the beginning, but don't you listen to him! Those crows will say anything to get their beaky way.

8. There are currently only 14 Hawaiian crows in the wild.
Are you sure this isn't the same crow flying past 14 times with a colourful shirt on?

9. Crows will often gather together and mob an offending or intruding owl or hawk.
Who is writing this? Are you an actual crow that learned to type? Is this a threat to birds everywhere? Because it's unlikely they'll read it.

10. Crows are extremely intelligent, quite possibly the most intelligent of all birds.
Only 'quite possibly' now? What happened? Did you just see a crow banging his head on the glass or drinking bleach or something?

11. It has been recently discovered that crows have been making use of tools in their daily activities.
I'm sorry what? And what kind of tools? Spanners? Rakes? Powerdrills?

12. Crows have an extremely good memory, 'A crow never forgets'
I think you might mean an elephant. Not to worry, they are easily confused. For future reference there is an easy way to tell them apart: tickle their soft feathery underbelly and if you get stampeded to death, it's probably not a crow.

13. Crows have been known to be able to count.
...and now you've crossed the line. Counting crows? It's the name of a band, not a scientific fact. Don't you think crows have better things to do than count? Actually they probably don't. Hmmm... fair point. If I was a crow I might take up a hobby.
