CAW!
I'm unable to venture out of the cities and into the great woods and lakes that the state is known for. The city does not have much to offer. Bitter cold chases away all my beloved critters. My friends say I am not looking hard enough, and perhaps I'm not. However, the city does have plenty of hawks. Lots of hawks in which my small parrot panics and flock-calls at frequently. Poor bird.
Yet just as I was thinking that piece to my heart was left behind, as if they knew, the crows came. Thousands of them perched on every branch and wire and windowsill as far as you can pan. It's such a thrill to see!
Smarts are what I've always cherished crows and ravens for. And boy are they smart, flocking like this. Safety in numbers, that's for sure. What predator wants to mess with thousands of crows? The eats are perfect and the options for a mate are plentiful. Why not?
Crows and ravens have a lot of stigma to them, but no need to fear. These birds are fun and would rather watch you as you do them than harm you.
Just don't drop the bread!
Here's some articles and information:

1973 Liz and Gary Doyle "Thylacine" footage analyzed.
Enhanced footage received
In late 2009 I was supplied with a restored version of the Doyle footage. I do not have details to hand of the work which was carried out on the footage, but can source these if requested.
This analysis uses the best quality version of the Doyle footage that I have seen to date.
Analysis
This analysis is a straightforward comparison between frames from the Doyle footage and David Fleay's footage of a thylacine circa 1933.
The following key diagnostic features, visible in the Doyle footage, are those that most pursuade me to argue that the animal in the Doyle footage is a thylacine, albeit on the mainland of Australia circa 1973:
- The proportion of the pes (hind foot) relative to other bones in the hind legs and relative to the rest of the body
- The proportion and posture of the tail relative to the rest of the body
- The shape of the hindquarters
- The depth of the neck and chest
The above features can be directly compared with known thylacine images and footage. Unfortunately there is no known footage of a running thylacine, so the "kangaroo-like" posture exhibited in multiple frames cannot be attributed to the thylacine with any certainty. The posture does, however, align with descriptions of the thylacine resembling a kangaroo or wallaby.
It should be noted that there are additional frames, not included in this analysis, which also show the key features being highlighted here.

Australian Thylacine; resurrected from extinction... almost.
When he was director of the Australian Museum, Archer set off, armed with gene technology, in the hope that he could bring back a Tasmanian tiger or thylacine. Others continue that hunt while Archer has fixed his sights on another extinct native; he will not say which: "The team that's been working on this now for three years has sworn in blood that we won't mention what it is."But the optimists on the team, and Archer is one of them, think they may be ready to go public with a world first as soon as this year. Already, he says, they have managed to get the animal's DNA to reactivate, an essential step on the path to cloning. He is cagey when asked why this unidentified animal is a better prospect than the thylacine: "Suffice it to say, we're working with slightly better material."
