(1) The bird must have been within the prescribed area and time-period when encountered.
(2) The bird must have been a species currently accepted by the ABA Checklist Committee for lists within its
area, or by the A.O.U. Checklist for lists outside the ABA area and within the A.O.U. area, or by Clements for all other areas.
(4) Diagnostic field-marks for the bird, sufficient to identify to species, must have been seen and/or heard and/or documented by the recorder at the time of the encounter.
What's about the webcams?
Nowhere in these rules I found anything that prevents me to add on my life list a species seen on a webcam . Rule 1 specify the location of the bird, not the observer, rule 2, 3 and 4 are irrelevant, and rule 5 is actually a lot in favor on this particular form of twitching, because you actually don't use any fossil-based fuel to see the bird.
One might argue that "encountered" specified in rule 1) actually imply being physically present to observe the bird.
Are you kidding?
Plus, nobody said that "encounter" meant "in real life", rather that "virtually". Nowadays, lots of people meet virtually "friends" who live thousand of miles away, thanks to social networking websites such as facebook. So I think a webcam based encounter is indeed a real encounter.
That opens a new world of possibilities, isn't it?
look at a feeding station in California, and here we are!
While looking at that webcam, I was able to find a bird I could recognize and identify (well at least I think) : the green jay! That's one more lifer on my list!You feel a little bit overwhelmed by the number of hummingbirds? I am too (I need to find a book about South American birds before to really work on that one). So I choose to take a short trip to Antartica , because I need a few penguins on my list
