More links, as if we didn’t have enough already:
Sierra Fina: Decent feed.
Sonrisa Farm: Egyptian Arabians
Stone Lily Farm: Thoroughbreds and warmbloods
Twin Acres Ranch: Paints
WinterSpring FArm: High quality and color
Wood Duck Farm: Friesians; four-in-one. A nice touch – the mare’s name is on each screen.
Woodstock: Paints – tweet currently is “Sippa is big as a house! Big giant pregnant belly! Makes me want to waddle just lookin’ at her! :O)”
Here’s my latest updated and culled list of cams – all, as far as I know, are active (except Unbridled, which we’re told will be coming back up) and have at least acceptable quality of images – well, except for Centaur, but maybe they’ll get it fixed so it’s not infuriatingly fuzzed out.
Belladonna: switching between two stalls – one pretty good feed, one okay .
Big Sky: four-in-one. Currently two foals, two still to foal.
Blazing Colours: switches between two stalls
Bowman Ranch: overhead of one stall
Centaur Farms: two screens on one cam – usually, unless one mare’s about to pop
Eagles Ring: minis
Elements Arabians: cam 1; their foal watch page and cam 2.
Evans Diminutive: more minis
EZB Ranch: This one’s got a screen inset to the screen
Fields Quarter Horses: Four-in-one
Fike minis: Outside cam is good quality
Gallo Scarpelli Arabians: Good quality; view through stall bars
Glenhill Farm: cam 1 be alert, it’s got sound! Can be LOUD sound. But a very good cam feed. There’s a slider bar for the sound – hit it ASAP. Their cam 2 doesn’t work for me, but cam 3 does and it appears not to have sound.
Happy Appy Acres: mini mare
Hill Haven: pretty good feed.
Iris Hills: switching between two stalls, one with foal, one with mare yet to pop.

Pinner Hill FArm: Daytime cam shows paddock in pasture. Tweet note ten days ago: “Heaven is due May 5, although she has a Volkswagen in there and my come a little sooner.” Yesterday: "Milk calcium is at 300. Showing some agitation and holding her tail up. We are expecting a foal very soon. "
Poole’s Paradise Hill: Donkeys
Premier Friesians: Not great, but okay. Tweet from two hours ago: “Does anyone have a real big plunger? Cat’s enjoying the leaking milk. Maybe they’ve talked to the foal and made a deal?”
Sierra Fina: Decent feed.
Sonrisa Farm: Egyptian Arabians
Stone Lily Farm: Thoroughbreds and warmbloods
Stony Ford: switches between two – one crappy, one not so bad.

What? Obsessive? Moi??? 
Woodstock Paints says: “Sippa has got WAX! (aka…is dripping milk) From her past history, we should be having a foal by morning!”
Well, Celeste at Pacific Pinto just foaled - very flashy baby! No word yet on gender but momma and baby seem to be doing just fine. 
I notice that Double Freeze at Centaur is pacing a rut in her stall this evening…
Could it be…?
Silver Creek cam 2 – down and looks like she’s going!
Looks like Silver Creek w2as a false alarm, but Premier Friesians is down and looking at her side. But then not taking it any further, alas. Freeze at Centaur is still pacing.
Pacific Pintos: "4/22/10 Celeste has foaled. Bay pinto colt! "
And cute as a button!
Excellent. Although I’m bummed that, after days of watching, I missed the birth.
Double Freeze at Centaur is still pacing. She looks at her side from time to time and is holding her tail up quite a bit. I know she’ll foal as soon as I go to bed!
No It’s happening now!!!
Babys out and moving.
Big black foal with a blaze.
A colt!
Lucky you! I gave up and went to bed a little after 3:00 a.m.
Nice strong vigorous baby, it is.
Cash at Hicks Ranch is looking pretty close. She’s been down, alternating between her side and sternel. She’s up now, but I think there might be a sac showing. Not sure though.
ETA: Nah, no sac, but she’s looking really uncomfortable, pacing and now she’s down on her side again.
Here it comes, person assisting!
Out!
Wow! Momma just about laid right down on the baby. She looks like she’s in pain.
StG
Yeah, she looks pretty uncomfortable. It was a pretty quick birth, and she’s a maiden.
Sippa at Woodstock looks like she’s getting serious tonight…
