Rubber Boas!

Hey everyone,

Haven't made a post in awhile so I figured I would start one about everyone's favorite under appreciated worm- the Rubber Boa. 2016 with its rain and fairly mild weather (well, being in the Bay Area, who knows what the weather will be tomorrow!) has proved to be quite favorable for Charina. From January until now (May), I think I have found close to 18+ boas in quite a few different areas/counties!

These personable, mysterious snakes were a favorite of mine when I was a kid- would stare at pics of them (along with Zonata) in my field guides and just wish to find one! Well, now it seems they find me!

Just wanted to share some of my favorite Rubber Boa photos from 2016 so far. Nothing too crazy, just some snakes from the area.

1. Massive Gravid female, San Mateo County, May 2016.

The most recent Rubber Boa was actually found by my girlfriend (her lifer!) while we were taking a hike and exploring some abandoned buildings. We found 3 in total, with this being the largest one. Actually, this was actually the largest boa I have ever seen!

Image

2. Yearling, Santa Cruz County, May 2016.

I've been exploring outside of my normal hiking areas and was thrilled to find this little guy in a new area under some wood!

Image

3. Olive green (relatively) adult female, San Mateo County, April 2016.

Just a very clean looking Rubber Boa that was pretty adorable.

Image

4. Large female with heavily scarred/freshly wounded tail tip, Santa Cruz County, March 2016

A very large, typically colored boa from the Santa Cruz Mountains. Under a log on the side of the road.

Image

5. Adult male boa with little to no tail tip scarring, Santa Clara County, March 2016.

The first boa I found while exploring a new area!

Image

5. East Bay boa, Contra Costa County, February 2016.

My first boa from across the Bay! My friend Ryan set up a few pieces of AC near his home and was nice enough to take me out!

Image

6. First boa of the year, San Mateo County, January 2016.

A poorly photographed adult boa from chaparral habitat.

Image

I have caught boa fever. I use to spend my time trying to find and record some of the more "popular" species like Mountain Kingsnakes, but I am now thinking I may have a new goal- boas EVERYWHERE. So many places I've yet to hike in the Bay Area (and well, all throughout Northern California)- might a well add a boa hunt into the mix!

If anyone wants to join on a boa hunt, please let me know!

Please share your boa finds too in this thread!

-Zach

I went out last week with Rich Hoyer down in Corvalis Oregon and learned more about boas (and herping) than I ever thought I would! Stand up guy. I would recommend it to anyone in the area.

Here was a good sized one I snapped down there.

That's awesome Zach. That San Mateo female is a BEAST! Who knew they got like that?!???! Ha ha ha.

So, uh - we got boas in Utah, too. Don't know where all they are, either. Mysterious is right, but there's a little local know-how (e.g., Hoyer Jr lives here). So when you're done over there...c'mon over!

cheers

Boas are a really interesting, I wish I could stumble across them more often but it's a bit of a drive. I've put these up before but here are a few from southern BC.

Love rubber boas! My favorite serpent to herp, and conveniently the most populous snake in the Sierra (well, after crotalus). Thanks for sharing some coasties!

That's awesome you were able to herp with Richard Hoyer! When anyone says "Rubber Boa" or "Contia", I instantly think of him. Would love to head up that way and herp!

The Mateo girl was indeed HUGE. I wonder how many generations of boas on that hillside call her mom!

Utah seems like a very interesting place for rubber boas to reside. I wonder what type of habitat they prefer there? I would love to head over there for some boas (and of course milks).

So awesome to see any herp from Canada, especially boas! What does the habitat look like up there? I would imagine more grassland?

I have yet to see a Rubber Boa in the Sierras (just zonata, lateralis, etc). Will have to make more of an effort!

That would be awesome! Never been before- just wanted
To explore
Some abandoned areas with the lady and happen to find one!

Really love that head portrait.

Rubber boas make me love the ground, the beautiful Cali ground.

The second boa is from a grassland but the first couple are from mid altitude from stumps and talus at the ecotone between pine and fir. That site used to be extremely productive, but homes and traffic appear to have reduced numbers.
Such cool species hope to see some this summer.
Best,
Nick

They are much bigger in the Sierra, compared to the coasties.

You're all killing me, I've been driving all over Northern California this spring trying to find a boa with no luck. If anyone wants to PM me any hotspots I'd really appreciate it.

That sounds like great habitat, all of them! Do you think many boas are being hit by cars due to traffic, or are you referring to foot traffic?

Wow, really? Also, I have never found a "pink" baby along the coast. I have a feeling that pink neos are reserved for the Sierra animals (?)

Keep it up! I have seen over 2 dozen of them so far in 2016 and most have been in chaparral habitat/grassland bordering forests.

Another day, a new spot, another boa!

Had breakfast with my girlfriend this morning up in the mountains and while driving home, spotted some junk on the side of the road. Lilly flipped some junk wood and I spotted this big boa trying to bolt down a hole!

It's a great year to be (or become) a rubber boa enthusiast!

I've found a number of DOR's, there is quite a bit of vehicle traffic now for a mountain back road and people aren't looking for boas.

That's a nice collection from this year, Zach! It's nice to see so much interest in this "classic" American snake.

Thanks, Tim! They are indeed a "classic" snake, aren't they?

Not a boa, but here is a "Boa by-catch" from the weekend-

Nice pics! I am heading out to the Western Sierras not this weekend but the next to do some herping. I hope this recent heat doesn't drive them away!

Good stuff Zack. I managed to find a rubber boa in Yosemite this last week. Flipped it under a rock. It was a cool surprise.

Another day, another boa- New boa at a new spot for me in Marin County, about 10 minutes north of the Golden Gate Bridge! Hoping to find one in San Francisco proper soon!

Cool. That Marin animal is brimming with health.

I just got my lifer Montana boa last week, southeast of Missoula. Saw him from the backseat of my 4-Runner, wife driving, in-laws in the car on a scenic drive. Luckily she didn't smash him, he was near the road's edge. Here's her best cell-phone snap:

Image

On the crawl at 3 PM, air temp 80F, sunny/smoky day. Big male. On a gravel road with west-facing talus and ponderosa/Doug fir timber on one side, and the willowy/sedgy riparian zone of Rock Creek (trib to Clark Fork) on the other. Maybe 3500' elevation? Epic boa habitat.

Good hunting in the city! I would think boa populations could survive alright in little habitat fragments like the Presidio. Rodent populations are probably sky-high due to human subsidy. They may be tainted with rodenticides, metals, etc...but that's another topic entirely.

cheers

Very nice Marin County boa Zach!

Hope you find one in SF someday soon...

Jimi- that is a great boa! And what a cool place to find one!

Jeff- thanks man! It was a beauty! Got many boards set up now in the presidio and at some "historic" (based on CAS records) in the city, so fingers crossed soon!

Great boa finds Zach! I used to look for those when I lived in the Sierra's, and at a single outcrop about the size of a garage we managed to document 39 boas, including juveniles. It was amazing, but other locations yielded similar numbers, as long as you weren't in zonata habitat. While exploring an abandoned logging camp and mill, my wife found a piece of buried black plastic around the base of an old stump. She started pulling the plastic up out of the ground and found 7 boas underneath it. They are truly an abundant species.

Brian, they are so rare in Oregon that they are a protected species.
