Garter grand slam in just 1 hour
I went bear hunting with my dad in southern Oregon last week, and we passed through Del Norte County on the way.
On the east shore of the Smith River (just a little north of where Highway 199 crosses it), I flipped an Oregon Garter Snake, T. atratus hydrophilus.
Garter #1: 19 mid-body scale rows, 8 upper labials, and 10 lower labials:

Then I flipped another rock a couple feet away, and got one with completely different coloration. This appears to be the Coast Garter Snake (T. elegans terrestris)
Garter #2: Mid-body scale rows 18/19, upper labials 8, lower labials 10.

I headed inland from the river a few hundred yards, when I got to an interesting habitat with rocky formations in a clearing. I flipped three garters there, all of which appear to be Northwestern Garters (T. ordinoides), though their counts and coloration are all over the place.
Garters #3 and #4
#3: 17 scale rows, 8 upper labials, 9/10 lower labials
#4: 17 scale rows, 8 upper labials, 8 lower labials
rest of photos here: http://www.naherp.com/viewrecord.php?r_id=144600
Garter #5: 17 mid-body scales, 7/8 upper labials, 8/9 lower labials
rest of photos here: http://www.naherp.com/viewrecord.php?r_id=144606
Finally, I hiked along the road a little ways further, and flipped another garter double under a rock. This time I got a Valley Garter Snake (T. sirtalis fitchi), along with another Northwestern.
Garter #6:
Garter #7: 17 mid-body scale rows, 7 upper labials, 8 labials

4 species, including a lifer subspecies, all within 350 yards and 1 hour. I really didn't expect that!

Re: Northwestern Garters or Western Terrestrial Garters?
WoW! You hit the Garter Snake Bonanza.
#1. Oregon Aquatic
2. Perhaps a Valley Garter or Terrestrial. ???
3. Northwestern
4. Northwestern
5. Northwestern
6. Valley / Northwestern Hybrid... Upper body that of Valley Garter while the latter portion is Northwestern Gater...
a very strange snake indeed
7. Northwestern

Re: Northwestern Garters or Western Terrestrial Garters?
Although I have never herped down in that area, I am very familiar with the three species of garter you are working with here although not the coast garter subspecies of elegans. Here are my ID's
Garter #1: T. atratus
Garter #2: T. elegans -
Garters #3 and 4: Both are T. ordinoides
Garter #5: T. ordinoides
Garter #6: T. sirtalis - I edited this one. The other snake in the photo confused me when looking at it.
Garter #7: T. ordinoides
How was the bear hunt?

Re: Northwestern Garters or Western Terrestrial Garters?
Josh and I hit the post at about the same time. I’m bowing out from Number#2 since i have seen neither Valley nor Terrestrial Garters in Del Norte County. So, I think the only one that is arguable is the Valley X Northwestern Hybrid... that snake is awesome! Josh says T. sirtalis, I say an Awesome Hybrid ... If it got me Josh, I will never tell
Re: Northwestern Garters or Western Terrestrial Garters?
The odd looking one... #6. I'm going to say Valley Garter.
I agree with both Joshua and FN on #1. Definitely atratus. If you look at the eye, it has a more 'fish-like' appearance to it, which is probably the best indicator for atratus.

Re: Northwestern Garters or Western Terrestrial Garters?
That's awesome! I didn't even think about T. atratus being a possibility. Too much time in southern California and northern Oregon! That ones a subspecies lifer for me.
So the question is now whether #2 is a T. elegans or a T. sirtalis?
If it's elegans, then I got all 4 garter species in 1 hour, with 2 five feet apart and the other 2 under a single rock just 350 yards away? Dang, that's incredible! What that says about their ecological niches is interesting.

Re: Garter ID question - grand slam in just 1 hour?
Weather was quite hot, so bear hunting didn't go well. It was the 3rd time my dad has taken someone to that locale in the last 5 months, and the first time that neither person got a bear.
But I saw 20 herp species, with several lifers, so that went great!

Re: Garter ID question - grand slam in just 1 hour?
Here is a top view of the head of #2
Re: Garter ID question - grand slam in just 1 hour?
As the others noted regarding the ordinoides and atratus.
#6 is two snakes (ordinoides and sirtalis), not a hybrid.
#2 is a terrestris, though very strange in that it lacks a vertebral scale row (18 rows)

Thank You, Jeff
Re: Garter ID question - grand slam in just 1 hour?
Thank you Jeff! Are you familiar with any other localities that could produce ordinoides, sirtalis, atratus, and terrestris within yards of each other?
p.s. - I was coming up with several ordinoides in that locality that only seemed to have 16 scale rows. This confused me greatly and made me wonder whether I could count. Do you think there's any possibility that hybridization events in the past could lead to that, or is it just a tame genetic fluke?

Re: Garter ID question - grand slam in just 1 hour?
Regarding sympatry: My only field work in the Del Norte area has been winter salamander hunts, so I can't answer whether or not 4 species together is rare or not. In the Bay Area there were places that one could find three together, but that was uncommon.
Garter snakes tend to have a scale row reduction between the neck and the tail, usually from one of the lateral rows dropping out on each side. If one drops out more anteriorly than the other, you would end up with an even scale row count, and that would occur with some regularity. The lack of a vertebral row, though, is a rare defect.

Re: Garter ID question - grand slam in just 1 hour?
Thank you for that explanation. Yes, the in the Northwesterns it was a lateral row that was missing on one side, not a vertebral row.
Re: Garter ID question - grand slam in just 1 hour?
In summer 1991 I worked all over the USFS-administered parts of the Smith River watershed in Del Norte County. It was routine to find all those 4 taxa in a work week, but I don't recall finding all right together at once. Usually I'd get a couple taxa in the creek and the others up on the ridge-roads. Sirtalis (the second-least common) would do both, the elegans (the rarest, but not at all rare) were the most likely to be far from water. From memory, the biggest streams (ones with a wide hot cobble zone with backwater pools, side channels etc) had the highest garter diversity. And numbers.
FWIW the elegans I found, while genetically probably intergrades, were phenotypic mtns not coasties. Even pretty close to the coast, mileage-wise. The ecological gradient there is pretty steep, you get out of the redwood/fog zone and into the heat right quick.
Nice country, good for you for getting into it. Go back and get some more!
Did you guys use hounds, or what?
Cheers,
Jimi

Re: Garter ID question - grand slam in just 1 hour?
No hounds, just still-hunting and watching likely travel routes and feeding areas.
My dad will be getting back out this weekend, but I won't be going. Hopefully he scores - more bear meat is always a good thing.

Re: Garter ID question - grand slam in just 1 hour?
I've seen a few T. e. terrestris that look like your number 2 out in my neck of the woods.
I don't have 4 species by me, but I have attratus, sirtalis and elegans that can easily be found within a mile of each other, though I've never seen more than 2 species within yards of each other... sirtalis/attratus and elegans/attratus combos have been at the same pond or creek. I do know of a couple spots where all three could happen...

Re: Garter ID question - grand slam in just 1 hour?
Got my mini-slam today. All three county species (Santa Clara) in about a half hour. My first was an adult red-sided that I missed photo'n'.
Thamnophis atratus zaxanthus
Thamnophis elegans terrestris
Thamnophis sirtalis infernalis and YOY all 7" of it!

It's not Bear Season?

Re: Garter grand slam in just 1 hour
Oregon has two bear seasons - one general one in the fall, and a number of special hunts in the spring. The Fall season runs August to December, and the Spring season runs April to May. My dad got a bear last December in the Fall season, and my brother-in-law got one in April in the Spring season, and we hunted April/May in the Spring season.Fundad wrote:It's not Bear Season?

Re: Garter grand slam in just 1 hour
For whoever may be interested but not know much about bear seasons - spring bear hunts can be controversial with many groups enthusiastic about bear conservation (including bear hunters; and by no means just among the animal-rights type groups) so agencies are often loath to create one. Mainly it's about accidentally orphaning dependent cubs, and/or having adverse impacts on population abundance. Anyway, black bears can be pretty high-conflict (with people), especially when their numbers are high, so sometimes it's necessary to knock them down a bit to moderate the conflicts among different people & between people and wildlife. To get the level of damage they're causing back down into "tolerable" range, and out of "intolerable". I suspect in Oregon the bears are hammering young timber stands, and perhaps also orchards/vineyards and bee hives. Just a guess, all are things bears (and Oregon) are known for. Oregon is like bear Nirvana, especially with what humans have done to the landscape.Quote:

Re: Garter grand slam in just 1 hour
Breaking with the strong consensus, I have someone who thinks that Garter #6 is a Coast Garter Snake Thamnophis elegans terrestris, rather than a Valley Garter Snake (T. sirtalis fitchi).
What do y'all think? I had considered it a Valley Garter on general gestalt, but he seems convinced and a couple of other people I've shown it to now are on the fence or leaning in his direction.
The red is on the scales and irregular on the sides of the body, rather between the scales or bleeding out of the interscalars. 8 supralabials.

Re: Garter grand slam in just 1 hour
Garter 6 looks like a valley to me, but has 8 labials rather than 7. Patterning is very off for the coast subspecies though, so i'll stick to just an abnormal valley
Re: Garter grand slam in just 1 hour
Valley Garter... 100%
Re: Garter grand slam in just 1 hour
Here's a head comparison chart from Gary's site http://www.californiaherps.com/snakes/i ... scales.jpg .
Re: Garter grand slam in just 1 hour
Just because... the one second mini-slam exists (3 species).
Re: Garter grand slam in just 1 hour
Nice!
I got the mini-slam on a Canadian island last summer. T. ordinoides and T. sirtalis pickeringii together and then T. elegans vagrans 40 minutes later.
I think I could get the mini-slam in NW Oregon but haven't even managed all three at the same locale yet, much less same day. There's one spot I'm sure all three are around though, just have to get there more.
But I'm pretty sure that little corner of NW Cali/SW Oregon is the only spot where a 4-species slam is even possible, at least for the coastal states. Looking at the range maps there might be a spot where cryptosis, elegans, eques and rufipunctatus all coincide. Don't know about habitat though.
Re: Garter grand slam in just 1 hour
If you counted subspecies, I could do a half day, SF Bay Area 5 snake slam:
1. Thamnophis elegans terrestris
2. Thamnophis atratus atratus
3. Thamnophis atratus zaxanthus
4. Thamnophis sirtalis infernalis
5. Thamnophis sirtalis tetrataenia
If you took a full day, you could do 4 species, 9 sub slam by doing Bay Area and north a few counties:
1. Thamnophis elegans terrestris
2. Thamnophis elegans elegans
3. Thamnophis atratus atratus
4. Thamnophis atratus hydrophilus
5. Thamnophis atratus zaxanthus
6. Thamnophis sirtalis infernalis
7. Thamnophis sirtalis tetrataenia
8. Thamnophis sirtalis fitchi
9. Thamnophis gigas
It would also be possible to do a 5 species 1 day slam:
1. Thamnophis elegans
2. Thamnophis atratus
3. Thamnophis sirtalis
4. Thamnophis gigas
5. Thamnophis hammondii
Not that I would ever try it with $4/gallon CA fuel prices and Bay Area traffic.

If you were trying to pick off five species in a day though, wouldn't gigas/couchi be easier to combine than gigas/hammondii?
If you really wanted to be crazy with it, get a gigas from the northernmost point of their range in the early morning, drive east to the SN foothills to pick off a couchi in late morning, and then you could be over to the coast by early evening and pull off my slam for a 6-garter day.
