Adair Female #12
Life History

The following is a reproduction of the records kept by Richard F. Hoyer over the lifetime of this snake up until she was transferred to me in the Spring of 2001. Only minor edits have been added and in most cases are noted with [ ] . My comments have been added in Italics.

 

08/26/84

Born on August 26, 1984. Larson Site Female #51 baby #3. Length at birth: 10 5/8 inches.

 

Adair Female #12 was released shortly after birth at Camp Adair near Corvallis, OR as part of a study. She was not seen again for almost 7 years.

06/22/91

Found under tin #31 at C site. Length: 24 7/8 (632mm), Weight: 136.0 grams.

 

Gravid when found. This was likely her first brood, although possibly the second.

06/28/91

Shed skin

08/08/91

Shed skin

09/02/91

Produced brood, ending weight 72.1grams.

 

Note that her weight was 136.0 grams in mid June, and dropped by 63.9grams, or 47% from her recorded weight. Far more likely than not, she weighed even more prior to June, as she began fasting at the beginning of ovulation like as gestating Rubber Boas normally do. Therefore, it is not unreasonable to conclude that she expended greater than 50% of her original body weight to produce a brood. This is an amazing amount of weight loss, but is typical as recorded for other females.

09/04/91

Released where found.

04/08/93

Under tin #C41 with other female. 136.7grams, 25 inches. Tip [of tail] now scarred, body covered with numerous, recent, dirt-encrusted large rodent bite marks, rest of description the same. Palps 4-5 very small ova.

 

Tin C41 is one row over (about 30 feet) from C31 where she was last found, and released 19 months earlier.

04/12/93

Released where found.

05/06/93

Tin #C41, 128.7grams, not measured, put with three females in basement ate one baby vole at 5grams.

05/09/93

Released where found.

07/15/94

3rd row, tin #1 (C31), 102.3grams, 26inches, mottling medium, has 3 huge recent wounds on dorsal surface approx 7,10, and 14 inches from nose. First wound is 35mmX14mm with 10-11 vertebrae exposed some flesh missing [some internal organs slightly visible]. Second wound is 45mmX4mm with 13-15 vertebrae showing. Third is 20mmX10mm with about 7 vertebrae showing. Tail tip crushed-badly chewed up. Large wounds and bite marks suggestive of weasel, possum, skunk, but rodent type marks also seem to be present, esp. at the tip suggestive of ground squirrel or gopher??? Slight healing seems to have taken place. Wounds probably 2-4 weeks old, but look fresh. See here for photo of one of her scars.

07/25/94

Had pictures taken of wounds at O.S.U.

 

After being so severely wounded, she likely would not have survived much longer on her own. This subsequently became evident through the fact she would refuse most offerings of food, and despite force-feeding, continued to loose weight. For most cases in the following entries, Fed means mouth opened and item inserted, and where necessary gently pushed down. This is differentiated from Ate, which is where food was placed in the cage and taken of own free will.
