Summary of the Day
Of all the SLEWS projects so far this season, the two coldest days have BOTH been with Davis High School at the Yolo Bypass Wildlife Area! Our third and final field day was quite chilly and windy, but Davis students simply put on an extra layer and didn’t seem to mind. We attempted to warm up with a game of PVC golf (all four mentor groups were able to successfully transport the golf ball into the goal!) before heading out to finish our SLEWS project.

We had 106 container plants and 15 plugs to plant, and did quality control (securing tree tubes after some severe wind) on every plant on the four trestles. We thought we’d be lucky to finish all that before lunch. Imagine my surprise when the group finished…at 10:30am! Finishing early gave us time to to do some wildlife observation, and we were in luck because mentor Aaron Haiman is an excellent birder. He showed students how to use and focus their binoculars, and we set off on a birding adventure. Species we spotted included Horned Lark, Savannah Sparrow, Northern Harrier, Peregrine Falcon, Prairie Falcon, White-crowned Sparrow, Red Tailed Hawk, Western Meadowlark, blackbirds, and White-throated Swifts.

We also had time to do a reflection activity. Students found a spot to sit by themselves and had the opportunity to write a thank you card to someone who made their SLEWS experience possible. Students wrote note to mentors, restoration partners, their teacher, funders, guest speakers, and parent drivers – all people who were essential components of this project.

Since it was the last SLEWS Field Day, we had a mini celebration at lunch, complete with cupcakes decorated with trestle mounds and deer antlers! It was a throwback to photos students saw at the beginning of this project, an aerial view of deer trapped on a trestle mound taken when the bypass flooded last year. When the bypass floods next time, hopefully those stranded animals will find it to be much more suitable habitat, thanks in part to Davis students!

After lunch, students gathered to hear from Yolo Basin Foundation’s Corky Quirk, a bat expert. Corky even brought 3 live bats to show students (a pallid bat, a Mexican free-tailed bat, and a big brown bat). Students were absolutely enthralled by her presentation, and asked tons of excellent questions. Do all bats live in colonies? (No) How many babies do they have? (our native species tend to have just one per year) Does pregnancy affect their flight? (probably!) Are bats blind? (no) Do vampire bat bites hurt? (not really – their saliva contains an analgesic!) Corky discussed bats in the bypass and all around the world, and touched on topics like rabies, and white nose syndrome.

Like our first field day, during closing circle, we shared our favorite moment of SLEWS. On the first field day, however, many students answer was “the burritos!”. This time, only one student mentioned burritos – most students mentioned planting, birding, and bats as some of the highlights of their experience. What a great season with Davis High!
