Many, Many, Many Deer… and a Swarm of Bees, 03-26-19

I headed out to the Effie Yeaw Nature Preserve for a walk.  It was about 51° and drizzly when I left the house around 7:30. Although I carried my umbrella throughout my walk, I didn’t need it. As soon as I got to the preserve, the rain stopped. And by the time I left there, around 11:30 am, the sun had come out and it was about 63° outside. A very nice morning for a walk.

Lots and lots and lots of deer were out today, including some boys who have antler-bumps, and some exceeding pregnant females.  I also came across one doe with a yearling, and the yearling had a bad cough.  I always worry about these little guys. I could see this one’s rib cage starting to show; he might not make it.

I got glimpses of some otters in the river. They were rolling over one another as they went upstream, barking and chirping at one another.  Uhhh… I think they were mating.  “Mating may take place on land but is more likely to occur in the water.” I was worried they were going to drown one another! Hah!

And speaking of drowning: on the Pond Trail, I came across a male Mallard trying to kick the snot out of another male who go to close to “his” female. Mallards aren’t particularly monogamous, but occasionally I’ll see a male who’s very protective of his mate and won’t let anyone else near her. The fight today took place almost a few years to the date of the last time I saw this behavior at the same pond. I wonder if it was the same pair pf ducks.  Rival-guy hightailed it out of the pond after macho-guy tried to drown him and bit him repeatedly on the back and butt. Wow!

The coolest thing I saw on my walk, though, was something I didn’t recognize at first. I saw it from a distance on the Meadow Trail and thought it might have been a nest (like a magpie’s nest), but it was on a weird part of the branches and too odd a shape for it to be a bird’s nest. I zoomed my camera in on it, and realized the whole thing was “moving”, sort of undulating all over its surface. Zooming in further, I realized I was looking at a swarm of bees! It didn’t look like they were building anything’ more like the swarm was gathered around their queen to protect her and keep her warm until she was ready to move on again.

I walked for about 3 ½ hours.

A Beaver and a Loon at Lake Solano Park, 03-16-19

The weather at Lake Solano Park was perfect for walking with my naturalist students; about 49° when we first got there, and then up to about 68° by the time we left. It was sunny, clear and bright outside. My coworker Bill and I took turns pointing things out to everyone, and one of the students, Charlie (who’s something of a plant expert) helped us identify plants.

When I got to the park, Bill and some of the students were already there, and some of them had already spotted an otter in the water. What a great way to start their day! Other highlights during the outing included spotting a beaver in the lake (!) and a Common Loon (!!) which I had never seen there before. We at first thought the beaver was another otter, but it’s large size and big ears brought us to the conclusion of its true identity. It was moseying along in the water, and treaded water for a long time, so we were able to get some photos of it. ((I think I took about 500 photos of its head poking out of the water. Hah!)) Eventually, it made its way to the other side of the lake and disappeared into the shadows. We inferred it might have had a lodge over there although we couldn’t see one.

The loon was a big surprise. At first we were all looking at it, trying to wrap our heads around what we were seeing. Checking through a field guide, though, we were able to determine that it was a non-breeding Common Loon, most likely resting there during its migration through our region.

Deeper inspection of the skull and skeleton we’d found on Wednesday, seemed to indicate that they were from opossums, not dogs as we’d originally thought (based on the canine teeth). There were “too many” small teeth between the canines for the skulls to be from a dog, so opossum was the next best guess. I need to study skulls more deeply – especially the ones of the common animals around here.

I stupidly stepped into the ants’ nest near where we located the Giant Horsetail ferns again. I recognized the spot and tapped on the area with my foot to see if the ants were still there from Wednesday, but nothing emerged, so I thought it was safe to go in there… But as soon as my shadow passed over their nest, they came out in force again. I got bit a few time, but nothing bad. They weren’t Fire Ants; more like red Harvester Ants. But they were still angry about my trespass over their nest and practically “exploded” out of the ground to swarm all over me. The students helped to whack them off my clothes.

On another part of the trail, we came across a large colony of Velvety Tree Ants swarming over an old log. What alerted me to them was a White-Breasted Nuthatch that flitted down onto the log, snatched up an ant, and flew off, flitted down onto the log, snatched up an ant, and flew off several times in a row. Along the ridgeline of the log was a line of winged adults getting ready to take off to establish new colonies… and it was the big winged one the Nuthatch was after. Very cool.

On the lake were Bufflehead ducks mingling with Goldeneyes, and both Common and Hooded Mergansers (along with the egrets, some herons, and Canada Geese). On the shore were lines of turtles sunning themselves; both Red-Eared Slider Turtles and a few Pacific Pond Turtles. We also all got to watch a Belted Kingfisher on the other side of the lake, dive-bombing for fish in the water. Some of the students had never seen that before and were “wow-ing” at the speed of the little bird.

In the ponds, we found Water Boatmen, Mosquito Fish, Bullfrog tadpoles, and a Black-Fronted Forktail Damselfly that was “swimming” along the top of the water before it lighted on some algae to dry off. I’d never seen a winged damselfly swim before! So odd! I need to remember to bring my dip-net with me next time I go out there so I can scoop up some critters to photograph.

We walked for about 3 ½ hours, and all in all, I think I recorded over 60 different species (that we saw and/or heard). It was a good day.
