Two Nesting Doves and a Squirrel Alarm, 04-02-19

I got up around 6:15 this morning and headed out to the Effie Yeaw Nature Preserve again. It was overcast and drizzly on and off all day and was about 51° when I got to the preserve.

I was joined there by two of my naturalist students, Johannes T. and Kelli O.  Whenever I take students out, I’m more focused on trying find things for them to see, and explaining what they’re looking at, than I am on trying to get photos. So, I don’t have as many photos to share this time as I usually do. Johannes and Kelli seemed to be interested in everything and had lots of personal stories to share about their own outings and hiking adventures.

We saw several small herds of deer; many of them hunkered down in the grass waiting for the rain to pass.  We also came across a California Ground Squirrel munching on a large peeled acorn, and another one standing on a log giving off an alarm call. That one looked soaked and I wondered if maybe his burrow got flooded.  And we came across a small dead mole on the trail – and they get drowned out often by the river.

We also saw an Eastern Fox Squirrel ripping the tules out of one of the tule huts on the grounds. Hah!  Wutta brat!

At one point along the trail we saw a California Towhee… and then a Spotted Towhee landed on the same part of the trail, so we got to see them side by side, and see how different their field markings are.

Around that same area, we saw a male Mourning Dove flying by with some long grasses in its beak and followed it to where it handed off the grasses to its mate, sitting on her nest on an odd flattened part of a bent branch.  So cool.  The nest is visible from the trail, so I’ll have to keep an eye on it; see if they get any babies.  Mourning Doves can have up to six broods a year!

At the pond near the nature center, there was the paid of Mallards sleeping on log.  That’s a bonded pair, and I’ve seen them every week for the past several weeks; they like resting there.

We walked for about 3 ½ hours and then went on our separate ways.

Lots of Birds Nesting, 03-31-19

Around 7:00 am I headed over to the American River Bend Park for walk. It was about 44° at the river when I got there and was heading toward 70° by the time I left.

It was nice to see that the dirt road to the camping area and nature trails was cleaned up and smoothed out. No more car-swallowing potholes!  I saw some deer and a jackrabbit right when I was heading in, so I felt that was a good portend.

The Black Walnut trees are starting to leaf out and drop their catkins, and the California Buckeye trees are just beginning to squeeze out their panicles of flowers. Redbud trees are flowering, and the Santa Barbara Sedge is starting to show off. I checked out various stands of Pipevine but still don’t see any evidence of butterfly eggs yet… I was happy to see small stands of stinging nettle in the picnic area. Let’s see how long it’s allowed to remain there.  It’s a host plant for Red Admiral butterflies, and when the park eradicates the nettles, they eradicate the butterflies as well.  You’d think they’d figure that out.  It would be a lot easier and cheaper to post a sign about the nettles and have people avoid them, than to kill all of the plants.

I spent almost 20 minutes watching a female Western Bluebird deciding whether she wanted to commit to a nesting cavity or not. She flew up to the opening several times, poked her head in and looked around, but then would back off again. I didn’t understand what her hesitation was and wondered if maybe the hole was already occupied by something. Then it occurred to me that she might not be committing to the spot because I was there watching her, so I walked off a bit, then a bit more. I still didn’t see her go all the way in, but her hubby was sitting in the tree nearby patiently waiting for her to make a decision.

I also came across a House Wren taking twigs to her nesting cavity, and a European Starling poking her head out of her nest.  She’d chased off a Tree Swallow that wanted the same spot.  Lots of cool photo ops today!

I got to see a very large Red-Tailed Hawk in a tree (but she had her face turned away from me, so I didn’t get any good shots of that).  She was so big, I thought at first that she might have been an owl.  As soon as she left, I saw a Red-Shouldered Hawk near the same tree.  As I was leaving the park, I also saw a Cooper’s Hawk chattering in a tree alongside the road.

I walked for a little over 3 ½ hours before heading back home.

The Bucks are in Rut at the Effie Yeaw Preserve, 11-10-18

I slept in a tiny bit this morning and got up around 7:00. After giving the dog his breakfast, I headed over to the Effie Yeaw Nature Preserve for a walk.  It was a chilly 34° at the river!  Got up to about 70° by the afternoon.  The air quality was bad enough today to spark a “Very Unhealthy” purple warning.

At the preserve, the first thing I saw was a small harem of female deer and a couple of fawns, along with a young spike buck.  I got quite a few photos of him doing his “Flehmen Sniff” thing. He closes his nostrils and pulls air in and over the “vomeronasal organ” in the roof of his mouth to pick up on the pheromones of the females around him to learn if they’re in estrus or not. He lifts his top lip because the intake part of the organ is just behind his upper front teeth.

I also saw other deer dotting the preserve here and there including the big 4-pointer (who I think is now a 5-pointer, but I can’t tell for sure from the photos I got of him). He was tucked away on the other side of a field in the shade, so at first, I didn’t see him. When I stepped into the field, though, to get some shots of a Red-Shouldered Hawk (I saw two of them today) he moved, and only then did I realize he was there. It looked like one of the prongs on his rack had been snapped off, but he was still very impressive looking.

I found another older buck in a different part of the preserve, but his rack was really wonky.  On one side, he only had on long prong, and on the other side, he had a 3-point antler with a gnarly-looking eye guard. The doe he was pursuing, though, didn’t seem to mind too much that he was “uneven”…  Several different things can make the antlers messed up like that: the pedicle on the head from which the antlers grow may have been damaged somehow; or the antlers themselves might have been damaged while they were still in their velvet stage and growing; or the buck may have nerve damage in the hind leg opposite from the malformed antler.

You may also notice in the photos that the mature bucks’ necks swell during the rut. Although I couldn’t find any scientific studies about this phenomenon, the consensus seems to be that the swelling is caused by a dramatic increase in testosterone during the rut which affects the blood vessels and muscles in the neck (along with other parts of the body; hah!). The thick neck is apparently attractive to the females, and also helps to cushion the head and body when the bucks joust, absorbing some of the shock when the bucks butt heads. Interesting!

As I mentioned, I saw two Red-Shouldered Hawks in different parts of the preserve today, and I also saw a Red-Tailed Hawk, but that one flew off before I could get any good shots of it.  Inside the nature center at the preserve, I also got to see Orion, the preserve’s Swainson’s Hawk. He’s still a youngster, so doesn’t have his adult coloring yet, but he’s a handsome bird.

Along the usual suspects like Wild Turkeys, California Scrub Jays, Northern Flickers, Spotted Towhees and Acorn Woodpeckers, I got to see a tiny Hermit Thrush in the scrubby brush on the side of the trail. I hardly ever get to see those little guys, so it’s always kind of a treat when I can get pictures of one of them.

There were lots of California Ground Squirrels and Eastern Fox Squirrels around.  The squirrels can have a second breeding season in the fall, and I saw one of them carrying a big mouthful of grass to its nest.  The cool thing was being able to spot the melanistic squirrel (all black) again.  I hadn’t seen that guy for a year.  The last time I saw him was actually on November 22nd last year.  Maybe he only comes out once a year. Hah! (You can see last year’s photos HERE.)

I walked for about 3 hours and then headed back o the car. On my way out of the preserve, I stopped in at the nature center (which is when I saw Orion) and picked up several copies of “The Acorn” magazine published by the American River Natural History Association. My lichen photo is featured on the cover.  Super cool!
