Camping at Domingo Springs

I spent the 4th of July weekend camping with my family at one of my favorite spots. Domingo Spring in Lassen National Forest. I first visited this site during my graduate school work where I was recording the calls of Evening Grosbeaks, and I have returned regularly ever since. The campground, set among jumbled piles of volcanic rocks and large conifer trees, is immediately beside a wet meadow that Domingo Creek runs through. Near the entrance of the campground is the source of Domingo Creek, and the campground’s namesake, Domingo Spring. This spring is one of the few places I know of where one can drink right out of the land. In my mind, that makes this a very special spot, indeed. We also drove to Willow Lake for part of one day which was lovely. Willow Lake has a floating sphagnum bog where a couple of native species of carnivorous plants grow wild.

Worms Don’t Drown!
Posted in Annelids, Natural History, Outreach, Uncategorized, Youth, tagged Annelids, Drowning, Earthworms, Natural History, Observations, Outreach, Rain, Youth on February 21, 2019| 2 Comments »
Winter rains are sources of terrific fun at my house. My daughter and I love rain walks, and now that she is getting used to a larger bike, rain bike rides are becoming another fun activity to add into the mix.
During a recent rain walk, we were peering into puddles to see what we could see when we spotted a few earthworms submerged in the water.
“Uh oh,” I said “Let’s rescue those worms so they don’t drown.”
“Worms don’t drown.” Said my daughter.
“They don’t?” I asked.
“No, they don’t drown when it rains.” She answered.
I will confess, I was doubtful about this. I have grown up knowing that earthworms come out of the soil when it rains because all their tunnels are flooded. I have also grown up knowing that if earthworms wander into a pool of water, they will drown. So, asked my daughter where she had heard that earthworms don’t drown. She told me that she had been watching a nature show, and that it included a section on earthworms, and it included the information that earthworms don’t drown in water. I was surprised to hear this, and was still a little skeptical.
When we got back to the house, we were telling my wife about our adventures, and the worms came up. My wife also said how sad it was to see worms drown in the rain, and my daughter jumped in with the information about worms not drowning. My wife was as surprised as I was having grown up with the same information on this topic that I did.
But, my daughter was sure she was right, and when we did a little online search it turned out she was absolutely right to be so sure.
Earthworms Don’t Drown!
I could not have been more proud of my daughter at this point. She knew she was right and stuck to her guns. And she taught me that something I had believed was true was actually false, and replaced that false information with truth. So proud!
Here is the new information I learned.
Earthworms need moisture to breath, which they do through their skin. As long as there is sufficient oxygen dissolved in the water, worms can survive for extended periods of time (we are talking three days or more) completely submerged with no ill effect. No one is completely sure why earthworms emerge from the soil when it rains, but one of the leading hypotheses is that they are taking advantage of the moisture above ground to disperse into new habitats and find new mates. The rain allows them to move across areas that would otherwise be too dry and/or too far away for them the reach when it is not raining.
So, if you see some worms wandering around on the surface the next time it rains, maybe crossing the sidewalk, give them a hand and help them on their journey. But, don’t worry that they have been forced out of their burrows by the threat posed by all the water. Because, as my daughter taught me, they don’t drown!
The One-Legged Warbler
Posted in Birding, Natural History, Passerines, Uncategorized, tagged Birding, Camping, Injury, Natural History, Observations, Passerines, Sierra Birding, Upper Blue Lake, Wilson's Warbler on August 30, 2018| Leave a Comment »
I spent this past weekend camping with family and friends. We camped at a spot that I have not been before called Upper Blue Lake in Alpine County, California. This site is about 45 min south of Lake Tahoe, at around 8,200 ft in elevation, and just off the Pacific Crest Trail. It is a pretty spot set in pine and fir trees, and we had a really nice and relaxing time.
The birds around the campground were pretty entertaining. We had Brown Creepers, Red-tailed Hawks, Williamson’s Sapsuckers, Audubon’s Warblers, Mountain Chickadees, Steller’s Jays, and a Cooper’s Hawk in the trees surrounding out campsite.
But one bird was particularly memorable. As several of our group were watching a Williamson’s Sapsucker, when I heard a warbler chip in the trees above me. I found the warbler and saw an adult male Wilson’s Warblers flitting in the branches. As I and a few others watched, I noticed that the bird seemed significantly more clumsy than most. It was very active hoping from twig to twig looking for, and catching insects. Each time it landed, however, it would wobble around, loose it balance, and need to flap its wings a bit to regain its perch. I was starting to really wonder about this odd behavior when something caught my eye. As this warbler was just landing on a twig, and attempting to hold its position, I saw that one leg was gripping the twig. There was only a stump where the other leg should have been!

From what I could see, it looked like the leg ended cleanly at the distal end of the tibiotarsus, or where the “ankle” joint would have been. Most of the time the tibiotarsus was held up in the feathers, tucked out of sight. It was only visible when the bird lost its balance a bit and instinctively reached out with the incomplete leg. A friend of mine was able to snap a few pictures, and in them you can see the bird standing on a branch and only one foot gripping the bark.

I have no idea if this was an injury (seems more likely) or a birth defect (seems much less likely especially for an adult bird). Regardless of how it happened, the bird seemed to be doing ok. It was very active, the feathers looked to be in good condition, and it was vocalizing normally as well.
This was an impressive example of how resilient birds are. I have seen numerous wild birds that have injuries that were severe enough to cripple a mammal, but the birds have healed and are still able to function at a survivable level. For how fragile they seem, birds a tough!
Bats Under the Bypass
Posted in Bats, Birding, Environment, Mammals, Natural History, Raptors, Uncategorized, tagged Birding, Environment, Mammals, Mexican Free-tailed Bat, Natural History, Observations, Peregrine Falcon, raptor, Yolo Bypass, Yolo Bypass Wildlife Area on August 21, 2018| Leave a Comment »
If you are in the Davis or West Sacramento area in the late summer or early fall, and have an evening to spare, go and find a spot where you can sit beside the Yolo Bypass Causeway. This is where highway I-80 crosses over the Yolo Bypass.

Streams of Mexican Free-tailed Bats over the Yolo Bypass
Just as the sun begins to set, you will see an amazing sight. Columns of bat will flood out from under the bypass and stream across the sky in sinuous ribbons. About a quarter of a million Mexican Free-tailed Bats (Tadarida brasiliensis) live under the bypass this time of year, and every night they pour out and spread across the surrounding area to find small flying insects to eat.
These bats are incredible! They can fly about about 100 miles per hour, making them among the fastest mammals in the world! Remember that Cheetahs are the fastest land-mammal, but bats have them beat by a healthy margin. These bats can fly as high as a mile above the ground, and can forage out distances of several miles from their night roost before returning around dawn to sleep. Using their sonar they can detect and pinpoint the exact position of little insects flying through the air and then capture those insects on the wing, at speed!
My wife, daughter, and I joined some friends and went out for an evening visit to see the bats about a month ago. I was a spectacular evening in the Yolo Bypass Wildlife Area. We saw lots of Swainson’s Hawks; herons, egrets, and ibis galore; some of the biggest Western Saddlebags (which is a species of dragonfly) I have ever seen; and then we got to the causeway.
When we arrived, the sun was still a touch above the horizon, so we had some time to stand around the dirt road that runs parallel to I-80 and chat and watch the sunset. We got a very nice surprise when an adult Peregrine Falcon flew past and landed in the top of a tree a little ways to the west of us. I was so excited to see this bird that, in turning around for a better look, I clumsily stepped on my wife toes (sorry sweetheart)!

Mexican Free-tailed Bats as they leave from under the Yolo Causeway.
As the light began to fade, we started seeing little movements under the causeway. The first bats were starting to move. Interestingly, the bats do not wake up, take flight, and simply fly out from under the causeway wherever they happen to be. Instead, they wake up, take flight, and then fly directly under the causeway for a few hundred yards before turning a sharp left, and lifting up into the open sky. I have no idea why they decide to do this, but volunteers at the Wildlife Area know it is gong to happen so consistently, that they can tell you exactly which tree the bats will fly out near.
The numbers of bats moving under the causeway built and built until there were bats streaming along between the support pillars. Then they made that left, and out in to open they came! A snaking stream of bats began raising and twisting into the sky! Thousands and thousands of bats following one another out from where they had been sleeping to look for food. As we watched the seemingly endless flow of bats, we got a very cool surprise. That Peregrine Falcon that we had seen earlier came back. It started strafing through the flow of bats. It was hunting bats!
I have seen this behavior of raptors hunting bats as they leave their night roost on video before, and it is pretty spectacular to see on a screen. Seeing it in real life was thrilling! After a couple of passes, the Peregrine made a quick move to one side, and suddenly it had a bat in one talon! It flew off and out of sight carrying it’s dinnertime snack.
The rest of the bats were generally nonplussed by the Peregrine attack, and keep streaming and streaming into the coming night.
Finally, the last bat that was going to leave had departed, and the darkness was getting deep enough that we would not have been able to see the bats fl by even if they were there, so we piled back into our cars and headed for home.
All in all, a terrific way to spend and evening!
100 Per Month – May
Posted in Birding, Natural History, Uncategorized, tagged Birding, Natural History, Observations, Yolo County on June 1, 2018| Leave a Comment »
This year, 2018, I have set up a little challenge for myself. The challenge is to see 100 or more species in Yolo County each month. Now, that does not mean that the 100 species of February have to all be different species from the 100 species in January. Rather it means that the total number of species seen in each month should get to a total of 100 or more. So, if I see a Red-tailed Hawk some time in January it gets added to the January list. If I see a Red-tailed Hawk some time in February it get added to the February list.
I am hoping this will help me to notice more details as I search to find that next species for a given month, encourage me to visit more habitat types each month, and highlight the seasonal differences as species come and go from my monthly list. This first few months, I have really been enjoying it, and will share what I see with you as the months go by.
Below is my species list from May. It has a total of 97 species, so I did not make my target. This is the first month of the year that I have ended with under 100 species, and it was a bit of a surprise. I did miss two weekends of birding this month which certainly presented a challenge, but I also missed several species that I thought I would see easily. Northern Flicker was one of the most conspicuous misses. I searched and searched for days to see or hear one, and could not find one anywhere! I also visited a spot along Putah Creek outside of Davis that I thought would be an easy place to find Acorn Woodpeckers, but found none. Virginia Rail, Barn Owl, Lincoln’s Sparrow, and an absurd lack of gulls were a few other species that I was kind of surprised I was not able to find despite specifically looking for them.
When I started this challenge, I was slightly worried that I had made it too easy. In January and February I was able to clear the 100 species mark easily, and was thinking about raising my target to 110 species or maybe even 115. Now that spring is ending and summer is just around the corner, and having ended May three species short, it looks like 100 species per month is a worthy challenge after all.
Some of the highlights from the month were a couple of Ring-necked Ducks and a lovely male Green-winged Teal at the Yolo Bypass, a Burrowing Owl that I spotted on the side of an on ramp to I-80 in Davis, a Loggerhead Shrike that flew past me just beside the Yolo County Landfill, and the lovely and colorful assortment of Central Valley breeding birds like Bullock’s Oriole, Blue Grosbeak, and Lazuli Bunting.
With five months down, and my first under-100 total, I am determined to get over 100 species in June! We will see what I am able to find!
Here is my May species list.
100 Per Month – April

Below is my species list from April. It has a total of 103 species, so I made my target! This month was a bit of a stretch for me to reach the 100 species mark. My family spent more time away from home which meant less time here birding. On the 27th, I was only at 89 species. But, I drove around the Yolo Bypass Wildlife Area auto tour route on the 28th and picked up quite a few species including a lot of shorebirds. Some of the highlights from the month were my first Western Kingbird and Caspian Tern of the year, an Eared Grebe that I found at the Port of West Sacramento, a Horned Lark that I happened upon driving through the Yolo Bypass Wildlife Area, and a handful of Semipalmated Plovers at the same location. A notable and surprising miss for the month was American Kestrel. I really kept my eyes open for this species, but never was able to cross paths with one!
I am now 1/3rd of the way through my challenge, and I am definitely continuing to enjoy it. I am looking forward to seeing what I can find in May!

It’s A Bird-Eat-Bird World

My wife, daughter and I were in Berkeley, CA this weekend visiting my mom and some friends. One morning, while we were having breakfast and watching the visitor to the bird feeders hanging not far from the floor-to-ceiling windows, we witnessed a pretty dramatic event.

A female or juvenile Purple Finch.
As we eat our breakfast, a group of three or four Purple Finches were enjoying their’s. Suddenly, a California Scrub-Jay made an ambush attach on the feeder! It flew in through the branches of the Incense Cedar, and startled the finches into a bit of a panic. One of the Purple Finches (either a female of juvenile bird) made a very bad decision, and flew directly away from the incoming jay which meant it crashed into the big windows right in front of us. The jay flew past the feeder, not stopping at all, and landed on a table near the big windows. It seemed from watching the flight of the jay, that landing on the table had been its plan. The finch was on the deck, stunned by the impact with the window. The jay looked down, watched the finch for a moment to assess its condition, and then jumped down, grabbed the adult finch in its beak and flew away toward a large tree that we are pretty sure this bird and its mate have a nest in! That’s right, as if it was pretending to be one of the small hawks or falcons, the jay picked up the stunned Purple Finch and flew off with it!

California Scrub-Jay
This whole event only took a total of about one minute, but it got us all talking and thinking a fair bit about what we had just seen. First off, What a sight to see! All of us around our breakfast table were pretty surprised, impressed, and a few were taken aback at seeing a predator prey interaction at such close range. Secondly, I have never seen a California Scrub Jay prey on an adult songbird, before! I looked it up, and while there are reports of similar behaviors, they are not common. Thirdly, was driving a finch into the window the jay’s plan? The jay seemed like it was aware of the window, as its movements never put it in any danger of colliding itself. The finch was either unaware of the window, or was so frightened by the jay’s sudden attack that it forgot about it. So, did the jay basically hunt the Purple Finch using a window? Jays, members of the corvid family along with ravens, crows, magpies, and others, are highly intelligent and have been observed using tools in a range of settings. So, using a tool such as a known window location to incapacitate prey certainly seems possible.
Regardless of whether or not the window was used as a hunting tool, or if the jay just got lucky, this was a pretty impressive sight to see. And those baby jays had a very big breakfast of their own that morning!

Below is my species list from March. It has a total of 101 species, so I made my target! This month started really strong with 71 species on my list in just the first week. But then things slowed down for the rest of the month. I was delighted to see my first Swainson’s Hawk of the year, but I have not yet found my first Western Kingbird. I had a nice diving duck month that included Canvasback, Lesser Scaup, Bufflehead, Common Goldeneye, Common Merganser, and Ruddy Ducks! Another duck note of interest was that I spotted a few Green-winged Teal, but the Blue-winged Teal look like they have left the area. Additionally, the couple of Varied Thrush that I heard at Wood Duck Lake were a really wonderful treat that I was not expecting!
I am now 1/4th of the way through my challenge, and I am definitely continuing to enjoy it. I am looking forward to seeing what I can find in April!

Below is my species list from February. It has a total of 105 species, which is exactly the same number of species I saw in January, so I made my target! This month was a really nice raptor month including 3 Ferruginous Hawks, 3 falcon species, Sharp-shinned Hawk, and Cooper’s Hawks among others. Cedar Waxwings were surprisingly hard to find, for me, this month. The most surprising misses were Say’s Phoebe and House Sparrow; two species that I specifically tried to find on a couple of occasions.
I am definitely continuing to enjoy this challenge. I am looking forward to seeing what I can find in March!
Here is my February species list.
