Coyotes!
But I was very surprised to hear them just now, sitting here in my classroom planning lessons, because it's three o'clock in the afternoon.
Man are they loud! It's a whole orchestra of howls, concentrated a hundred yards or so away in the scrub along the base of a cliff that runs in front of the school. (So there's little doubt in my mind that it is definitely a pack of coyotes, and not just neighborhood dogs.)
My Google search "Why do coyotes howl?" provided a good clue as to why these coyotes might be howling in the middle of the day: underneath their ruckus, I could hear an emergency vehicle siren in the distance.
It is eerie and forboding to stand outside right now, especially when they are so close. I can't imagine how much more eerie it would be in the dark!

Rattlesnake!
This evening!
Along our favorite nearby neighborhood trail!
We approached it, though keeping a safe distance!
It rattled at us!
It was freaking awesome!!
Here's a picture! Woo hoo!

An Update
In the interrim, here's an update:
1. I had a week of no classes (Spring Break), and in some of that time I managed to do some intended thinking and reading about "ecology". It isn't prudent for me to share my (premature) thoughts, though here is an article about the meaning of "invasiveness" (e.g. plants) that I found really interesting.

2. my wife, parents, and oldest niece came for a visit last weekend. A great time was had by all. (Photo: On the left are Carrie & my Mom, treading cautiously through the treacherous tidal potholes; centered are Madeline and I, reenacting a scene from our favorite movie.)
My wife stayed for the week, and left yesterday to return to Champaign for her last extended stay!!! (Only six weeks now till she joins me in California!). To see photographs from their visit, go to:

Festival of Whales


We left this pod behind and headed south. At about a mile northwest of San Onofre Beach (next to Camp Pendleton), the captain spotted a solitary pair of Bottlenose Dolphins a hundred yards ahead of us. Their solitary travel was something neither he nor any of the on-board marine biologists had ever seen before: dolphins usually travel in pods of tens or hundreds. 
Shortly thereafter, we encountered a small pod of Pacific White-sided Dolphins--numbering probably somewhere between 12 or 20.
And then it's just a couple months' lull until it's time for the blue whales--which are the largest animals ever to have inhabited the earth. (I can't wait!)

Not Bad for My First Week: The True Story of Peltz & the Rhinoceros Auklet
I did not have camera at hand (lesson now learned, of course!). I wanted to take in and remember its details, so that I could later look it up, so I quickly looked over its major features and helped myself remember them by giving each a short description in my head:
2. body shape & size: about the same size as an adult Mallard duck. Shape is penguin or puffin-like.
5. distinctive features: It also had a fine, white feather filament on the side of the head--very distinct.
While standing there with the bird, using my cellphone, I called Laguna Beach Animal Control, and received an answering machine, so I left a message and gave them my thoughts on the bird's identity. They did not show up, but I had managed to flag down a passerby, and collectively, we attracted the attention of the owner of nearby house overlooking the Beach. He informed us of our precise location, which information I passed on to the Animal Control's answering machine--just in case they might receive the message later in the evening and try to act on it after dark.
Sitting with the bird for nearly an hour, I gave up in exasperation around 6:30pm, sensing full well the possible rarity of this bird.
That evening, I posted the details of this event, along with my description, to the Orange County Birding email list. I was delighted to receive, the very next day, the following message from someone on the list, who is also affiliated with the Laguna Beach Animal Control:
"We received a Rhinoceros auklet (Cerorhinca monocerata) from Laguna Beach animal control yesterday evening at 7:30pm. I believe that is the same bird that you saw. Unfortunately the bird did not make it. It will be going to Kimball Garrett at the Natural History Museum for their display."
I couldn't be more smitten with myself.

Alas (for some), Shakespeare Knew His Starlings Well
Going about my daily activities today, I was struck by the fact that I noticed STARLINGS in several places around town. Now, I know that these are common birds (estimated 200 million individuals in North America alone, with a range covering most of the continent), but even so, I think I'm almost always attentive to what types of bird I'm seeing about me.Sibley's Bird Life & Behavior (one of the holy scriptures for North American bird enthusiasts) reports that whether starlings migrate depends on how far north they are, but on this it does not elaborate further.
It's also amazing to contemplate that every single starling in North America today is a descendant of the small population of mere dozens (~60-100) released in Central Park in 1890. (you can find this fact cited everywhere--Sibley, Audubon guide, etc.) How bizarre that apparently the motive for this was to introduce New Yorkers to all of the birds mentioned in the plays of Shakespeare! One Eugene Schieffelin, a member of the Acclimation Society of North America, is responsible.
And did you know that starlings are adept at imitating sounds? It's true. They often imitate birds of their surroundings. Perhaps not surprising then to learn that they are closely related to Mynabirds (both are in the "Sturnid" family of songbirds). It's this ability to imitate which led Shakespeare to reference them in his play Henry IV, read the quote here.

A "Mantidote" for the Wintertime Blues?
Despite the dark pleasures of autumn, which I alluded to in my last post, we know that it all comes to an end about this time November. Strong winds will have stripped that very last vestige of life—the leaves—from the surrounding landscape, and one is left coping with winter’s stark dormancy. This is certainly a cause for depression among creature-lovers.
But mope not, because if you act now, you can preserve one of summer’s treasures to last you well into the winter season. And it’s as simple as this: Go outside right now and catch yourself a praying mantis.
The fact is, as one of the largest insects in North America, praying mantises make a particularly symbolic piece of warmer weather memorabilia. They’re also a great wild animal to collect at this time of year. And here, I think, are the top three reasons why:

(Jerry the Praying Mantis, munching on a beetle larva.)
Number 1: They seem to be readily abundant. That’s undoubtedly something to do with their life cycle: females lay up to 300 eggs, with some hatching in small intervals. And that brings us to...
Number 2: They’re just going to die anyway. That’s because they hatch out in the spring, spend all summer preying (and “praying”), mate & lay their eggs in the fall, and then promptly die from old age or frost, "whichever comes first”.
And finally, Number 3: They are simply amazing to behold. I know, because I kept one last year—his name was Jerry. Fascinatingly, mantises are one of the few insects that can rotate their heads. They also appear to have excellent vision (their eyes are a curiosity unto themselves), and a mantis’ motions and behaviors seem almost as intelligent as those of a small vertebrate.
Of the four or five people who read this blog, I know I’ve got at least one predator-lover out there (you know who you are), so I’ll now say something a bit gory regarding how a praying mantis captures and consumes its prey. (The faint of heart should read no further.) Jerry would hang upside down and ‘swoop’ his spiny forelegs down to capture an unsuspecting cricket. Grasping it tightly to the point that it could not move, he would then chew a small, rectangular incision into the top of the cricket’s thorax (just below the vestigial wings), and proceed to munch the life right out of it. It’s awesomely gruesome, and guaranteed to send shivers right down your spine! (In fact I just got shivers merely thinking about it again.) Happily, no mantis poses any serious threat to human beings, though the mandibles can deliver a painful pinch, so just remember not to be foolish (like I was) and pick them up.
By the way, once your praying mantis finally kicks the bucket, you can easily preserve him for years (and quite nicely) with ethyl alcohol or formaldehyde. Barring that, rubbing alcohol will keep him looking like a sharp souvenir for several months.
Happy bugging, everybody!


PS: To prove to yourself what awesome predators praying mantises are, be sure to check out this website, Praying Mantis Makes Meal of a Hummingbird (it's for real!).
Update: From Wikipedia, more excellent photos of mantids here, including a link to a YouTube! video of a mantis capturing a cricket.

Death Becomes Autumn
If you’re a fan of creatures and you live in a place that experiences winter—I mean real, lifeless, snowy abyss kind of winter—now is about the time of year when it starts to hit you that you’d better say your goodbyes. There is no better symbol of this time of year than the ambience of the Halloween holiday. For animals, the ominous stench of death is in the air. Plant food sources are going dormant, the night air freezes, and the most one can hope is that he has sufficiently fattened himself up in his previous months of (relatively) carefree existence.The cloud of death sends amphibians scurrying for shelter under rocks, logs, and underground burrows. Some insects and spiders spin themselves in silken cocoons, perhaps desperately clinging to the belief that they are constructing insulation, not their coffins. Other insects simply give up, sitting patiently while the cloud of death descends upon them, assured by the sight of their eggs (which will weather the storm) that their existence till now has not been in vain.
I don’t here wish to be down on autumn or such “Halloween ambience”—the fact is, I love this time of year. (Along with spring, summer, and winter, autumn is my favorite season.) It’s hard not to love the thrill of the eeriness that accompanies the impending dormancy of life, since we all know that we don’t have to take it seriously—spring will come again.
