Rotary Nature Center Temporarily Closed

If you’ve been by the Rotary Nature Center of late, you may have noticed that the Center has been closed. The building is undergoing inspection and assessment, and is slated at the very least to getting a thorough cleaning. Animals have been relocated from the building. At this point (Nov of 2017), we are still waiting to hear from the City when the center might re-open, and in what capacity.

Lake Spot: the Rocky Shore

A couple of years ago they finished the shoreline from the Boating Center up to the Geodesic dome. There’s a nice wide path, some benches looking over the lake, and new landscaping around the parking lot, and a healthy bit of shoreline between the path and water. It can be a good spot to see the comings of goings of birds and boats if you are so inclined.

Parts of the shoreline are still fenced off — letting plants get situated and take good root, I presume, there is a path of old rip wrap and stone set on dirt where one can sit at the shoreline and take it in.

I found myself there the other day on a lovely fall day, I unintentionally flushed a Green Heron from the bank. It did my the favor of sitting on a white float for a few minutes, a rare chance to hang out with the most elusive heron of the lake.

I’d passed a Great Blue Heron earlier in the day sitting in shallow water seemingly unconcerned by the humans stopping to goggle at it. It seems like it is the only Great Blue on the lake but it is often out in the open. Great Egrets and Snowy Egrets come in bunches and are hard to miss, and one can often find a Snowy Egret right at your feet as it forages the edges of the lake.

The Green Heron seems more secretive and has a rather narrow range on the lake (all the iNaturalist observations are in the Northern part of the Lake, though I’ve it a time or two further west).

The little heron flew on a few minutes later, and I settled in to watch a sparrow — before I was graced with a final visit from a White Pelican, flying not too far overhead.

Oakland Autumn Lights Festival

In just a couple days, the Lake Merritt Garden will be opening up for its annual Autumn Lights Festival. Community for Lake Merritt is helping out the Pollinator Posse with a butterfly themed exhibit in the pollinator garden.

We’ll also be having a little UV light critter hunt — no live critters — but some exemplars of cooly lit local California fauna.

The festival is Thu, Fri, and Sat, October 19-21, 6-11pm. Make sure to get tickets in advance, it does sell out. The even is rain or shine.

Freedom to Roam!

2017 - 1 (1)At long last, the 10th street bridge and pedestrian paths underneath are complete. It has been quite some time in the making. The bridge opened to traffic earlier in the year, but the paths opened sometime in early to mid October. It was a nice feeling to be able to bike nearly alway down the channel without crossing a road.

There’s already been a bunch of tagging, but we can hope that the city is maybe planning for a mural or two along those walls. I’m sure Laney college has enough talent to share.

A Cormorant Shift

In my 4 years living in Oakland, I have often stopped to watch and listen to the Cormorants nesting out on the bird islands of Lake Merritt. Their guttural moans, groans, cries — however you might describe them, seem like they are from some other larger beast lurking on the island just at the edge of hearing.

Last week, April 7th, the night after a hard storm — the winds rocked my two story building — I’d done a circuit of the lake curious of what damage there might be and stopped across from the Cormorants, who seemed business as usual.

Except, the groans were much closer, much louder than I’d ever heard them — and I suddenly realized — behind me. I turned around to find a dozen or more cormorants in a tree I’d never noticed them in before. Actively building nests, and had seemingly just started.

Cormorants would fly into the tree carrying a branch, and the one at the tree, would greet the incoming bird with a neck rub, and a groan — perhaps enticement for its partner to keep coming with the twigs and leaves. The groans rose and fell, sometimes in conjunction as the birds flew in an out.

Three days later, Cormorants were still busy building/repairing nests… though the interactions sometimes seemed less than friendly (the birds on the nests sometimes seems to have to wrestle for control of the stick, as if they can’t decide who should have the honor of placing it). It is clearly hard work for the birds to bring the sticks up to the trees, often flying out into the lake and doing a pass before they can get the right angle. But the nests in the new tree seem more or less complete.

I can’t be 100% certain they hadn’t already started nesting there before the storm. If you have any evidence one way or another (a photo from before the 7th), I would love to know.

In any case, it will be interesting to see how successful they might be here in this new tree. I’ve seen raccoons scale that tree before. It will also be a slightly chancy thing for walkers and pedestrians to walk under the tree. It already is a little smellier!
