L.A.’s Griffith Park Mountain Lion with Miguel Ordeñana | Natural History Museum’s Curiosity Show

December 30, 2017

In Los Angeles, our most heroic urban nature story is the journey of P-22, a male mountain lion who traveled across the city and two busy freeways to get to Griffith Park. P-22 was first observed in the park by our citizen science coordinator Miguel Ordenana. Miguel leads us through the exhibit and shows what P-22 had to conquer to make it all the way across town to reach his new home.

SMBAS field class in bird ID

December 27, 2017

SMBAS field class in bird ID

 SMBAS will offer a short field course in bird identification in the spring of 2018.  The course is intended to help new or novice birders improve their birding skills while learning how to identify some of the species commonly found in the Los Angeles basin.

This year, the course will consist of 6 Saturday morning sessions, each of which will be held in a local park or natural area.  Sessions will begin in late February.

Enrollment is limited to 8.  A donation of $60 per SMBAS member or $90 per non-member will be requested.

For more information, send an e-mail to SMBAudubon[AT]gmail.com  and put “Bird Class” in the subject line.

Winter’s Icy Chill Strikes Malibu Lagoon, 24 December, 2017

December 27, 2017

The elegant Pintail used to be more common in the late 1970’s. (R. Ehler 12-24-17)

A surprising number of birders appeared, considering that it was Christmas Eve Day, and it was chilly. (57°F or 14°C is considered chilly around here. This blog’s title is tongue-in-cheek). We had a good assortment of birds, although all did not appear at the same time nor did everyone see all of them. The Merlin, for example. The first I heard about it was when I was asked: “Wow! Didja see that Merlin! What a show!” Well…no I didn’t, but thanks for asking. Once gone, apparently, gone forever.

Congener Phoebes: Say’s and Black, typically over-winter at the lagoon
(R. Ehler 12-24-17)

We had some people new to birding, and some birders new to the lagoon. Thus, plenty of questions and plenty of new birds for some of us. A cluster of (three, I think) birders had just finished a beginning birder’s course with Pasadena Audubon, and the gulls and shorebirds seemed to be new to them. As a reminder to our readers, our chapter has a beginning birding class beginning soon, but it might already be full.

House Finches seed-eating in beach brush (R. Juncosa 12-24-17)

Some ducks showed up, finally, so I guess the weather up north became a bit more wintery. I’ve recently read that some West Coast sea counts (stand on a seaside high point and count birds flying by) of ducks were down about ninety percent from prior years. That sounded about right to me. But today we had eight species of duck, two of grebe and two of loon. Not large numbers of any particular species, but good diversity.

Snowy Plovers a-plenty on the beach. Thirty-five of them, scattered widely through the washed-up detritus and footprint-hollows landside of the beach berm, including banded birds AA:BG and RR:BB, the latter bird spotted by Chris Lord.

Double-crested Cormorants in the lagoon, Western Gull preening (R. Juncosa 12-24-17)

Gulls were numerous. Most were California Gull, which is to be expected, but we also had one Bonaparte’s, one Mew (reported to me), Two Heermann’s, one Herring and two Glaucous-winged. Royal Tern was the only tern species. Forster’s and Caspian Terns must be around, somewhere, but the Elegants have fled to Baja for the winter. The larger shorebirds – Willet, Whimbrel, Marbled Godwit – have dwindled in numbers by about 70% since last month.

Whimbrel pokes around the beach (R. Juncosa 12-24-17)

One or two of the heavy-billed Common Loons were swimming around in the now-shallow lagoon waters. Shallow because the beach was breached during a recent high-tide, most of the water ran out, the water level dropped a couple of feet (estimated) and the water surface area is probably half of what it was a month ago.

Common Loon toolin’ down the lagoon (R. Juncosa 12-24-17)

Speaking of water, the current drought and low humidity is really affecting plants and trees everywhere, causing them to dry out and encouraging all our recent wildfires. The “Thomas” fire had become the largest wildfire in recorded California history – over 280,000 acres (450 square miles), and many homes gone. Many of the bushes look extremely brown and wilted. The tree by the picnic area died and fell over. Someone dragged it out of the path. Downtown Los Angeles had 0.11 inches of rain for Nov-Dec, 94% below normal.

Bewick’s Wren – pronounce it “Buick” or he gets upset – are usually up in the chaparral (R. Ehler 12-24-17)

Western Meadowlark on his rainbird perch (R. Ehler 12-24-17)

On my way out I met a birder, who asked if I though the bird he was looking at was a Cooper’s Hawk. It was on the ground on the small island near our gathering spot. I do not expect to find Cooper’s Hawks on the ground, sitting quietly, doing nothing. I’ve seen them on the ground while eating some hapless bird or rodent, such as the one disassembling and scarfing a rat in my backyard one recent winter. But we agreed that it was a juvenile Cooper’s. Sometimes juvenile raptors haven’t quite figured out how to catch prey. I’ve seen juvenile Red-tailed Hawks chase squirrels by hopping around on the ground, and a juvenile Great Black Hawk in the Peruvian Amazon trying – completely unsuccessfully – to grab any one of over a dozen Hoatzins resting in a fallen riverside tree by jumping ungainly from limb to limb.

Nick, the birder, turned out to be an Ornithology student at San Diego State, visiting locally for Christmas. While I was making my best attempt to tell him how to get to the Ballona Creek jetties to see rocky shorebirds, we spotted a small falcon diving on the Cooper’s Hawk. It was a Kestrel. I haven’t seen a kestrel at the lagoon since 9/25/16, fifteen months ago. Then, to top even that, while talking to Lu Plauzoles in the parking lot about his waste fishing line collection efforts on the Malibu Pier, he spotted a Nuttall’s Woodpecker female whacking away in a nearby tree. This is only the seventh Nuttall’s we’ve spotted at the lagoon in almost forty years; the last one was in October 2015.

Blue-gray Gnatcatcher, another species usually up in the chaparral (R. Juncosa 12-24-17)

Apropos this unusual woodpecker coastal sighting, Lu commented that he had heard a conjecture from knowledgeable and local birder Dick Norton that the drought, dying trees and lack of invertebrate prey had forced many birds to flee local hills and chaparral and seek food elsewhere. Lu thought this might be why the woodpecker, the Blue-gray Gnatcatchers and Bewick’s Wrens were around the lagoon in larger than usual numbers this year. He may be right.

On the other hand, Chris Lord – SMBAS member, regular birder at Topanga Canyon and monthly bird census participant at Ballona Freshwater Marsh – had this comment after reading my original posting.

Concerning your Malibu Lagoon write-up and comment on Blue-gray Gnatcatchers [BGGN], my local experience is that many BGGN winter nearer sea level and are absent in winter up in Topanga State Park [TSP], at least in my counting area; then they reappear there in TSP for spring and summer. I have never learned if these are mostly local birds in vertical migration or not. At Ballona Freshwater Marsh (BFM) we count roughly 5 to 10 BGGN per monthly winter count, and I get 3 to 14 BGGN per Topanga State Park count, starting mid-March and peaking in mid-August. I don’t know why we don’t see more wintering at the Lagoon. Maybe there are more at Legacy Park [an inland park a short distance from the lagoon]? They sure like BFM, maybe for its larger habitat area.

Another mystery of nature as yet unsolved. [Sounds like a future PhD thesis to me.] Whatever is really going on, let’s hope there’s some rain in our near future.

A young White-crowned Sparrow (R. Ehler 12-24-17)

Birds new for the season were: Surf Scoter, Bufflehead, Bonaparte’s Gull, Herring & Glaucous-winged Gull, Pacific & Common Loons, Osprey, Cooper’s Hawk, Nuttall’s Woodpecker, American Kestrel, Merlin, Barn Swallow, California Towhee.

DNA Doesn’t Look Like What You Think! | PBS Science Video

They  used #badDNA once in this video. Can you find it?

Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they’re good models for understanding how DNA works, but inside of real cells, it’s a whole lot more interesting. Learn why we can’t look directly at DNA, and find out how DNA is actually packed inside cells.

A Major Policy Action Against Birds

December 25, 2017
by

In a Christmas gift to industry and business, Daniel Jorjani, counsel to the Department of Interior, has issued a legal opinion that guts the Migratory Bird Treaty Act, (MBTA), which is a law about to celebrate 100 years of bird protection.

Click to access m-37050.pdf

The MBTA is a very broad law, sparingly enforced by the US Fish and Wildlife Service, part of the Department of Interior. Those of us who are involved in trying to protect birds from the multiple threats of human land use and industry, know the law is very rarely applied and prosecutorial discretion is a major brake on its potential bite. I have spoken to former employees of the USFWS who left the agency because of its prosecutorial timidity. The fact is the MBTA is very rarely invoked in prosecution.
However, in his long, eminent lifelong legal career*, Mr. Jorjani has become the brave defender of every cat owner and auto driver in the United States. By arguing that the MBTA makes every pet owner and driver a potential criminal, subject to the whims of prosecutors and officials, he has decided to strictly limit the implementation of the law to only “direct and affirmative purposeful actions that reduce migratory birds, their eggs, or their nests, by killing or capturing, to human control.”
This means he has effectively gutted the MBTA. We know how difficult it is to prove intent, i.e. “affirmative, purposeful action.” Every builder, developer, bulldozer operator and drone-flyer must be cheering today. In order to avoid any penalty for killing birds, mowing their grassland nests, or otherwise harming or harrassing them, all the people have to do is say “I didn’t mean to. I was doing something else.” In a strange twist, the dog owner whose pet starts chasing an endangered or threatened species might also use the same excuse. I fear for our Snowy Plovers. The concept of “incidental take” has been taken off the books by administrative action. The current administration has shown its disregard for wildlife.
