Ocean Microplastics Webinar tonight! | Dr. Victoria Fulfer & Malibu Divers

August 5, 2026

[Posted by Chuck Almdale]

I just discovered this in an Email from Karen Martin*, Chair of the Beach Ecology Coalition (https://BeachEcologyCoalition.org) and Distinguished Professor of BIology Emeritus, Pepperdine University. Anyone ignorant, blasé, interested, affected, angry or sweating blood about the megatons of microplastics in our oceans, wildlife and probably ourselves might want to check it out. It’s tonight! I don’t know if they’ll be making a permanent video. Malibu Divers has webinars first-Wednesday-of-the-month, mostly on topics of interest to divers and other lovers of the sea.

A webinar on ocean microplastics will be live on Wednesday August 5 at 5pm from Malibu Divers.  Dr. Victoria Fulfer, a microplastics scientist with The 5 Gyres Institute, will speak on From Garbage Patch to Groundswell: How Global Microplastics Research Informs Local Action. Dr. Fulfer’s work examines how microplastics travel through watersheds and into the ocean, their impacts on marine ecosystems, and how scientific research is helping communities develop practical solutions.

Loons and other birds: Malibu Lagoon: 26 July 2026

July 30, 2026

I wouldn’t want to wake up with this staring at me.

I could tell the surf was up as soon as I turned onto PCH from Malibu Canyon Road. Not because I could see it, but by the cars filling both sides of the road near the entrance to the lagoon. Only late-arriving surfers pay the parking fee, which can run high if you stay long.

One question we get this time of year is how do we sort out the ducklings, as both Mallards and Gadwall breed at the lagoon. “Figure out who the mother is. She’s usually nearby.” Seriously. I can’t tell them apart until they start looking like adults. Google AI has offered me a lot of advice lately on getting my new computer working, so I inquired, and discovered these useful tips.

In flight, the Gadwall’s neck is slightly thinner and the wings slightly more slender than a Mallard’s.
“The Mallard duckling has tiny webbed feet.”

Good to know.

Ducklings, probably Mallard (Chris Tosdevin 7/26/26)

The Killdeer below is definitely molting, or perhaps beaten up. It may have been born a few months ago. When their breast rings first come in, they’re very messy.

(Chris Tosdevin 7/26/26)

Pied-billed Grebes dive for their food. They are excellent swimmers and divers, partially because their legs are far back on their body. The downside of this structure is that they must avoid walking on land, which they do by nesting on the water among reeds from which they build their floating nests. A pair nested last year in the northern lagoon channel reed bed. If there was a pair there this year, their nest was very well hidden.

The Barn Swallows had a very good year, and the air was filled with them chasing flying insects. There’s a small dead tree near the PCH bridge upon which they love to rest. Easy on – easy off. There are at least eleven pictured below.

The most surprising bird of the trip was a Common Loon in breeding plumage, swimming in the lagoon and diving for fish. It then disappeared for a while, and those arriving late couldn’t find it. Like the grebes, loon’s legs are well back on their bodies and they cannot walk on land, so we figured it must have flown away.

Common Loon (Femi Faminu 7/26/26)

Later we relocated the loon on the eastern end of the southeast island in the channel. It was sitting on the ground. Whenever I see a grebe or loon on the ground I figure there’s a good chance that it’s sick or wounded, as they really don’t like being on land due to their inability to walk. But this loon had appeared active and healthy earlier. Another mystery.

Loons in general are rarely in breeding plumage in Southern California. In late spring, just as they’re leaving for their northern nesting waters, we may see a few that have already molted into their alternate (breeding) plumage. Malibu Lagoon is not a major stopover spot for them, but we can sometimes see skeins of them in the distance passing over the sea.

(Chris Tosdevin 7/26/26)

Below is a screen shot of loonish history at the lagoon. None of the three species are particularly common, and the Common Loon is not the most commonly seen. The Red-throated and Pacific Loons are not here at all in June – August. The Common Loon has previously appeared once in June, and this appearance was the first for July. We hold our trips at month’s end, and by the end of August, they’re a bit more common.

Another uncommon bird was the young Surf Scoter which was resting among a few dabbling ducks on the western island in the channels. Scoters are ocean birds and rarely come into the lagoon. Again, we wondered if it might be ill.

Later it stood up, walked around and showed us the pale belly of youth.

Caspian Terns, named for that well-known Sea, are usually the easiest tern to identify on our beach. They’re the largest, usually have the most black on their crowns, and their blood red bills usually have a dark tip.

Caspian Tern (Kathleen Waldron 7/26/26)

The slimmer bill of the Royal Terns ranges from dull yellow to bright orange, and their crowns don’t remain all-black for long. They tend to be slightly shorter than the Caspian and look a bit less bulky.

Royal Tern (Chris Tosdevin 7/26/26)

The Elegant Tern at 17″ is shorter and smaller than the 20-21″ Royal. Their caps remain darker than does the Royal’s, and the dark eye is nearly always “embedded” in the dark cap, whereas – when not in breeding plumage – the Royal’s eye is usually slightly separated from the cap. The bill color of both species range have the same range of dull yellow to bright orange, but the Royal’s bill is stouter and straighter than the Elegant’s bill. In breeding season the Elegant’s breast often has a slight rosy glow.

This Least Sandpiper seemed exceptionally stripe-breasted.

Egrets and herons have a variety of feeding and fish-luring maneuvers, such as this Great Egret’s water-wiggling. But I think the Black Heron (Egretta ardesiaca) of Southern Africa has them all beat. It pretends to be a short shady umbrella bush growing in the water, and the small fish in the overheated pond come to cool themselves around it’s shaded legs.

Chris Todevin is a whiz not only finding the smallest butterfly in the world (or at least North America), but then photographing it. Come to the lagoon and see if you can find them yourself. Tip: look for dust or leaf particles bouncing in the breeze; some of them are butterflies.

When it’s not breeding season, Heerman’s Gull is nearly always at the lagoon, giving proof that not all gulls are mostly white.

Juvenile Western Gull with a dark face (Chris Tosdevin 7/26/26)

We were mystified for a while by this bird’s face with a dark “mask,” and ID’d it three ways. According to Chris Dean, gull maven at eBird, this mask effect is not uncommon among juvenile Western Gulls.

And finally, a brief story…

Cormorant & Pelican (Ray Juncosa 7/26/26)
Overheard on Malibu Beach
Cormie: It was this big. I had it, I swear, but it got away!
Pete: Yeah, right. I wasn’t born yesterday!

Malibu Lagoon on eBird as of 7-28-26: 9538 lists, 3122 eBirders, 323 species

The 10-year comparison summaries created during the 2012-13 Lagoon Reconfiguration Project period, remain available—despite numerous complaints—on our Lagoon Project Bird Census Page. Very briefly summarized, the results unexpectedly indicate that avian species diversification and numbers improved slightly during the restoration period June’12-June’14. We also have a newly-refurbished slide show of the reconfiguration from just before it started until the recent 13-year celebration.

Many thanks to Marie Barnidge-McIntyre, Femi Faminu, Julie Rush, Chris Tosdevin and others for contributions made to this month’s census counts.

The species list below was re-sequenced as of 12/31/25 to agree with the eBird sequence. If part of the right side of the chart below is hidden, there’s a slider button inconveniently located at the bottom end of the list. The numbers 1-9 left of the species names are keyed to the nine categories of birds at the bottom. Updated lagoon bird check lists can be downloaded here.

Is landfill junk food bad for storks? | The Guardian

July 25, 2026

Health risk fears for storks in Europe over ‘junk food’ from landfill

Rubbish dumps can expose birds to contaminants, raising questions over whether landfill foraging helps or harms

By Vandy Widyalankara, 8 July 2026

From the article:

Prof Aldina Franco, an ecologist at the University of East Anglia (UEA), who was not involved in the research, said the study broke new ground by looking at the effect of contaminants on the storks.

Food found in landfill is like “junk food” for birds, she said. “It’s food that is rotting and it’s poor quality, and probably highly energetic. So, they can get leftover steaks or leftover fish, everything we throw away to landfill sites.”

Franco added that the picture is nuanced: “It is true that it can be damaging for individual storks to eat these types of food that can have contaminants and diseases. But from a population perspective, if you’d have 500 storks going to a landfill site, maybe a few will die from eating these contaminated items, but the majority will actually benefit from having extra food.”

Bird Song & Acoustic Motifs | NPR & NAS

July 24, 2026

[Posted by Chuck Almdale, suggested by Lillian Johnson]

A recent study has found that birds world wide have only eight basic patterns of song, called “acoustic motifs.” Each of the more than 11,000 species of birds have their own special songs, croaks, burps, gurgles, wing-beating, foot-stomping or feather-whistling, but among the songsters in the passerine order, it’s only eight basic types. The NPR show Short Wave has a brief discussion of this study beginning at 7:50 on the recording below (preceded by an interesting discussion of avocado genetics). They play several sample bird songs and there’s a transcript available.

There is a longer article from the National Audubon Society, which also includes song snippets so you can hear the various motifs.

The team analyzed more than 116,000 songs from 3,160 passerine species, the diverse group that includes all songbirds and more than 60 percent of all birdlife. Their analysis revealed the eight “building blocks” that all these birds draw from when they sing: slow, fast, and ultrafast trills; flat, slow-modulated, and fast-modulated whistles; harmonic stacks; and chaotic notes. The Eastern Wood-Pewee’s “pee-ah-wee,” for example, illustrates the slow-modulated whistle, which sounds like a smooth, plaintive curve of sound, with just a gradual pitch change. The Bohemian Waxwing, meanwhile, offers a great case of the ultrafast trill: high-pitched, rapid-fire pulses that blur together.

Many years ago, there were Birding By Ear audio tapes available to help in learning bird songs, Eastern and Western versions. One point that stuck in my mind and remains useful is that both American Robin and Black-headed Grosbeak had slow rolling musical songs of similar pitch, but the robin’s was slightly faster.

Read and listen. I guarantee you’ll never hear birds the same way again.


The original paper is The global biogeography of passerine songs by Quentin Bacquelé, Jean-Yves Barnagaud, Cyrille Violle, Frédéric Theunissen and Nicolas Mathevon, published by Science, 23 Jul 2026, Vol 393, Issue 68. It’s behind the usual paywall, but if you have access, here it is.

Editor’s summary

Birds sing to attract mates and ward off rivals. The form of these songs can vary from single, repeated notes to complex melodies. Bacquelé et al. explored the relationships among song, environment, and latitude from birds across the world (see the Perspective by Briefer). They found that in regions where forests are thick, and thus sound transmission is slower, bird songs are simpler and more effective for transmission across vegetation-impeded landscapes. By contrast, in temperate regions, where sound is less impeded and sexual selection is especially strong due to seasonal limitations, birdsong is much more complex, likely being a better indicator of singer condition. —Sacha Vignieri

Abstract

Although bird songs are classic models for understanding the evolution of vocal communication, their global diversity has long made the development of a unifying framework challenging. By analyzing the acoustic architecture of songs from more than 3000 passerine species worldwide, we show that this acoustic space can be structured around eight elemental motifs. The differential use of these motifs is driven by a combination of species’ biological traits (social organization, morphology, and mating system) and the physics of sound propagation. In tropical rainforests, environmental filtering for transmission efficiency favors structurally simple motifs, such as flat whistles. Conversely, in temperate regions, where high population densities facilitate close-range communication and short breeding seasons intensify sexual selection, the balance shifts toward complex, information-rich motifs, such as ultrafast trills, despite their susceptibility to acoustic degradation. Ultimately, the global geography of birdsong reflects a spatially varying equilibrium between physical environmental constraints and the biological drive for complex communication.

Pacific Coast Highway: There are still reportedly lane closures as fire recovery work continues.

  • 25 MPH between Temescal Canyon Rd. & Sunset Blvd.
  • 35 MPH between Sunset Blvd & Carbon Beach Terrace
  • Watch for workers & vehicles. (Active work on Sunday morning at 8am? Take a picture.)

Special Attractions: Like dinosaurs? Want to see a dinosaur? Our feathered dinosaurs have no teeth and won’t bother you, although if you happen to have a small snail or fly in your pocket, they might be interested.

Some of the great birds we’ve had in July are:
Gadwall, Pied-billed and Eared Grebe, Anna’s & Allen’s Hummingbirds, Snowy Plover, Whimbrel, Wilson’s Phalarope, Spotted Sandpiper, Wandering Tattler, Willet, Ruddy & Black Turnstones, Red Knot, Surfbird, Western Sandpiper, Heermann’s & Western Gulls, Black Skimmer, Least, Caspian, Royal & Elegant Terns, Reddish Egret, Great Blue Heron, Brown Pelican, Red-shouldered Hawk, Belted Kingfisher, Oak Titmouse, Rough-winged, Barn and Cliff Swallows, Wrentit, Northern Mockingbird, American Robin, House Finch, American Goldfinch, Savannah & Song Sparrow, California Towhee, Hooded Oriole, Red-winged Blackbird, Common Yellowthroat.

Adult Walk 8:30 a.m., 4th Sunday of every month. Adults, teens and children you deem mature enough to be with adults. Beginners and experienced, 2-3 hours, meeting at the metal-shaded viewing area between parking lot and channel. Species range from 35 in June to 60-75 during migrations and winter.  We move slowly and check everything as we move along. When lagoon outlet is closed we may continue east around the lagoon to Adamson House. We put out special effort to make our monthly Malibu Lagoon walks attractive to first-time and beginning birdwatchers. So please, if you are at all worried about coming on a trip and embarrassing yourself because of all the experts, we remember our first trips too. Someone showed us the birds; now it’s our turn. Bring your birding questions.

Children and Parents Walk, 10:00 a.m., 4th Sunday of every month: One hour session, meeting at the metal-shaded viewing area between parking lot and channel. We start at 10:00 for a shorter walk and to allow time for families to get it together on a sleepy Sunday morning. Our leaders are experienced with kids so please bring them to the beach! We have an ample supply of binoculars that children can use without striking terror into their parents. We want to see families enjoying nature. (If you have a Scout Troop or other group of more than seven people, you must call Jean (213-522-0062) to make sure we have enough binoculars, docents and sand.) It’s a good idea to call Jean anyway so she knows to expect you. If you’re late, they’re probably heading towards the beach.

Directions: Malibu Lagoon – street address is 3999 Cross Creek Rd. – is at the stoplighted intersection of Pacific Coast Highway (PCH) and Cross Creek Road, just west of Malibu Pier and the bridge, 15 miles west of Santa Monica via PCH. Turn towards the ocean at the stoplight, opposite the Shell station. We gather in the metal-shaded pavilion area near the parking lot. Look around for people wearing binoculars and hats. Do NOT go to 23200 PCH, the address for Adamson House, east of Malibu Creek bridge, and a 5-10 minute walk away, plus 20-40 minutes to get into their surfer-packed parking lot.

Parking: Parking machine in the lagoon lot near our meeting area: 1 hr $3; 2 hrs $6; 3 hrs $9, all day $12 ($11 seniors); credit cards accepted. Annual passes accepted. You may also park (read the signs carefully) either along PCH west of Cross Creek Road, on Cross Creek Road, or on Civic Center Way north (inland) of the shopping center.  Lagoon parking in shopping center lots is not permitted.

This gull won first prize. Now what?
