Note: This is the eighth in a series of occasional blog posts by GGBA member George Peyton about his other half Lani Rumbaoa’s effort to see over 600 bird species in the Lower 48 states in 2015.

Southeast Arizona (SEAZ) is justly famous for harboring a number of Mexican bird species that barely cross the border into that region and are often found nowhere else in the United States. This was to be the last place this year where Lani could add a significant number of new species to her Big Year List. When we started on July 27, Lani’s List was up to 535 for 2015, and I estimated that if she were very lucky, she could add 35 to 40 new species.
We were fortunate that our close birding friend Bob Hirt (Birder Bob) — who had done an exceptional job as Lani’s unofficial guide on the Texas Coast during April — agreed once more to act in that capacity in Southeast Arizona. Bob spent a huge amount of time before the trip researching where to see the maximum number of species in SEAZ, so that each day we had a detailed itinerary with at least four or five different birding stops, each aimed at finding one or two specific Target Species.
Our trip to Southeast Arizona was specifically timed to coincide with the summer monsoon rains that bring a “second spring,” i.e., a second breeding season for many species of birds. The lush green landscape and cooler temperatures brought about by near-daily rains over two to three weeks are in stark contrast to the extremely hot, dry summer climate with temperatures up to 110 degrees in much of the rest of Arizona during that period.
Most people in California have never heard of the SEAZ monsoon rains in late July and early August, but it is often the best time to see the Mexican bird specialties, particularly hummingbirds such as Violet-crowned, White-eared, and Lucifer, as well as Plain-capped Starthroat.

We flew into Phoenix and directed our rented Jeep Cherokee right away to Encanto Park Golf Course, the only place in the U.S. where Rosy-faced Lovebirds can be found. Lani’s sharp eyes picked out a pair within one minute of our arrival, about 100 feet away under a tree.…

Golden Gate Bird Alliance has joined the growing chorus of park users and neighbors urging shutdown of the controversial Chabot Gun Club and shooting range.
In a letter to the East Bay Regional Park District this week, GGBA urged non-renewal of the gun club’s lease because of its danger to wildlife, its disturbance of neighbors and park users, and the very high costs of bringing it into compliance with environmental laws.
“The serious negative environmental consequences, plus the daunting costs associated with extending operation of the Club on District land, significantly outweigh any possible benefit of extending the Club’s lease,” GGBA Executive Director Cindy Margulis wrote in the letter.

Since 1964, the gun club has operated a shooting range with toxic lead ammunition in the watershed of Lake Chabot in Anthony Chabot Regional Park, in the hills between Oakland and Castro Valley.
The East Bay Regional Parks board is scheduled to discuss renewing its lease on November 3rd.
GGBA opposes renewal of the lease for several reasons:

• Lead contamination. Toxic lead levels in the streams flowing from the gun club to Lake Chabot have been found to be more than 14 and 20 times greater than EPA benchmark levels. Lead is fatal if ingested by wildlife – including the 145 species of birds found in Chabot Park. Raptors and vultures are poisoned by eating lead-tainted prey, while other species may be exposed by drinking or bathing in lead-contaminated puddles and water sources. Even Lake Chabot’s nesting Bald Eagles are at risk from lead contamination.

• Noise pollution. Neighbors have complained for years about excessive and disruptive noise from the shooting range. In addition, the sound of gunshots is disturbing to hikers and other park users who come to the park for serenity and peace of mind. Gunfire is all too common and frightening in many Bay Area urban communities; our parks are meant as refuges from that kind of stress.

• Noise impacts on wildlife. Loud noise such as gunshots can harm wildlife as well as humans. At the very least, birds are deterred from using otherwise viable habitat by gunfire. In addition, researchers have documented stress in birds that are flushed by gunfire. Other studies show that birds’ hearing can be permanently damaged by the sound of gunfire.

Editor’s note: On October 6th, Mark Rauzon reported on the SF Birds Yahoo group that he had sighted a Nashville Warbler in downtown San Francisco. But members who viewed his photo pointed out that it was in fact a much more rare Mourning Warbler. Here is Mark’s account of the sighting and what it ended up meaning to him.
By Mark Rauzon
I am sorry I misidentified the San Francisco Mourning Warbler when I found it on Tuesday October 6th. Sorry because a rara avis almost got away and some would miss a lifer and some would be denied a unique county tick. But in hindsight it was the denial of a precognition of death.
I was rushed that day as I had a meeting in Oakland City Hall with our councilmember to try to save the endangered Pallid Manzanita. Since I was at BART and had a few hours before teaching my next class, I jumped on a train and was quickly deposited on the other side of the Bay in the financial district. Two blocks later, I was in Ferry Park. This is a difficult place to bird psychically as homeless addicts, business professionals, and grounds maintenance crews all are in their places. Camera toting, bino laden, I took my place among them. I scanned the towering poplars with the usual sense of how hopeless it is to find a small bird here. But guided by faint chip notes, nearly drowned out by roaring trucks, buses, leaf blowers, sirens, and Ferry Building tower chimes, I saw a Yellow Warbler, a Yellow-rumped Warbler, and a Warbling Vireo, and considered the trip a success. Then I followed a hummingbird into the forest and atop the hill.
I immediately saw something run like a rat into the ground cover. I waited and watched a trembling leaf, then got a glimpse of a yellow bird with a complete eye ring, confirming it wasn’t a MacGillivray’s Warbler. I was sure to see it hopped, not walked, so I eliminated Connecticut Warbler. Because of my lack of familiarity with Mourning Warbler, I was conservative but my heart was pounding as I knew this was something special.

I dug into my backpack for my camera to document this but the battery was dead. I took a cell phone shot, cursed, took another shot through my binos, cursed, and looked closely at the bird as it disappeared into the agapanthus hugging the hilltop.…

We don’t normally write blog posts about field trips… but a trip to Brooks Island is not a normal trip.
Brooks Island Regional Preserve, a 373-acre island off the Richmond shoreline owned by the East Bay Regional Park District, is not usually open to the public. You need to visit as part of a guided kayak or boat tour. The very shallow waters and dramatic tide changes make access tricky. There are only a handful of boat tours each year — and we were fortunate to be able to reserve one for Golden Gate Bird Alliance members and friends this past weekend.
Big thanks to East Bay Parks and Dolphin Charters for making this trip not just possible but delightful!
The bay was uncommonly calm and glassy when we departed from the Berkeley Marina on Dolphin Charters’ comfortable and steady River Dolphin. We passed herons and cormorants at the marina, grebes and gulls on the open bay, and — sadly — both dead and living Common Murres. The murres have been struggling this year, most likely due to warmer ocean waters that reduced their food sources. Many have washed up dead or sick on Northern California beaches. They are birds of the open ocean, not normally found within the waters of San Francisco Bay. So seeing even the live ones here was worrisome.

We circled around Brooks Island’s long breakwater, built originally to protect the port of Richmond. The roots of the island’s name are unknown: It was noted as Brooks Island in the mid-1800s, and before that the Spanish called it Isla de Carmen. At various points it was used for sheep and cattle grazing, oyster farming, and quarrying. Before East Bay Park bought it in 1968, it was operated as a private hunting club for celebrities including Bing Crosby, with game species like pheasant imported for their shooting pleasure.
As we approached the island, we sighted an Osprey devouring a fish on a wooden pier! Also a pair of Surf Scoters, even though it is early in the season for these winter visitors.

Because the water around the island is so shallow, visits need to be planned for high tide.…
