Hi folks,
Bob and I spent a couple of hours this morning at Las Cienegas in Sonoita. We weren't expecting a huge variety of birds, but we ended up with 21 total.
By sheer numbers, Vesper Sparrow and Cassin's Kingbird were number one and two. I'm sure we missed a few sparrows, but they were really hard to get good looks when they dove into the grass. We were able to ID a Lark Sparrow, White-crowned Sparrow, and a Rufous-crowned Sparrow.
For raptors, we saw male and female Northern Harriers, Red-tailed Hawks, and a couple of American Kestrels.
Flycatchers included Say's Phoebe, Ash-throated Flycatcher, and Phainopepla.
We did see a single Loggerhead Shrike on a wire.
We didn't stop at Cottonwood Tanks due to a large number of cattle nearby and LOTS of mud.

I had young person to deliver to school in the midst of the Monday morning heavy downpour in central Tucson, but grabbed my binoculars just in case, as it looked like the rain would soon pass. And it did, so I took a walk around Himmel Park about 8:00 and among the usual preening and pecking suspects I also spotted a single black and white warbler in the oleanders and mesquites on the south side at Sawtelle St. Had a great view for awhile. Also my own FOS white crowned sparrows, which is what I set out hoping to see.

This morning, five local birders attended the birding walk at the Sierra Vista
Environmental Operations Park (EOP). We walked the dikes, and we saw 62
species of birds.
Expecting a thunderstorm later in the walk from the wake of Hurricane
Precilla, we came prepared with raincoats and umbrellas. It did not happen. We
had a pleasant cloudy walk with the temps in the mid-60s. Nice.
Ducks were the theme of the day. We spotted our first pochards of the year;
Lesser Scaup and Ring-necked Ducks. Some will likely be around through the
winter at the EOP. The American Widgeons are a different story. They arrive
about now in very large numbers, 125 today! This large flock will increase and
remain through the fall, but strangely mostly disappear in January at the EOP.
We saw twelve duck species in all today, including two still black-downy
rubber duckies, I mean Ruddy Ducklings diving near their mother. Also somewhat
strange was that we saw only three Mexican Ducks today. Usually, the post-
breeding flocks at the EOP are very large through the winter. Where did they
go?
The bird of the day was a single Lawrence’s Goldfinch calling a bell-like
“TEE-lee” as it flew overhead. We are hoping that it might be an irruptive
year for these little darlings, but there does not appear to be much food for
finches this year. See them while you can.
Five transient Vaux’s Swifts were another nice sighting for the day.
Birding walks behind the locked gates of the Sierra Vista EOP occur every
Sunday morning. For the months of October and November, the walks start at
7:00am. Meet early at the EOP Bird Viewing Platform to sign up with the guide.
Late arrivals will not have access behind the locked gates. Scopes are useful.
A hat and water are highly recommended.
The EOP is located just east (~ 3 miles) from Sierra Vista on AZ Hwy 90. Look
for the Brua Animal Care Center and the Wildlife Viewing signs on the
northside of AZ Hwy 90. Turn left (north) and proceed to the bird viewing
platform. Note that Google Maps may direct you to the wrong entrance.
The next EOP Birding Walk is on Sunday, 19 October, at 7:00 am.

Yesterday morning 6 locals joined the Friends of the San Pedro River birding walk. We walked the trails around the San Pedro House and found 30 species. 30 species is very low for this time of the year. Bird numbers were also very low-we had long stretches with no birds.
We did have a few good birds. One of the highlights was a Common Black Hawk soaring right above us. Everyone in the group got excellent views of this hawk. We had one Crissal Thrasher in Garden Wash. As is often the case we never saw this thrasher. However, it was singing incessantly. First the chewy-chewy call then extended bouts of quiet soft singing. Very enjoyable to listen to! Gray Hawks are still around and we heard one calling from the river area.
The only new bird for our walks this fall season was Lincoln’s Sparrow. Overall sparrow numbers were low. We did have 3 wren species-Marsh Wren, Bewick’s Wren and Northern House Wren. Flycatcher species were low with only Black Phoebes and Cassin’s Kingbird being seen.
The Friends of the San Pedro River lead birding walks the second and fourth Wednesday of the month. The walks start at 7:00 am from the San Pedro House located south of Highway 90 just west of the San Pedro River. The walks last about three hours. Bring your own binoculars, a hat and water.

Hi, birders,
A very quiet morning for the 9 folks who walked the Sierra Vista EOP dikes,
finding a mere 53 species. This is quite a drop compared to the 84 species
noted last week. All were disappointed that no Least Bittern was found,
although it was a good morning for the rail family. Five Virginia Rails
were calling, outnumbered by 18 calling Soras, one of which ventured far
enough out of the cattails for us to see its bright yellow beak. One Com.
Gallinule put in a brief appearance, again outnumbered by its cousins, 32
Am. Coots.
In the raptor line there were the expected Turkey Vultures and Red-tailed
Hawks, enhanced by one each of Sharp-shinned Hawk, Cooper's Hawk, and N.
Harrier, plus several Am. Kestrels. Indicative of the dearth of passerines
was the low count of 15 Barn Swallows, with no other swallows at all.
Bird walks behind the locked gates of the Sierra Vista EOP occur every
Sunday morning. For the autumn months (September-November) walks start
promptly at *7:00 a.m.* Arrive early at the EOP Bird Viewing Platform to
sign in with the guide--group size is limited to fifteen. Late arrivals
will not have access behind the locked gates. Scopes are useful. Bring a
hat and water--there is no shade nor any amenities on the walk route. There

Greetings Birders,
This report covers last week, starting with a wonderful cool morning at Mittry Lake on Monday, 29 Sep 2025. At Betty's Kitchen one of my first birds was a BROWN PELICAN, a bird I'd been searching for all year. A CLARK'S GREBE with a baby nestled on its back was neat. A RED-SHOULDERED HAWK was an unexpected find. A late BELL'S VIREO called, as well as both SORA and VIRGINIA'S RAIL. Farther north, a BLACK RAIL called as I was exiting my vehicle. In the Dome Valley I found 12 species of shorebirds, including RED-NECKED PHALAROPES, and BAIRD'S & PECTORAL SANDPIPERS. By morning's end I'd seen or heard 83 species.
On Tuesday I started at Spot Road Farm. There I was pleased to find 2 PRAIRIE FALCONS, CASSIN'S VIREO, BENDIRE'S THRASHER, 4 LAWRENCE'S GOLDFINCHES, and a PYRRHULOXIA. At Paloma Ranch I had a good count of 23 BLACK-CROWNED NIGHT HERONS and my first TOWNSEND'S WARBLER of the season. I ended my day at Willcox, where I had a flock of 16 SCALED QUAIL, a handsome SANDHILL CRANE, SWAINSON'S HAWK, and the usual complement of shorebirds.
Wednesday morning I drove through Pinery Canyon on my way to Portal. My primary target for this trip was American Goshawk. Most of the drive was without sighings or song, but a few areas with excellent bird parties made for some excitement. It was my best morning ever for MEXICAN CHICKADEES, and I counted 10 of them. Some of the other good birds were a NORTHERN PYGMY-OWL, a DUSKY FLYCATCHER, and a HEPATIC TANAGER. At the Southwestern Research Station I had a fine showing of hummingbirds, including a handsome male BLUE-THROATED MOUNTAIN-GEM. At Cave Creek Ranch it was fun watching a pair of RED-NAPED SAPSUCKERS. At Jasper's place there was still a visiting SCOTT'S ORIOLE. The desert around Willow Tank was abloom with beautiful yellow plains zinnias and the tank itself was well-watered. I watched a SORA for a while, but unfortunately there were only a handful of active birds there.
Early Thursday morning I added a few new trip birds around Portal, including BAND-TAILED PIGEON, CEDAR WAXWING, and ARIZONA WOODPECKER. Afterwards, I headed west to Ash Canyon Bird Sanctuary. I heard a GRAY HAWK, and then a few minutes later witnessed a COOPER'S HAWK in hot pursuit of an ACORN WOODPECKER. The woodpecker was squealing and making hairpin turns, going up, down, and around the trees. It looked like the hawk caught the tip of a tail feather, and then they were out of sight. At Ramsey Canyon I watched a few RIVOLI'S HUMMINGBIRDS coming in to drink sugar water at the feeders. A pair of CASSIN'S VIREOS gobbled up insects in a large maple. I was able to watch and photograph one of them thrash a caterpillar to death. My final stop for the afternoon was the San Pedro House, where the butterflies far outnumbered the birds. It was fun listening to a COMMON RAVEN making odd vocalizations.
On my last day, Friday, 3 Oct, I started at the Paton Center for Hummingbirds. Most of the hummers were ANNA'S and BLACK-CHINNED, but I did spot the local star, the VIOLET-CROWNED HUMMINGBIRD. A SUMMER TANAGER was nice. Box Canyon was really quiet, with just a few birds noted. As always, Santa Rita Lodge had a number of species, the best of which was a CEDAR WAXWING and a HERMIT THRUSH eating the pyracantha berries. Stops at the Gila Bend Sewage Ponds and Spot Road Farm didn't yield anything special.
I had missed the American Goshawk, but it was still a fine adventure, and I spotted 162 species over the four days. And the Brown Pelican on Monday morning brings my AZ Big Year total up to 385. eBird reports with some photos among them:https://url.usb.m.mimecastprotect.com/s/l-6yCM7nRPIz76lgxhwfku8Ma5v?<domain...> - Betty's Kitchenhttps://url.usb.m.mimecastprotect.com/s/zc7DCN7oVgIjzMRAVS4hguyOqH1?<domain...> - Mittry Lakehttps://url.usb.m.mimecastprotect.com/s/3Zh0COJpWjfvM2GJ5skiyuGWb8P?<domain...> - Spot Road Farmhttps://url.usb.m.mimecastprotect.com/s/pyAECP6q0kC3P5lOvFjsvuxomDC?<domain...> - Lake Cochisehttps://url.usb.m.mimecastprotect.com/s/KNl6CQArYlfoYNx8BsrtyuGUzZA?<domain...> - Pinery Canyonhttps://url.usb.m.mimecastprotect.com/s/TUFoCR8vZmt5xgVJnFouYu1muCz?<domain...> - SW Research Stationhttps://url.usb.m.mimecastprotect.com/s/HKrhCVJz4qfgYPv70sWCKuEY9j_?<domain...> - Willow Tankshttps://url.usb.m.mimecastprotect.com/s/Qt0aCWWA5rTDVyk2zTLFruoh2pT?<domain...> - Ramsey Canyon

Hi, birders,
Seven locals walked the Sierra Vista EOP dikes this morning, finding fall
migration underway, albeit in small numbers of individuals, but in a wide
diversity of species, noting 84 species by the end of the trip.
The best finds were: a flyover Dickcissel, giving its funny, flat "splatt"
call; a Pectoral Sandpiper, a wader we only see in the fall migration; and
brief look at a Least Bittern. The Dickcissel was the 6th record for the
EOP Sunday walks, occurring in the one-month window of late August to late
September when they move through this area. The Pectoral Sandpiper was part
of a small group of waders attracted to the temporary rain pools created by
the heavy rains this past week. The other waders were Baird's, Least, and
Western Sandpipers among the expected Killdeer.
It is almost exactly a year (22 Sep 2024, to be precise) since we had a
Least Bittern at the EOP. Today's bird was seen briefly as it scrambled
clumsily up the cattails and disappeared into the thick vegetation, giving
us side views of its yellow dagger bill, buffy face and neck, and streaked
chest and flank. Early arriving birders to the overlook platform had fine
views of a Merlin, perched and in flight. Small numbers of 8 different
species of sparrow added diversity--perhaps a sign of winter sparrows to
come.
Bird walks behind the locked gates of the Sierra Vista EOP occur every
Sunday morning. For the autumn months (September-November) walks start
promptly at *7:00 a.m.* Arrive early at the EOP Bird Viewing Platform to

Greetings Birders,
Friday (26 Sep) brought a fine change in temperature to Yuma County--fall had arrived! At the Solar Pond close to Wellton a number of sandpipers had arrived to feast of the little flies. Five PECTORAL SANDPIPERS were the most I'd seen to date. A DUNLIN was a first for the season. A flock of RED-NECKED PHALAROPES was nice to see. I spotted a juvenile SABINE'S GULL across the pond, but unfortunately it flew off before I got to it. A NEOTROPIC CORMORANT joined the DOUBLE-CRESTED CORMORANT regulars. A BLACK TERN was unexpected.
As I drove to my next destination I noticed a gull in a flooded area next to the road--it was the juvenile SABINE'S GULL! It was right next to the road and unperturbed by my presence, so I got excellent photos.
At the 6th Ave Drain the shorebird extravaganza continued with 11 species. Four more PECTORALS were joined by LEAST &GREATER YELLOWLEGS, dowitchers, a BAIRD'S SANDPIPER, two SOLITARY SANDPIPERS, and numerous LEASTS and WESTERNS.
Today (27 Sep) I greeted the dawn at Spot Road Farm. Sparrows are now numerous, and a VAUX'S SWIFT made a quick fly-by. There were still a number of flycatchers--I found 7 species. I spotted a PYRRHULOXIA, and wondered if they bred again this year. At a small pond along the eastern edge of the farm, a small yellowish bird with black streaks on its flanks caught my eye. It even stuck around long enough for me to get photos--a lovely MAGNOLIA WARBLER. I had high hopes of getting lots of rare shorebirds at the Solar Pond and the Dome Valley Drain, but an unexpected gully-washer of a thunderstorm altered my plans. After seeing almost nothing through the rain at the Solar Pond, and with the dirt roads getting muddier and muddier, I headed on home.
The Magnolia Warbler brings my AZ Big Year total up to 384. eBird reports with some photos among them:https://url.usb.m.mimecastprotect.com/s/vqXzC0Aj5NfmZ5YkPFwf4t9cN_V?<domain...>

Northing about Arthur Pack Regional Park’s habitat corresponds to that of an Acorn Woodpecker. None the less, there was one foraging about a couple dead mesquites in a wash near the maintenance buildings. APRPark #251 on the eBird Hotspot tally. It cooperated and posed for a few decent photos. When first spotted, two Gila’s were harassing it…. So finger’s crossed that it would weather that storm…. Which it did.
After 8-9 days since at the Purple Martins migrated, a couple transients stopped for drinks, alerting with their fabulous vocalizations.
An Orange-crowned Warbler was the only one seen today.
Brewer’s and White-crowned Sparrows have arrived.
A Western Flycatcher and a Say’s Phoebe posed. A Black Phoebe didn’t.
One Western Diamondback Rattlesnake, five coyotes.
Two days ago at Arthur Pack, I observed a Desert Iguana, which is only the second time I have seen one in the Tucson area. ( The other one was at El Rio in Marana) Range maps put this species at its eastern edge.
The Crooked Tree Golf Course will be closed for annual winter seeding, starting on Monday 9/29- running through Oct 17th. Bird watchers need to avoid the seeded areas of fairways, tee boxes, greens and green fringes.
Anyone walking the course should be aware that the watering system will run frequently. In the past they ran for 4-6 minutes every two hours. They sequence around the course. Some sprinkler heads are located in the rough…. And I can vouch for the surprise that can result.

After seeing the gull yesterday, I was looking up information about it. One guide said that Sabine's have black legs. My photos and the photos from others at Danny Lopez show Oranges feet. Is this because the bird is immature?

Date: 9/24/25 2:41 pm From: dpsiminski (via aznmbirds Mailing List) <aznmbirds...> Subject: [AZNMbirds] San Pedro River Birding Walk
This morning, nine birders participated in The Friends of the San Pedro
River’s Birding Walk from the San Pedro House. We birded a loop south of the
San Pedro House within the San Pedro Riparian National Conservation Area
(SPRNCA). We saw 50 species of birds. The river was flowing very high today
and the River Trail near markers 6 and 7 had flooded and it was very muddy in
that area.
Our Bird-of-the-Day was the Yellow-billed Cuckoo. Besides being a Federally
Threatened population of the Yellow-billed Cuckoo, a life-bird for some
participants, and that it is just a very cool bird, it is probably the last
time we will see one this year. Cuckoos arrive late on the San Pedro River,
about mid-June, breed very fast, and then are mostly gone by mid-September.
One of the two that we saw today was seen by all the participants as it sat
calmly preening in an Arizona Walnut tree. The other was a fleeting glimpse of
a long, boldly spotted undertail as it flew and then disappeared into the
foliage of a Fremont Cottonwood. Another probable EOS (End-of Season) bird
was a single, Yellow-breasted Chat. Back in July, we saw and heard over thirty
during a single birding walk.
Some FOS (First-of-Season) birds for the San Pedro River birding walks were
two Cassin’s Vireos, a few Brewers Sparrows and White-crowned Sparrows.
The most abundant bird of the day was the Green-tailed Towhee. We detected 19.
(!) In the early fall in recent years, they have seemed to migrate through the
SPRNCA in great abundance and then for the winter months become just a regular
common winter resident.
The Friends of the San Pedro River leads birding walks on the second and
fourth Wednesday of each month. For the months of October and November, the
walks leave at 7:00a from the BLM’s San Pedro House south of State Route 90
just west of the San Pedro River. We walk about 4km, and we are out for about
three and one-half hours. Bring your own binoculars, a hat and water.
The next San Pedro River birding walk is on Wednesday, 8 October, at 7:00a.
See you there.

Date: 9/21/25 1:11 pm From: dpsiminski (via aznmbirds Mailing List) <aznmbirds...> Subject: [AZNMbirds] Sierra Vista EOP Sunday Birding Walk
This morning, ten local birders attended the birding walk at the Sierra Vista
Environmental Operations Park (EOP). We walked the dikes, and we saw 76
species of birds.
Today, the day before astronomical fall (autumn equinox), provided us with a
few firsts for the new meteorological fall season (September through
November). The most spectacular was a Merlin that put on a show for us by
passing fast and low just above the cattails. It was presumably hoping to
panic a small bird into doomed flight in front of this speedy little bird
predator. It took several swipes with no luck and then flew to the north. With
the sun low on our backs, all the attendees had great views.
We also had our first Virginia Rail of the season. The Soras had arrived
several weeks ago and were calling loudly from the cattail impoundments,
eleven in all. We had a spectacular view of the Virginia Rail within a meter
of a Sora. We also saw our first Northern Harrier of the season, an apparent
female. Four Swainson’s Hawks soaring together indicated to us that Swainson’s
Hawks are now on their long migration to the pampas of Argentina and will soon
be gone from the EOP. Que lastima.
The breeding behavior highlight of the day was an adult Pied-billed Grebe
feeding a stripe-headed juvenile with a mosquito fish or maybe it was a
tadpole. In year’s past, we have also seen late season breeding of grebes at
the EOP.
Two other standouts for the day were an immature Ring-billed Gull and a Lesser
Yellowlegs.
Birding walks behind the locked gates of the Sierra Vista EOP occur every
Sunday morning. For the months of September, October and November, the walks
start at 7:00am. Meet early at the EOP Bird Viewing Platform to sign up with
the guide. Late arrivals will not have access behind the locked gates. Scopes
are useful. A hat and water are highly recommended.
The EOP is located just east (~ 3 miles) from Sierra Vista on AZ Hwy 90. Look
for the Brua Animal Care Center and the Wildlife Viewing signs on the
northside of AZ Hwy 90. Turn left (north) and proceed to the bird viewing
platform. Note that Google Maps may direct you to the wrong entrance.
The next EOP Birding Walk is on Sunday, 28 September, at 7:00 am.
