Lynch Canyon raptor tours Nov, Dec, Jan



Bird of Prey season is back!

Join Larry Broderick for the 2021- 2022 season at Lynch Canyon and Rush Ranch!

Each year from fall through late winter, raptor expert Larry Broderick of West County Hawkwatch leads weekend hikes and workshops so people can learn about the birds of prey that call the Solano Land Trust properties their home. 

During this viewing season, bring your binoculars and join a group to see the magnificent bids that rely on our protected agricultural open spaces for habitat. Birders of all levels of experience are welcome.

Dedicated to Ken Poerner

By request, Larry Broderick would like to dedicate this year’s Bird of Prey season in honor of our dear friend Ken Poerner, whose tireless dedication to conservation touched every aspect of Solano Land Trust’s work.  Ken passed in early June of this year after a ten-year battle with cancer.  It was Ken who first introduced the Solano Land Trust to Larry, and Larry’s expertise and passion have been an invaluable asset to the land trust and the community we serve for many years.

Upcoming Hike Dates:

Registration for hikes are required.  Please click the links of the dates below to register.

The hike fee is $10 per person. 

Parking at Lynch Canyon is $8.00 during peak season (April – September) and $6.00 during the off season (October – March)

Broad-winged Hawks on the West Coast migration 9-26-2021.... Jenner Headlands Preserve Raptor Migration Hike ~ 10am to 2pm

9.26.2021 Jenner Headlands Preserve
6 Broad-winged Hawks comprised of;
2 Adult light morphs, 
1 Adult dark morph, 
3 Juveniles
(see photo references below)

So WE did a thing yesterday.. 9-26-2021....
During a TWC Raptor Migration Hike / Count event; the hike pretty much just ended up a Point Count... 

WE set up on the Upper "Raptor Ridge" trail, below the upper trees to the north east, on that bluff over looking the "football field" as it was windy down along the coastal prairie and overlook... We sat / stood in awe and watched the parade of Accipiter's and Broad-winged Hawks..

The shear fact we had both Dark and Light Morph Adults accentuated the experience, and add in the Juvenile birds and the BWHA workshop was complete.... 

Fantastic experience for the group and great memories for many who got a life bird on this special day.

(photos below of the Broad-winged's are from professional photographers, these photos are indicative of what we saw, but not the actual birds we saw, using them as reference and educational use only)

Luckily the whole group was able to get onto {thanks TWC and WCHW} for suppling some extra binocs so everyone could enjoy these highly migratory, small, compact Buteo's. 

This day ties, and possibly breaks the earlier record up at Jenner for BWHA's.

A lot of the plans for Jenner Hawk Migration monitoring were conceived by Dan Nelson's records of Hawk Migrations on of Bay Hill road in the 1990s and early 2000s and documented in his Madrone Audubon sightings as well as Jesse House who also was instrumental in some of those early west counties surveys....

Lucky to be able to get up there and count these hawks, thankful for all the volunteers, counters, spotters and ultimately the day leaders.

Keep up the great work .. 

Also on this day of 9.26.2021: 
19 Coopers Hawks 
8 Sharp-shinned Hawks 
36 Red-tailed Hawks [3 were juv]
23 American Kestrels 
4 Northern Harriers 
21 Turkey Vultures

great information on Accipiter's. (tools for your tool kit) Wing Tips: Sharp-shinned and Cooper's Hawks

Wing Tips: Sharp-shinned and Cooper's Hawks
click link above for more helpful information 

The Sharp-shinned Hawk (Accipiter striatus) and Cooper's Hawk (Accipiter cooperii) are two closely related birds of prey, and pose an identification challenge that some ornithologists used to consider unsolvable.

These two species belong to the genus Accipiter, which contains about 50 other species worldwide. Only one other accipiter, the Northern Goshawk, is found in the USA and Canada. Accipiters' short, rounded wings and long tails are well-adapted for maneuvers in forested habitats.

In today's post we'll discuss how to differentiate this duo while perched; many of these traits can be used for in-flight ID as well. One of the most important themes in this post is that no field mark is reliable on its own. Thus, let a majority of traits lead you to an identification. If there's no majority, it's better to be uncertain than inaccurate!

Diopter locking mechanisms


Diopter locking mechanisms

by Diane and Michael Porter

Some binoculars (especially high quality, expensive ones) have locking mechanisms to prevent the diopter setting from getting turned accidentally. The locking mechanisms are varied and often ingenious.

On the Minox HG binocular, you unlock the diopter adjustment mechanism by lifting the silver ring on the right eyepiece (revealing the scale) and turning the ring. When you have it right, you push the ring down again, and the diopter setting is locked until such time as you need it again.


The Leica Ultravid roof prism binocular has an especially elegant diopter solution. There are two knobs on the central column.

Normally, when you are using the binocular, both knobs turn as one, so it's like one big, easy-to-find knob. It looks like the picture above left.

To change the diopter adjustment, you lift the upper knob. The right-hand picture above shows the knob in the up position, revealing a stripe of red. In this position, the upper knob turns independently of the lower focusing knob, fine-tuning the focus of the right eye only. As the knob turns, you can see the adjustment on the face of the scale.


If you are not clear about where the diopter setting is on your binocular, consult the manual that came with it.

Armed with this understanding of the diopter adjustment, you can allow your binocular to do its best for you.
