Hi Everyone!
Greg Clark, Burrowing Owl Project Coordinator for Wild at Heart, introduces the ten burrowing owls to be released into Zanjero Park, Gilbert.

Greg Clark, Burrowing Owl Project Coordinator for Wild at Heart, introduces the ten burrowing owls to be released into Zanjero Park, Gilbert, Fall 2011.

I apologize for being way overdue in giving you an update on the owls at Zanjero. With that said,  I can’t go into too much detail right now but in short we have two pairs in full courtship mode, each madly prepping one or more burrows as a nest burrow. The males are also getting very protective starting to dive bomb dogs being walked along the sidewalk.

The pairs are 90X,  banded as female but actually a male, and a local female – their territory encompassing the whole east-side burrows. The other pair is the local pair that came in together back in October at 15/16. This female was not seen for 2 months-don’t know if she left or just stayed unseen in the burrow for all that time.
Three weeks ago I finished up supplemental feeding the owls with frozen mice. 90X is still looking for them when I am doing the pellet counts. Lots of insects out there, though, and an occasionally rodent.
Speaking of the pellet counts I am looking for someone to take on that project for me. It would require a once a week commitment, a day of your choice other than Wednesday when we do the monitoring. It takes me a good 2 to 2-1/2 hours to complete. Dissecting the pellets on the spot as you see and record them.  Plus some minor computer data entry. It could be done any time of the day allowing for good light. It could also be divided up between two people but you both would have to be out there at the same time. I would train you and do it with you until you are feeling confident about it. If you have any other questions, let me know.
Happy Owling!

Audubon launches multistate Rivers Advocacy Network

Black-crowned Night Heron

Black-crowned Night Heron

In the arid West we are all connected by rivers; they are the lifeblood of our land, our economy, our way of life. Western rivers—including the Colorado, the Verde, the Gila and the San Pedro, provide water for tens of millions of people, including twenty-two Native American tribes and the cities of Denver, Phoenix, Albuquerque and Tucson.

We aren’t alone in our reliance on western rivers. Ninety percent of Central Flyway birds depend on these waterways for their survival.

Unfortunately our rivers are in jeopardy. Drought, invasive species, over-allocation and unsustainable management are running our rivers dry. Many of the birds that depend on them, like the Western Yellow-billed Cuckoo and Bell’s Vireo, are in decline, and the future of the communities and economies surrounding our rivers is uncertain.

Audubon is taking a major step to address the threats to our western rivers. This spring we’re launching the Western Rivers Action Network, a multistate grassroots coalition to advocate for our rivers and the bird species that depend on them.

To lead the development of the Arizona network, we’ve engaged Sarah Luna, a seasoned conservation professional who brings a MGatRioSalado7wealth of skills to Audubon. Sarah will be reaching out to Audubon members across the state to get your input on how to make the Western Rivers Action Network a success and to find out how the network can support your chapter’s riparian conservation work.

Interested in being a part of the Western Rivers Action Network? There are many opportunities for volunteer advocates! Contact us to find out more. Email riosalado@audubon.org or Sarah Porter at sporter@audubon.org.

Zanjero Park Burrowing Owl project update

Desert Rivers Audubon, in partnership with the Town of Gilbert and Wild at Heart raptor rescue, installed a burrowing owl habitat at Zanjero Park, Gilbert, AZ (Lindsay Rd. & 202 Fwy.), Fall 2011. Project made possible by a grant from TogetherGreen.

At the end of October the morning monitoring group began picking up and examining pellets at the burrows to confirm what the owls are eating. A trend of insects and not rodents has been established. Being next to agricultural fields,  it was expected for rodents to dominate their diet. At first we wondered if the farmer was putting down a rodentcide. Greg Clark recently discovered a researcher, in the Imperial Valley where 70% of California’s burrowing owls reside, who found only .2 % of pellets contain rodents. His explanation is that the flood irrigation eliminates rodents. Maybe this is what is happening here as well.

Not knowing if insects could sustain our remaining 5 owls through the winter, I was convinced to do a short-term supplementary feeding of frozen white mice. I began this on January 16th. Greg and I decided we should learn something from doing this as well.  I first wanted a basic question answered – how long will it take a mouse to be regurgitated? Answer: 2 to 3 days. Greg suspected that the owls were not regurgitating all of their pellets at the burrows and if so, we thus were not seeing all that they eat. This has turned out to indeed be the case. Only a small percentage of the white mice pellets are showing up. Some weeks more than others. And those that we do find are a combination of mouse and insects, sometimes very packed with insect parts. I am feeling better that they are finding insects in the winter.
Please join us  Saturday, February 23rd from 8 to 11 am at Zanjero Park for a Volunteer Clean Up Day.

Now onto the owls themselves. 90X is her usual, confident self residing at #50, although of late she can be seen all the way down to #37 in the afternoon. This is due to the fact, I surmise, that 88X has not been on site since 1/9 and #37-46 was her “territory”.  No signs of predation in the park this time as was the case with the last two owls. The female of the local pair at #15-16 has not been seen since 1/9 either but because she is so secretive and because it has been so cold I’m not completely convinced she still is not there. The really AWESOME news is the release site local owl who I had started to suspect was male has joined 90X at #49-50.  Last week a regular park walker and the evening monitoring group saw them together at #50. Courting behavior was going on and the male has been named Whitebeard. (He really extends his white chin feathers very long when doing a courting display). This morning we watched Whitebeard come out of #49 and 90X out of #50. If you go out to see them Whitebeard flies easily if approached too close.

A decision on whether more owls will be relocated to Zanjero this Spring is still being reflected upon. Greg Clark is waiting to hear the information the farmer has, how stable the food supply is, and how many migrants will arrive on site in February into early March.

Join Desert Rivers Audubon for the Great Backyard Bird Count February 15-18, 2013

Kick-off Saturday, February 16th @ Gilbert Riparian Preserve

Join Desert Rivers Audubon at the Gilbert Riparian Preserve at Water Ranch, 2757 E. Guadalupe Road Gilbert, to kick-off the Great Backyard Bird Count, Saturday, February 16, 2013, 8am-12 noon.

The goal of The Great Backyard Bird Count is to watch birds for at least 15 minutes on one or more days of the count then enter tallies at the Count’s website. Watch live data coming in and look up your area by zip code to see the Count progress in your city. Anyone can participate; it’s free. Participants can count anywhere they wish, not just in backyards, but in neighborhoods, parks, nature centers, or anywhere they see birds.

The Great Backyard Bird Count is a joint project of the Cornell Lab of Ornithology, National Audubon Society, Bird Studies Canada and sponsored by Wild Birds Unlimited.

“This year’s count will give us a whole new perspective as sightings pour in from around the globe in real time,” said Marshall Iliff at the Cornell Lab of Ornithology. “Millions of people encounter birds every day all over the world. Imagine what scientists will learn if each one of us shares observations from our own area!

“Once again, we’ll be able to coach East Valley residents in their bird identification skills Saturday during our free Family Birdwalk at Gilbert Riparian Preserve, Saturday, February 16, 2013, 8am-noon,” added Eileen Kane, Communications Director, Desert Rivers Audubon Society. “We hope to see those citizen scientists who helped us last year as well as new folks interested in knowing more about their neighborhood wildlife. Kids can count, too!”

During the 2012 count, participants reported 17.4 million bird observations on 104,000 checklists.

Keep watch for American Goldfinch.

“The GBBC is an ideal opportunity for young and old to connect with nature by discovering birds and to participate in a huge science project,” said Gary Langham, Audubon’s Chief Scientist. “This year, we hope people on all seven continents, oceans, and islands, will head out into their neighborhoods, rural areas, parks, and wilderness to further our understanding of birds across the hemispheres.”
