Common Merganser Looking for Fish

I've learned so much this winter while leading bird walks at Cattail Cove State Park, some things just from daily observations, some things from research, and some things from participants on the bird walk.  This piece of new knowledge came from a participant a few weeks ago.  We were watching a couple of Common Merganser females swimming along the surface of the water with their head partially under water like this photo I took today.  I hadn't given it much thought, but the participant asked if the duck was possibly looking for fish.  The light went on, of course!  As you may notice her head is just under the surface to the point of allowing the eye to see under water.

This photo is taken of the same bird, a mere 10 seconds later after an unsuccessful dive.  I now have a new understanding and appreciation for the times I see this behavior.

Great Basin Whiptail Lizard

This Great Basin Whiptail is the latest addition to the Cascade Ramblings Critters section, a proof positive that I look at other things than just birds all the time.  Buster has taken a shine to lizards, after all there are not that many squirrels here in the desert where we are for him to chase, but he has picked-up on the idea that lizards hang around the creosote bushes, so our walks mean he checks out each creosote bush for lizards. Today he found two of these medium sized lizards out enjoying the sun.  Larger than the Side-blotched Lizards he has found out on the trail, these were along the sidewalk, and lucky for the lizards, or most probably Buster, they were on the other side of a chain link fence.

New Nest Construction

A participant in yesterday's Bird Walk at Cattail Cove State Park showed me an strange nest she had noticed in the north end of the Cactus Garden.  I wasn't sure but thought it was possibly a Verdin nest.  I returned for a second look in the afternoon and discovered a pair of Verdin busy with nest construction.  Taking into account  that they have no hands, only their bill to weave an estimated 2,000 twigs into place, it's a remarkable feat of workmanship.  They build a sphere shaped structure, hollow in the inside, with an entrance on a low corner.  We watched them zoom in and out of this entrance hole as they worked inside and out bringing twigs to strategically put in place to make a strong nest. They will finish by lining the inside with feathers for a soft surface to lay her eggs.  I have been hoping to find an active nest for the past month, but had only been able to find four older sites, so this was a pretty exciting find.  We will be visiting this new nest site with my Bird Walk group daily to monitor the busy activity.

Sneaking Up Behind Us

I am frequently asked if we see any Roadrunners here at Cattail Cove State Park, today we did.  This afternoon while I was in the motor home working on my observation bird list for eBird, Jeanette called to me from outside, "Jim, a Roadrunner!"  I grabbed my camera, slipped into my crocks, and stumbled out the door.  Lucky for me my camera was able to find this Greater Roadrunner climbing up the rocky slope behind the motor home, presumably looking for lizards.  Jeanette and I were both surprised at how quickly he was able to climb up such a steep slope.  Everyday we are amazed here at Cattail Cove at the abundance of wildlife, particular birds, on the water, in the campground, and right here behind our motor home.

Progress in the Digital Age

Common Goldeneye (immature male)

The digital age is such a exciting and rewarding time to be involved in birding. Great strides have been made in cameras, enabling even a beginner to take good close-up photos of birds.  The Internet now provides amazing tools to accumulate huge masses of  information on bird populations and migration. A world wide data base called eBird is probably the best example of the use of the Internet to collect and share information.  In the past year they have made it extremely easy to post and share photographs.  My volunteer time here at Cattail Cove State Park has piqued my awareness of the gigantic progress that has been made to birding.  Today, Arizona State Parks installed a link for eBird's Illustrated Checklist at Cattail Cove State Park on the park's web page. You can now look at all the species that have been reported,  bar graphs of the observations, and most importantly photos.  For example by looking at this Illustrated Checklist, and checking on Common Goldeneyes, you can note the latest observation, the bar graph for the times it has been seen, and in this case, photos of adult males, females, and immature males, in order to learn the differences.

Update on the Great Horned Owl

On Monday Feb 5th, I decided to take the people on my Bird Walk up to see the owl.  I had people from California, Washington, Oregon, and Colorado.  The California people were Mike and Jan Wacker from Chico who had attended my bird walks at Buckskin Mountain years ago, and have continued to stay in contact with us. I wasn't 100% sure the owl would be there, but it was, and everyone was delighted.  I am now some what certain we have a nesting female.  It even appears she has managed to move a rock to the front of the cave.  You can notice the difference by looking at the former post. Perhaps her lower profile suggests she is sitting on eggs. I will continue to update as soon as we are back at Cattail Cove, right now we are taking couple of days off in Parker to bird with John West at Ahakhav Tribal Preserve, see the bird list here,  and shop for groceries.

The Great Horned Owl Quest

Since arriving at our hosting site in the over-flow lot at Cattail Cove State Park a month ago we have been on a quest to see the Great Horned Owl.  We hear an owl, or owls every night at some time between dusk to dawn.  Their hoot-hoot-hoot echos between the canyon walls surrounding our parking lot.  A few days ago a camper here spotted an owl at dusk and six of us got a fleeting glance of several short flights, and I got a very poor quality photo.  Yesterday morning just after 7:00 a hoot- hoot sent us scrambling out of our RV in the early morning darkness and we spotted a profile on the canyon rim from where it was calling, and I got another poor photo, shown below. Then last evening just after 5:00 a faint call prompted Jeanette to make another determined effort to locate the owl.  This time she hit the jack pot and found the owl in a small cave in the above photo.  We at first jumped to the conclusion that this was the nesting female, but when we returned some twenty minutes later to locate a second calling the cave was empty.  Our conclusion is that this was just a day time resting spot for either a male or female.  There is a known nesting site, used in past years on the north canyon wall, but so far we have not seen any activity there. It's getting late in the season so we're not sure what the nesting situation is.  This photographed sighting is a significant event in our quest, but still leaves our search open as we continue to hope for an active nest. As I am finishing this blog at 6:00am I hear a male calling on the cliff to the north and a female answering to the south.  Our quest continues.

Spring on the Colorado River

This singing Black-tailed Gnatcatcher male says it all, spring has sprung on the lower Colorado River. Bird song fills the campground here at Cattail Cove State Park. Birds of all species are pairing up. Males are busy either proclaiming their territory or attempting to attract a female. Today I saw a pair of House Finches inspecting a bird house. Trees and shrubs are greening up. Fremont Cottonwood trees seem to have leafed out over night.  Day time temps are consistently in the low eighties. The daylight is starting to last a little longer in the evening. Spring starts earlier in the South-West, and birds need to get serious about nesting to get it done before the oppressive heat of summer. Migrating birds have a different strategy, they head north to cooler climates to breed and raise their young. I was reminded of that this morning when a huge flock of Canada Geese flew over, headed north.  We are starting our last month of volunteering at Cattail Cove for this season, the time seems to be speeding by, and we too will soon be heading north to enjoy a spring in Oregon.
