Jack Sparrows Spring Birdathon 2008 Trip Report
The Jack Sparrows, Ginger and Barry Langdon-Lassagne, completed our all-day birdathon yesterday. We enjoyed a successful Earth Day birdathon with the weather holding steady despite the forecast of occasional showers. We strove to minimize the environmental impact of our birding by planning a route that minimized our driving. We supplemented our driving by strapping our bikes to the back of our Prius and using the bikes to cover areas that we might otherwise have covered by short-hop driving. Also, we hiked extensively. And we picked up litter in the parks as we birded.

There was no single "bird of the day" for us, no great rarities, but there were many memorable bird encounters. At Picchetti Ranch a family of three HAIRY WOODPECKERs happily fed and called right in front of us. We had gorgeous looks at a WILSON’S WARBLER at the top of Stevens Creek Reservoir. On the reservoir itself a Spotted Sandpiper repeatedly flew across the lake and back, doing its tail-bobbing thing every time it landed. On Salt Pond A1 near Shoreline Lake, at least five BLACK SKIMMERs were snoozing on a small island. We rode bikes from Charleston Slough to Palo Alto Baylands: at the baylands we saw a WHIMBREL and a LONG-BILLED CURLEW near each other - both birds had eluded us last year. BONAPARTE'S GULLs made us happy by flying over at the baylands as well as later at Alviso. As we were biking behind the Sunnyvale Water Pollution Control Plant we got lovely views of two alternate-plumaged EARED GREBEs. After hunting at Shoreline Golf Course, Sunnyvale Baylands, Alviso Environmental Education Center and the fields behind Jubilee we were ready to give up on seeing a BURROWING OWL, but then one helpfully perched on top of a chain link fence as we cruised down Disk Drive! Stopping on the commute up to Ed Levin County Park, we heard and finally found a ROCK WREN and watched several VAUX'S SWIFTs flying among a huge flock of TREE SWALLOWs over Calaveras Road. At Ed Levin park we were pleased to discover the nest of a GREAT HORNED OWL, complete with giant fluffy owl baby, as well as the hoped-for RUFOUS-CROWNED SPARROW (we saw at least five on our hike) and LAWRENCE'S GOLDFINCH. And as night was falling over Alviso, we were delighted to finally hear a WESTERN MEADOWLARK calling; this bird that had vexed us all day by not appearing in its usual locations.
