Upcoming Events: Public Meetings on Land Trust Conservation Plans

Note: the Land Trust of Santa Cruz County has been developing a "Conservation Blueprint" to guide its land conservation activities.  The preservation of habitats is, of course, a key factor in the conservation of our local birds and other wildlife.  The development of this document thus far has already involved many local people with knowledge or interest in various areas of concern, including quite a few SCBC members.  Now they are seeking further input from the community as a whole, and several public forums for this process are scheduled over the next couple of weeks.  The following is from a press release from the land trust:

Join the conversation to shape a
Conservation Blueprint for Santa Cruz County
Share your ideas about how we can work together to protect our county╩╣s quality of life and maintain our precious land, water and wildlife. The Land Trust of Santa Cruz County is hosting four Community Forums around the County in April and May and wants to hear from you.
Wednesday, April 21st
at Watsonville Community Room in the Civic Plaza from 6pm to 9pm.
Introduction and welcome by Mayor Luis Alejo
Tuesday, April 27th
at the Simpkins Swim Center in Live Oak from 6pm to 9pm.
Introduction and welcome by County Treasurer Fred Keeley
Thursday, April 29th
at the Long Marine Lab Seymour Center in Santa Cruz from 6pm to 9pm.
Introduction and welcome by former Assembly Member John Laird
Tuesday, May 4th
at the Highlands Park Senior Center in the San Lorenzo Valley, 6pm to 9pm.
Introduction and welcome by Supervisor Mark Stone
You can find out more about the Conservation Blueprint at www.conservesantacruz.org
or call the Land Trust at (831) 429‐6116
Forums made possible with support from the Community Foundation of Santa Cruz County
and the Gordon and Betty Moore Foundation

If you cannot attend a forum, please write us and let us know what you think. You can send your answers to us at the address below.
How can land conservation help:
• Sustain the viability of agriculture and the jobs it provides?
• Contribute to healthy forests and a sustainable timber industry?
• Sustain our tourist industry and the jobs it provides?
• Provide clean, safe drinking water?
• Protect the waters off our coast and in the Monterey Bay Marine Sanctuary?
• Provide fish habitat?
• Address the underground aquifer overdraft problem?
• Protect habitats critical for biodiversity of plants and animals?
• Provide connections between large‐scale landscapes like the Santa Cruz Mountains, the Mt. Hamilton range, and the Gabilan Mountains?
• Address climate change and its impacts on plants and animals?

Bird List, Photos, and Notes for April 17, 2010- Upper UCSC Campus

This walk explored the forests, chaparral, and coastal prairies of the upper campus natural area at UCSC.  The area was active with birdlife, and there were good opportunities to compare similar song types- Orange-crowned and Wilson's Warblers and Dark-eyed Juncos, or Purple Finch vs. Warbling Vireo, or Brown Creeper vs. Golden-crowned Kinglet.  Some of the local breeding Hermit Thrushes had arrived, replacing the just-departed wintering Hermit Thrushes, and we heard their ethereal songs in several spots.  In addition to birds, the ample rains this year brought a nice variety of native flowers, including some scarce species, plus mushrooms, insects, a few mammals, and of course the occasional Banana Slug.

Photo Quiz #2

photos by Steve Gerow

This hawk was photographed on the west side of Santa Cruz about a week ago.  Can you identify it?

Answer to Photo Quiz # 1

photos by Wendy Naruo
(See March 23, 2010 post for original quiz, with larger-format photos.)

   This is a bird we encountered on an SCBC field trip on August 28, 2009.  A small, brown bird with a thick-based conical bill and a streaked back suggests some sort of sparrow, but it is not really a good match for any of them.  The very short tail, combined with a flat head sloping into the bill, eliminates from consideration most of the plain-breasted American sparrows, as well as a female House Sparrow.  The closest match is probably Grasshopper Sparrow, but even they don't have this short a tail.  Also, the crown on this bird lacks the distinct median stripe of a Grasshopper Sparrow, the face pattern is wrong (the face pattern on this bird actually looked surprisingly like a Warbling Vireo's, in the field at least), the upperparts (not too visible in these photos) have a less complex pattern; really,  there are quite a few differences in details between this bird's plumage and structure,  and that of a Grasshopper Sparrow. 
   There is also a superficial resemblance to a female or basic-plumaged Bobolink.  The crown pattern is wrong, though, lacking the bold striping of a Bobolink, the tail is too short and lacks the spiky tips, and, again, it differes in a lot of details, as well as being much too small.  Even a review of some far flung rarities (among sparrows, buntings, finches, and similar birds) that might have a slight possibility of showing up here, finds nothing that seems a good match. 
   When faced with such a situation, it is worthwhile to consider the various exotic species that are kept as pets, and may escape or be released.  One of these that appears rather frequently in California is Orange Bishop; there are even some reproducing populations in some parts of the state, that may be more or less established in very localized areas.  The male of this species in breeding plumage is pretty much unmistakeable, but females and basic-plumaged males are more confusing- a small, sparrow-like bird with brown, streaked upperparts, unstreaked cream-colored underparts, a flat head, a very short tail, and. . .well they look just like this bird, which is a female Orange Bishop.  This is not an established species in Santa Cruz County, so this bird is likely an escape, but a wanderer from one of the reproducing wild populations in the state probably can't be entirely ruled out.  So while it is not "listable" by the standard rules of such things, it is worthwhile keeping track of observations of these exotic species; one never knows what might happen.

Bird Lists, Notes, and Photos for April 9, 2010, Natural Bridges & Antonelli Pond

Today's Santa Cruz Bird Club field trip visited Natural Bridges State Beach.  It was a colorful morning, with blue skies, and lots of bright warblers singing in the willows and eucalyptus.  A majority were YELLOW-RUMPED (both forms, but more Audubon's), but there were quite a few migrant ORANGE-CROWNED as well, and a number of WILSON'S.  Bob Ramer spotted a BLACK-THROATED GRAY WARBLER a short distance south of trail marker #5 on the east side of the park, for one of the highlights of the morning.  A BULLOCK'S ORIOLE chattered and sang a few times from the eucalyptus in this area, though we couldn't get a look at it.  There were also a couple of LINCOLN'S and one FOX SPARROW on the east side of the park.  Moving down to the beach, a flock of over 30 SURFBIRDS and a couple of BLACK TURNSTONES were working around the base of the Natural Bridge.  Then another flock of 40+ more SURFBIRDS flew in, landing on the rocks on the west side of the beach, for a nice total of about 75.  There were also about 50 SANDERLINGS, 9 WHIMBRELS, 2 BLACK OYSTERCATCHERS, a SPOTTED SANDPIPER, a KILLDEER, and a couple of SNOWY EGRETS that thought they were shorebirds.  A couple of CANADA GEESE flew over, and the ocean had a couple of PIGEON GUILLEMOTS, migrating PACIFIC LOONS, and other things.  A highlight at the Butterfly Boardwalk was a great study of a very cooperative singing PACIFIC-SLOPE FLYCATCHER.  Among the additions on the west side of the park was a good look at an adult female SHARP-SHINNED HAWK. 
   At the end of the morning part of the group continued on to Antonelli Pond, where we found five species of swallows (including one locally-scarce TREE), and a lone VAUX'S SWIFT sped through the swallow flock.  A calling SEMIPALMATED PLOVER flew over.  Another FOX SPARROW was feeding at the edge of the willows, and a GREEN HERON flew in and landed at the edge of the cat-tails.  One RUDDY DUCK, the last remaining of the small wintering flock,  was also still in the pond.

Bird List, Notes, and Photos for 4/2/10: Moore Creek Preserve


This Santa Cruz Bird Club field trip visited Moore Creek Preserve at the west edge of Santa Cruz. Among the highlights were four WESTERN BLUEBIRDS (apparently two pairs) in the Vernal RIdge area of the preserve, the males looking especially colorful among the large patches of goldfields and other flowers. Two COOPER'S HAWKS in this area were acting like a pair, and one was doing a display flight, though that one was a first spring bird retaining juvenal plumage. Three GRASSHOPPER SPARROWS were singing in the grasslands, though staying well hidden in the grass. There were several SAVANNAH SPARROWS that seemed to be in nesting territories. The wintering WESTERN MEADOWLARK flock was still around, with 50+ birds. A WILD TURKEY was wandering through the grass near Moore Creek Canyon on the upper part of the slope, the first of those I have seen in that preserve. The forest areas had a lot of singing warblers, especially TOWNSEND'S and ORANGE-CROWNED, with some WILSON'S and YELLOW-RUMPED. Deer were numerous, and coyotes were howling and wandering around.
