CORCORAN LAGOON BEACH 
HABITAT

"Examine each question in terms of what is ethically and esthetically right, as well as what is economically expedient. 
A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community.

It is wrong when it tends otherwise."  Aldo Leopold


    Pictures of shorebirds were taken when there were no dogs off-leash present. In some cases, off-leash dogs chased the birds away after the pictures were taken. While humans are rarely seen as a threat by shorebirds, canines, especially off-leash and running around, are always perceived as predators by avian species.

eBird - Global tools for birders, critical data for science

A real-time, online checklist program, eBird provides rich data sources for basic information on bird abundance and distribution at a variety of spatial and temporal scales. eBird is organized in "Hot Spots," locations where birders report significant birds sightings. Among the many Hot Spots in Santa Cruz County is Corcoran Lagoon Beach.

    For the past month, egrets have been feeding at the lagoon outflow on Corcoran Lagoon Beach (see pictures HERE).  They do okay until the unleashed dogs show up, as more than four did this morning.  I saw one unleashed dog chase some of the egrets that were feeding in the outflow of the beach.  Dog owners apparently think it is not only to violate the leash law but also okay for their dogs to harass wildlife.  whatever they think (or don't think), their irresponsible behavior ruining it for those who cherish the Monterey Bay National Marine Sanctuary and its wildlife.

    Early afternoon on Corcoran Lagoon Beach and it's a birdy world at the end of the lagoon outflow...that is until these birds were approached by an unleashed dog.  It happened too fast to get a picture of the disturbance.

    This leashed dog, a frequent visitor to Corcoran Lagoon Beach, is fascinated by a gopher at the beach entrance.  This shows how dogs and wildlife can co-exist if dog owners will respect the leash law while at the beach.

    These birds were very sensitive to dogs.  There was a woman out on the beach throwing a ball for a dog.  If she threw the ball in the birds' direction they flew, despite the fact that the dog never came closer than 200 feet.  That happened three times, until the woman noticed me, then she leashed up and left.

    Four Killdeer chicks have fledged from the first nest of the 2015 season.  Since the inner lagoon is full and offers no exposed edge feeding habitat for the chicks, the Killdeer family has stayed on the beach this year, feeding and resting along the lagoon outflow habitat instead.  The birds return to the protection of the cordoned area at day's end.

    There have been more breaches of the Nesting Protection Area by humans and dogs this year than last year.  To date, however, predators (e.g., crows, raptors, raccoons, etc.) have not been successful within the protected area.

    Merganser  (Mergus serrator) seen in lagoon outflow on Corcoran Lagoon Beach.  These birds will usually be seen in the inner lagoon, where they are generally safe from being chased by unleashed dogs.  Conditions this year have created a fuller and deeper lagoon on the beach, showing that nature doesn't do political boundaries.  Many bird species, like this Merganser, are in their watery habitat, wherever it is.

Snowy Plover at Corcoran Lagoon Beach nesting area!!!

    Snowy plovers (Charadrius nivosus) have not nested at Corcoran Lagoon Beach since their last nest in 2000, due mostly to lack of shorebird nesting protection management.  This changed in 2013 when Friends of Corcoran Lagoon Beach (FoCLB) formed specifically to assist the County in implementing its Local Coastal Program (LCP) policy to protect shorebird nesting areas on County Beaches.  

    With protection of a small area of the beach located close to E.Cliff Drive, the bird nesting seasons  of 2013 and 2014 produced a total of four nests, 16 eggs and 15 successfully fledged Killdeer (Charadrius vociferus) chicks.  The work by FoCLB included installation of signs (bilingual), a simple cordon to delineate the area, exclosures of nests when necessary, daily monitoring and photo-documentation of the results.  

    The area is small and beach visitors are able to continue to access the beach from four different directions without disturbing the birds.  The educational value for beach visitors has been an added benefit.

    Although all bird species, whether endangered or not, are covered by the County General Plan LCP, when we started our work we did not know if Snowies would ever nest again at CLB.  The area is not designated "critical habitat" for this endangered bird and most avian ecologists think that CLB is not really very suitable habitat for successful nesting by Snowies, given the amount of use of the beach.

    Snowy plovers may have a different thought.  This year, the third season of nesting area protection, a Snowy plover finally visited Corcoran Lagoon Beach!  A known female (leg bands identify her), who has nested three or four times at the Pajaro River mouth, stopped by and settled in for most of a day on April 6th.  She has not been seen since and probably continued to her normal nesting area.  Still, it was remarkable that she appeared at CLB.  We welcomed her like a long lost family member!

1:30 pm      These Snowy egrets were at the shoreline of 26th Avenue beach area, east of Corcoran Lagoon Beach.  It is unusual to see them there.  We think that stepped up enforcement of off-leash dogs may be part of the reason.  LLASCC and the birds thank County Animal Services.

10:30 am     This mother duck and her babies travelled from Corcoran Lagoon Beach to the inner lagoon.  When they it made over to the sand spit shown in this picture, a Killdeer chick came out from hiding and stared at them. These ducklings are almost three times the size of the killdeer chicks.

6:50 pm     With no dogs near the rocks of the eastern edge of Corcoran Lagoon Beach, these Whimbrels safely fed at the shoreline.  At the western edge of the beach, where two off-leash dogs were in and out of the water, chasing balls tossed for them, no birds fed at the shoreline.  The number of birds on the beach are increasing as the number of off-leash dogs decrease.

It has been a tough season so far for nesting birds at Corcoran Lagoon Beach.  The original Killdeer nest in the ice plant area was abandoned, leaving three eggs in place. That nest was occupied on March 18th.  During the night of March 18th someone was setting off M1's on that beach.  The nest was found abandoned the following day.  Since the 19th the eggs have disappeared.  The two mallards, who had begun to build a nest, are dead on the side of the road.

After fits and starts and a lot of stormy weather that saw the sky open and dump a lot of rain and blow things around, the resilient Killdeer have come back to celebrate spring with another nest.  Here one of a pair sits on the nest, while the other is feeding down by the lagoon outflow.

These birds are the least tolerant of humans and dogs that I have witnessed at the lagoon. They both took off when a woman and her dog walked over the bridge. The other birds take no notice of what is up on the bridge. I've seen these birds before, but they are so skittish that they are hard to photograph. They are usually trying to look invisible.

    Semipalmated Plovers (Charadrius semipalmatus) are migratory through Santa Cruz.  They forage for food on beaches, tidal flats and fields.  They nest in Canada and Alaska and winter in coastal areas of the southern United States, the Caribbean and much of South America.

    Theses plovers were doing fine until a guy with a cell phone stuck in his ear allowed his three small dogs to enter the lagoon near the birds. The birds took off and landed again near the bridge.  When I was photographing them, they came within 15 feet of me; seemed to have no fear of me.

California Pelican
    California Pelican, injured with a lure stuck into its back, trailing five feet of fishing line, was using the Corcoran Lagoon outflow and its beach area for rest from difficult flight. As can be seen from the first picture, the pelican was adjacent to this season's Killdeer nesting area. This is an area proposed for off leash dog hours and there were seven dogs that came to the area off leash. Owners were warned to leash their dogs. Most did but some owners had no leashes with them.

Native Animal Rescue was called and came to collect the bird, although it took a couple of hours of constant diligence to protect the bird prior to their arrival. Our sincere thanks to Native Animal Rescue (http://www.nativeanimalrescue.org/). They accept donations to help in their work to rehabilitate injured wildlife.

Killdeer and fledglings.
    I had to chase the crows off three times tonight. The final time, one got behind me and attacked a parent killdeer who was doing the diverting behavior. The killdeer took off and led the crow on a wild chase out towards the radio towers. The crow never had a chance. One of the adults gathered a chick in under it's body and protected it.

    I was thinking that the crows hadn't caught on to the babies, but I was wrong.  Just before I left, a baby was on the high ground and a single crow returned and swooped in on the baby.  It zoomed over the top of the baby, missing it by a foot, with a killdeer right on it's tail. The crow got chased out of the area.

    At one time, someone let a firework off.  Scared the crows, but didn't bother the killdeer.

Update on Killdeers and Crows

Picture
    I've been fighting crows. Sunday night two crows were after one adult killdeer and had it cornered in some vegetation, so I went up onto the sand and chased off all the crows.  It's easy; chase one and they all fly away.

    Tonight, both adults diverted most of the crows off across the beach.  One of the babies, who seems to have no fear of crows, or perhaps it froze within plain sight, was being approached by a crow, which got within three feet of the baby, so I went over the wall and chased that crow and all the others off.

New Killdeer Nest at Corcoran Lagoon Outflow

On Sunday, a second Killdeer nest was discovered on the open sand east of the Corcoran Lagoon outflow. Neighborhood volunteers put protective fencing around the nest. The birds moved back to the nest immediately after they were done.

Killdeer Hatched!

    We have four baby killdeers.

    They don't know how to "freeze" yet and when someone approaches they run back into the exclosure.


    The second time I visited them today the parents were showing them how to freeze. Instead of doing the broken wing thing, the parents were freezing low and looking like driftwood.

   This long-billed bird is probably a whimbrel (Numenius phaeopus), seen here with the killdeer, at 11:15 am, in front of the apartments where the outflow is blocked off from the ocean. The whimbrel is one of the most widespread of the curlews, breeding across much of subarctic North America, Europe and Asia as far south as Scotland.
