Info about Cormorants in Monterey Bay

This is a response about the dead birds being found in Elkhorn Slough from Kerstin Wasson, Research Coordinator at the Elkhorn Slough National Estuarine Research Reserve:

It appears that these dead birds are part of a larger event — a lot of cormorants and grebes have been dying of starvation due to lack of anchovy food resources this spring.  Vets have conducted fairly extensive tests and have thus ruled out all diseases that might be expected.  So while sad, this appears to be part of natural cycles of richness and scarcity in the ocean.

Below are links from two recent articles on the subject.

Dead Cormorants

Posted by  Kenneth Weidner.  (we are looking in to this and will post what we know)

Yesterday, (April 30th, 2009) my wife and I visited Elkhorn Slough for the first time. We were both amazed by beauty of the slough and the abundance of wildlife. However, we came upon what appeared to be a mini-holocaust for cormorants. We tried to count the number of corpses but because they were slightly above us while kayaking; and they were so close together it was difficult. My best guess was at least 10 and possibly as many as 20 dead cormorants in a 6 ft. by 4 ft area. I reported it to the monterey kayaking people but they seemed to think it was a natural occurance. It didn’t appear nautral to me but I’m no expert. I would appreciate comments from someone with expertise. I’ve several photos if you would like to see please send me a request at the email above.

Birders Needed at Elkhorn Slough

SPRING MIGRATORY SHOREBIRD MONITORING
Please join us for the second spring shorebird survey to catch the migrants as they move through the area as well as census the resident shorebirds.

Tuesday, April 14, 2009

Teams of volunteer birders will be counting birds within defined areas along the main channel (by boat), and at four walk-in estuarine sites. We particularly need help from expert birders (i.e. those that can readily identify the various species of waterbirds and shorebirds), but also welcome novices to count easily identified species. Please RSVP if you can join us, and list your first and second choice locations:

Main Channel boat survey 7:00am-11:00am
North Harbor (Jetty Road), 8:00-10:00am
Parson’s Overlook, 8:00-10:00am
South Marsh, 8:00-10:00am
North Marsh 4:00-6:00pm

Nest boxes at Elkhorn Slough Reserve

The Elkhorn Slough National Estuarine Research Reserve just posted an update of their research monitoring bird nest boxes at the Reserve.

http://www.elkhornslough.org/research/PDF/2008_nestbox_report.pdf

Volunteer Shirley Murphy is checking a nest box with a flashlight and small dental mirror so as not to disturb chicks

This program monitoring about 150 nest boxes in the oak woodlands of ESNERR began in 1998. Each spring and summer the nestboxes are monitored weekly by a team of volunteers. By carefully checking the boxes and consistently recording what they see, the volunteers are able to obtain data on:
- nest box occupancy (which boxes are occupied and by which species)
- phenology (timing of reproductive events)
- indicators of reproductive success (clutch size, hatching rate, fledging rate)
- parasitism (blowflies in nesting material)

Monitoring these parameters serves as one way of keeping track of the health of oak woodland communities around the ESNERR over time. For instance, dramatic declines in nest box use or fledging rate would serve as a warning signal alerting managers to potential problems in these habitats. These data also would motivate a search by researchers for new negative environmental influences in the area.
