Terns & Domoic Acid |

Hello
monitors,
As we begin the monitoring, there are a couple of things to
watch for already:
As mentioned at the kick-off, please be on the lookout for
Gull-billed Terns! See the OC Rare Bird Alert below. They
were seen at Bolsa Chica on April 22. Please report any sightings
of them at the tern preserve to either David Pryor or Wally
Ross (phone numbers on the back of your badge). They are a
predator of the Least Tern eggs and their range may be moving
north from San Diego County. (See photo below.) |

Also,
Domoic Acid has just been reported at high levels on April
18 and 22, in the water just south of the LA Harbor breakwater.
This naturally occurring neurotoxin concentrates in fish,
so any marine fish-eating bird could be affected, including
Least Terns. Please take or have the lifeguards take any sick
(usually with seizures or disoriented) birds to the Wetlands
and Wildlife Care Center at PCH and Newland as quickly as
possible. The sooner they are treated, the better their chances
are for survival. I have not heard of any outbreak of sick
birds yet, but just wanted to alert you of the possibility.
If I hear of an outbreak, I will notify you.
Thanks,
Cheryl |
