Banded Snowy Plover - May 5, 2007

I think this banded Snowy Plover (BOAO) has been showing up at Coal Oil Point Reserve since 2004. A younger version of BOAO can be seen on the 2003 and 2004 Banded Snowy Plover page.

Coal Oil Point Reserve 04/30/06 - Banded Snowy Plover during nesting season - This banded bird was also here in 2004 and 2005

  
BlueSilver:Yellow(Aqua?) was here photographed here on January 24, 2004 and March 30, 2005
(? about coloration differance at shoulders and crown of head - seasonal differences or color reassignment?)

 

P:GOG was banded at VAFB as a chick in '03 and has been seen at COPR Dec. of that year. � GB:OW was banded last year as a chick at Pajaro Spit, was at COPR in Nov.�

(note this is an older letter from Cris regarding Plover banding)

I hope you had a good holiday break. My family was here and I had a great time. Thank you all who were able to come to the Reserve during the holidays. I know this time is specially difficult for most of you.


I am sending you a word table with information about the plovers that are banded and observed at Coal Oil Point Reserve. I update this table once a week, so I will send you the latest table once in a while.


Melissa Kelly, who is a docent on Sundays at day break, is the official volunteer for Point Reyes Bird Observatory (PRBO). She is doing an amazing job recording plover bands and counting them about once a week. I then send this information to PRBO and they send me back the information about the origin of the banded plovers. PRBO has a huge database to track the movement of various bird species. With this information they can watch for declines, trends, etc.


The movement of plovers between inland and coast was an essential information to determine that inland and coastal birds were separate populations that did not mix during the time of breeding. It is because of this information that the coastal population of snowy plovers were listed as threatened. When last year a group of people petitioned the US Fish and Wildlife Service (US FWS) for the plovers to be de-listed, I was able to use the banding information to show that they are indeed separate populations (see attached letter to FWS).


How can you use this information for the Reserve? The number of plovers from different locations observed at COPR may only represent the banding effort at different locations. With the information on the table attached all we know are possible locations where our plovers come from. Few plovers from the south may only mean that plovers are not being banded in the south. We can say that our plovers are coming from various locations. This year we even have a plover from Oregon.
Are we going to band plovers at COPR? Probably not. COPR has problems with predation from visually oriented predators such as crows. The bands are brightly colored and may increase predation risk to young chicks.


Where do the plovers that breed at the Reserve come from? Nobody knows because the plovers that have bred here were not banded. We know from other well studied areas that 60 % of the plovers come back to the original site where they were born to breed in their first year. Thanks to the 40% that are more adventurous we had plovers breeding here in 2002 after 30 years of no breeding. In 2004, it is likely that most of our breeding pairs will be from chicks born and raised at COPR. I wonder if these pairs will be tame as the chicks were.


Breeding will start at the end of March. We should start a new pool to see who guesses the right number of chicks for 2004.


All the best to all of you.
