The Orange County RBA and events summary is produced weekly by Ryan Winkleman and Jeff Bray in collaboration with Doug Willick. Sightings of rare birds can be posted to the OrangeCountyBirding listserv, emailed directly to Jeff Bray ( jbray3928@... ) and/or Ryan Winkleman ( rswinkleman@... ), and/or submitted to eBird ( http://ebird.org/content/ebird ). Any supporting details (descriptions, photos, audio recordings, etc.) of rare sightings that are not already disclosed on the listserv or on eBird should also be emailed to Ryan Winkleman separately for consideration to be mentioned in the current quarterly report for North American Birds.
Those sightings that are included in this summary generally include those that are considered rare (regionally or seasonally) for Orange County based on "The Birds of Orange County: Status and Distribution" (Hamilton and Willick), "Birds of Southern California" (Garrett and Dunn), and/or more contemporary changes in local or regional status and distribution. Rarities that regularly or seasonally occur at a particular location, such as annually wintering rarities on Seal Beach National Wildlife Refuge, may or may not be included in this digest, but reports of these same species occurring at other, atypical locations throughout the county may be included. We don't include hybrids, subspecies, introduced or exotic birds, or in most cases and for no real reason, geese. All bird reports are vetted to the extent possible prior to each publication, but in the interest of sharing information, the accuracy of any given report cannot always be guaranteed, nor can the presence of any given bird for those who choose to chase after them.
Information on upcoming local events is taken largely from the Sea and Sage Audubon website ( http://www.seaandsageaudubon.org/ ). Sea and Sage Audubon is based out of the Audubon House at the San Joaquin Wildlife Sanctuary in Irvine. They sponsor a number of public field trips, special birding events, conservation lectures, and social gatherings throughout the year.

Thanks to all who responded. I saw a bird and I would like to say I saw the eagle. I was walking from Muth Center on top of the cliff along the bike path towards Jamboree. The bird showed up beyond the cliff for two seconds or so, then dipped back under the cliff. From above it was black with a white head. If I had been looking up at it I could have ruled out an Osprey. It was eagle sized, but size impression is unreliable. Should I record a Bald Eagle sighting from this info, or is an Osprey equally/more likely at this location
We did easily find the female Mountain Bird. It was as if it she were waiting for us by the Muth Center parking lot. It was the first bird we saw, so that was good.

I would suggest walking from muth (check the field right by the parking lot for MOBL), along the bike path towards the jamboree bridge. This is where I usually see the Eagle plus both the bridge and muth provide ideal Lookout points. But keep in mind, seeing this bird is mostly a matter if luck.

Good Birding,

Multiple reports of the bird have said that it was at quite a distance, so if you have a scope, Id suggest bringing it. As on where to see it from, I cant comment on that because I havent seen or tried for this individual yet.

Any tips on finding the reported continuing Bald Eagle at Upper Newport Bay I am taking my kid who is on the fence on birding, and I want it to be a productive outing.
The other target will be Mountain Bluebirds reported near Muth Center.
Thanks!

The Orange County RBA and events summary is produced weekly by Ryan Winkleman and Jeff Bray in collaboration with Doug Willick. Sightings of rare birds can be posted to the OrangeCountyBirding listserv, emailed directly to Jeff Bray ( jbray3928@... ) and/or Ryan Winkleman ( rswinkleman@... ), and/or submitted to eBird ( http://ebird.org/content/ebird ). Any supporting details (descriptions, photos, audio recordings, etc.) of rare sightings that are not already disclosed on the listserv or on eBird should also be emailed to Ryan Winkleman separately for consideration to be mentioned in the current quarterly report for North American Birds.
Those sightings that are included in this summary generally include those that are considered rare (regionally or seasonally) for Orange County based on "The Birds of Orange County: Status and Distribution" (Hamilton and Willick), "Birds of Southern California" (Garrett and Dunn), and/or more contemporary changes in local or regional status and distribution. Rarities that regularly or seasonally occur at a particular location, such as annually wintering rarities on Seal Beach National Wildlife Refuge, may or may not be included in this digest, but reports of these same species occurring at other, atypical locations throughout the county may be included. We don't include hybrids, subspecies, introduced or exotic birds, or in most cases and for no real reason, geese. All bird reports are vetted to the extent possible prior to each publication, but in the interest of sharing information, the accuracy of any given report cannot always be guaranteed, nor can the presence of any given bird for those who choose to chase after them.

Spotted Bald Eagle flying over pond 2 at San Joaquin flying NE at 10 am. George Nothhelfer
Mission Viejo, CA

George Nothhelfer - Sent from my IPhone

At 3:15 p.m. today an adult Bald Eagle flew directly over Pond 1 and 2 and was heading west.

Addendum to previous. I am currently (2:46 p.m.) at mile marker 2.25 on Back Bay drive at Upper Newport Bay. The Bald Eagle is flying low over the channel, not much of a channel as it us low tide.
