  1. Let me ask you this.  There was a large flock of gulls out in the middle of the lake.  From the photos I shot panning from one end to the other, I counted over 600 birds.  As I was counting them I didn't notice anything that looked like something other than a gull -- except for one cormorant.  About 10 minutes later a big portion of the flock started flying, and the 3 photos I posted are a few of the shots that I took.

    I don't know how to report a large flock of gulls.  I've avoiding posting some of my checklists because I don't want to leave out gulls, but I don't want to mis-report them.  Everyone that has been reporting this flock at this location to eBird has been reporting them as one of these two:

    gull sp., Larinae sp.
    Larus sp., Larus sp.

    Would one of these two be the correct way to report this flock?  Thanks.

  2. Alex, I'm not asking for IDs of individual birds in the flock.  I'm just asking if you see any species other than California Gulls or Ring-billed Gulls.   You can say, "No", or "a few Westerns" or "at least one Glaucous-winged" -- something like that.  I'm just wondering if all that can be seen and identified are California and Ring-billed.  Thanks.

    Just curious, are there any other identifiable gull species in these shots besides California or Ring-Billed?

    The eBird reports for this location over the past 2 weeks have reported many individuals specifically as California Gulls and many as Ring-Billed Gulls.  Then the large flocks of 100 to 200 have been reported either as "gull sp., Larinae sp." or as "Larus sp., Larus sp."  There was only one Western Gull reported during that period, and 2 (possibly 3) Herring Gulls -- with photos.

    Thanks.

    Are you sure they are the same? Those look like they could be an immature. https://macaulaylibrary.org/asset/20917171

    Jefferson, I think they are the same bird, but possibly not.  The 5 shots I have before the original photo I posted were over water.  Then the 3 shots in sequence.  It would be odd that I would have just a single shot of a swallow in flight.  Unfortunately my camera only records the time to the minute, not the second.

    Here are a couple shots taken in the following minute:

  5. Taken 3-2-2021 above the Los Angeles River at Newell Street in Elysian Valley.

    I'm thinking this is an Orange-crowned Warbler, but not confident.

    I think all four photos are the same bird, but could possibly be two birds.  It was moving around quite a bit and hard to get a shot before it moved again.  I lost sight of it a couple times.  There was at least one other bird in the tree, which was a YRWA, so I was seeing movement from more than one place.

    I’m not sure how serious you are being here or not, but NSHO x COME has never been recorded. It’s not a known hybrid combo, FWIW.

    Hybrid should never really be the default thought process. There is lots of variation within species when observing birds. Although ducks are known to hybridize somewhat regularly, it pays to understand variation within a species first and foremost.

    Not being serious, but thanks for the advice DLecy.
