Observations

  1. Number observed: 1

    Comments: (I saw a lone goose in the lagoon)

  2. Number observed: 22

    Comments: (I counted in the lagoon ten pairs and two additional male Gadwall)

    Age & Sex:
    Juvenile Immature Adult Age Unknown
    Male 12
    Female 10
    Sex Unknown
  3. Number observed: 8

    Comments: (I counted at least five male and three females Mallards in the lagoon, but I could have missed others given that these birds were more widely dispersed than the Gadwall)

    Age & Sex:
    Juvenile Immature Adult Age Unknown
    Male 5
    Female 3
    Sex Unknown
  4. Number observed: 1

    Comments: (a lone bird in female-like plumage was foraging in the surf to the west of the lagoon)

  5. Number observed: 1

    Comments: (a single bird in alternate plumage was just offshore)

  6. Number observed: 1

    Comments: (I saw at least one Western Grebe, but there may have been one or two other, distant Aechmophorus)

  7. Number observed: 2
  8. Number observed: 10

    Comments: (most of the coots were in the river channel just above the bridge)

  9. Number observed: 6

    Comments: (seen on the exposed flats and rocks just off the creek mouth)

  10. Number observed: 1

    Comments: (seen on the flats in the upper part of the lagoon)

  11. Number observed: 30

    Comments: (calling; my best attempt at a count for Whimbrel reached 29 birds, from which I rounded upward; I saw most of these birds well enough to identify as N. p. hudsonicus based on their dark rumps)

  12. Number observed: 35

    Comments: (I counted 37 birds, but given the potential of overcounting, I adjusted the total downward slightly)

  13. Number observed: 27

    Comments: (seen in a single flock along the beach west of the lagoon; some birds were in fine, alternate plumage, but others were still transitioning)

    Media:
  14. Number observed: 75

    Comments: (birds in a single flock along the beach west of the lagoon were still in mostly basic plumage)

  15. Number observed: 1

    Comments: (calling; I heard an unseen bird around the lagoon)

  16. Number observed: 60

    Comments: (my best count of birds in a single flock in the lagoon that appeared to include entirely birds in alternate plumage)

  17. Number observed: 5

    Comments: (calling; none of these birds were in fully alternate plumage, but at least some of them had a few spots)

  18. Number observed: 8

    Comments: (calling)

  19. Number observed: 1

    Comments: I spotted this bird standing alone on the rocks exposed at low tide just west of the lagoon, where it remained until flushed by some dogs just before I was able to get a good photo. Shortly later, I relocated the kittiwake sitting on the rocks with a flock of terns just south of the lagoon, where it remained long enough for me to approach it and get some good photos, yet it had vanished when I looked back at the flock a half-hour later (though I did not expend much effort looking for it at this time). I was therefore able to get good views of the perched bird at close range and I briefly saw it in flight when it flew down the beach.
    This was a small gull that had a medium-length bill, a rounded head, a plump body, relatively long wings, a short tail, legs that seemed short even for a gull, and conspicuously webbed feet. The bill was relatively slim throughout its length and with a culmen that was straight up until the point that it curved smoothly downward maybe two-thirds of the way to the blunt tip. I further the lack of an obvious angle at the gonys and that the bill would have extended backward on the face to a point near the rear edge of the auriculars. The forehead was quite steep, and the crown was strongly yet smoothly rounded on a head that was unremarkable in size. The neck was relatively short and stout, and the body was plump, full-chested, and with a posture that was more upright than horizontal but not quite diagonal. The wings were long, with the tapered wingtips reaching some distance beyond the tip of the tail, and a primary projection that appeared to be comparable to the entire length of the exposed tertials. Although the tail was mostly obscured by the wingtips when the bird was on land, I thought it was short and square-tipped when the bird was in flight. I thought this bird’s legs were conspicuously short even for a gull, and they also seemed to be relatively slim. The feet were fully webbed between the front three toes, but I did not see a hind toe.
    This bird’s plumage patterns were essentially typical of an adult gull apart from a few unique anomalies. The head, neck, and underparts were white and unmarked for the most part; however, I did note a rounded smudge of blackish on the auriculars that was reminiscent of that of a Bonaparte’s Gull but larger and less sharply defined. Further apparent was a diffuse wash of light gray on the back of the neck that was far more subtle than what I would have expected on a young kittiwake. Contrasting with the white of the neck and underparts, the back and wings were light gray and seemingly unmarked apart from a white crescent that separated the tertials from the black wingtips. Beyond this crescent the exposed wingtips appeared to be almost entirely black, but I did think the inner feather or two had a narrow edge of white visible just beyond the “tertial crescent.” I was able to see only a small portion of the tail when the bird was on land, but what I saw appeared to be entirely white. Finally, when I saw this bird in flight I noted that the back and wings were gray, that this bird lacked a dark carpal-bar, that the wingtips were uniformly black and sharply demarcated from the gray that characterized most of the wing, and that the tail was white. I cannot remember noting specifically the lack of tail band, but my impression was that the tail was white to the tip.
    The bill was an odd, yellowish-green in color form the base to the tip, and it clearly lacked red or black markings. I noted that the eyes were dark, but their precise color eluded me. The legs and webbed feet were essentially black, but maybe with a faint purple suffusion in good light.

    Comments: (a bird in the lagoon had a partial hood, but I could not see its wings all that well)

  22. Number observed: 80

    Comments: (my total for Western Gulls represents an estimate)

  23. Number observed: 40

    Comments: (I did my best to count these birds both around the lagoon and as they flew up the beach)

  24. Number observed: 7

    Comments: (I counted seven birds in the lagoon early in my visit, but the total appeared not to vary much)

  25. Number observed: 47

    Comments: (calling; my maximum, single count tallied 47 birds, of which many had full, black caps)

    Media:
  26. Number observed: 300

    Comments: (calling; I repeatedly tried to count the terns, but their movements made reaching a precise count impossible; I would therefor consider this to represent a pretty careful estimate and including mostly birds with fully black caps)

  27. Number observed: 1

    Comments: (a bird in basic-like plumage seen just offshore west of the lagoon)

  28. Number observed: 7

    Comments: (seeing flying west offshore in a single flock that included at least mostly birds in alternate plumage)

  29. Number observed: 1

    Comments: (a bird in alternate plumage on the water west of the lagoon)

  30. Number observed: 15

    Comments: (I counted 12 birds in the lagoon on my arrival and the number appeared to remain relatively stable, but I also saw a few birds flying by offshore)

  31. cormorant sp.

    Number observed: 2

    Comments: (I saw two or three additional cormorants offshore at a distance at which I could not be certain of the species represented)

  32. Number observed: 75

    Comments: (given movements of pelicans up and down the shoreline this is best considered a rough estimate)

  33. Number observed: 1
  34. Number observed: 2
  35. Number observed: 5
  36. Number observed: 2
