2nd week of October Fall 2018 survey of this private property. Favorable winds from NW brought tremendous number of South bound migrants. In this CBC style survey Tim and I thoroughly comb through every field. Despite the maximum length survey (dawn to dusk), we had to go though the forest in near near darkness to cover the area. This certainly under-represented the number of most woodland birds, and we missed titmouse for example. However, 20 hermit thrushes, and 2 Swainson's lined up on the path over a 300 yards corridor after sunset. We also heard 6 great horned owls (one seen), and heard a scarlet tanager whistling its flight call for several minutes well after sunset, vocalizing almost into complete darkness. The SW and SE corners of the property were not surveyed, and we did not walk the forested stream. There were simply too many sparrow to count in the fields that are part of a grassland restoration project: the final tally was 868 sparrows from 11 species, including junco and towhee (17 individuals not assigned to the species). An extraordinarily eventful birding day, with non-stop bird action for over 12 hours.

Observations

  1. Number observed: 75

    Details: FLYOVER. Including a flock of 70 loud migrants

  2. Number observed: 1

    Details: Female flushed from stream

  3. Number observed: 7

    Details: FLYOVER

  4. Number observed: 80

    Details: FLYOVER

  5. Number observed: 6

    Details: Few birds observed

  6. Number observed: 1

    Details: Extraordinarily well seen. ID immediately in flight by shape, long tail, and bright rufous primaries. Sat hunched over branch for several minutes, in full sight. Bright yellow bill observed well. May have been flushed from a field.

  7. Number observed: 53

    Details: FLAGGED RARE (late). Surprisingly large flock for the date. Largest flock was 35 at dusk, frantically feeding above field and forest. Other flock 18 about 1/4 mile away (counted), and smaller groups of 1 to 3 individuals during the day (not counted). Impossible to determine if flocks merged given that these birds are such strong flyer, but it seemed unlikely that all birds on the property were all in a small area at dusk. All looked like all black "flying cigars", with very narrow and pointed wings. Obviously swifts, unlikely to be any other species.

  8. Number observed: 3

    Details: FLYOVER. 2 immature all-brown birds.

  9. Number observed: 1

    Details: FLYOVER

  10. Number observed: 2

    Details: FLYOVER high and distant soaring pair. Possible another seen later in same context.

  11. Number observed: 6

    Details: All over the property

  12. Number observed: 1

    Details: FLAGGED RARE. Either flushed from canopy, or was flying flying just above it. Only seen in flight, but great looks by both observers. Looked like Red-tailed hawk to the naked eye (I almost ignored the bird), but diagnostic striped black-and-white tail was observed immediately (adult bird). Rufous underwing coverts, and slightly paler but colorful breast and upper belly. As the birds moved slightly North above the canopy (I don't think it was ready to go anywhere far yet as winds had turned to the South), the white "windows" on the wing were well seen. First record for the property.

  13. Number observed: 9

    Details: Soaring groups of 4 and 3 seen simultaneously and 2 residents in different parts of the property.

  14. Number observed: 6

    Details: FLAGGED AS A HIGH COUNT. All 6 Great Horned heard vocalizing, one seen flying over field into forest. There are at least 3 breeding pairs on this property. Only half the forest surveyed after sunset. 2 duetting, then 1 single hooter, all heard within the woods. At the edge of the fields, where we spotted an owl in flight, we heard 2 birds hooting and another giving a screeching call, all fairly close together. The screech sounded consistent with the calls of younger birds, perhaps this was a hatch-year individual that either hasn't dispersed or has recently dispersed into unfriendly territory.

    Breeding Code: P Pair in Suitable Habitat (Probable)
    Media:
  15. Number observed: 15

    Details: Several seemingly migrating, most foraging around the property. Aggressive interactions observed between 2 individuals.

  16. Number observed: 31

    Details: Despite the high number. Under-represented by lack of woodland surveying. For the first time on property we observed birds that were very likely migrating, 3 birds flying much higher than canopy, heading SSW.

  17. Number observed: 5
  18. Number observed: 4

    Details: Possibly under-represented by lack of woodland surveying.

  19. Number observed: 75

    Details: Estimate. 40 were recorded on the ground, and in trees on the property. Tim estimated at least another another 35 the were flying overhead at canopy high height or just above.

  20. Number observed: 4

    Details: 3 males and a female. All actively feeding. 2 males seen chasing each other. Conservative count.

  21. Number observed: 2
  22. Number observed: 1

    Details: FLAGGED RARE (late). This may be a summer resident. Wood peewee heard from the area all summer and seen in the fall. From Eastern phoebe by strong wing bars, paler head, paler overall, foraging pattern. Seen by both observers, although the bird feeding high in canopy by field edge.

  23. Number observed: 64

    Details: Detailed count of this ubiquitous species on the property. Less numerous than on September 30 (85), but still a spectacular showing.

  24. Number observed: 9

    Details: All in forest edges, certainly under-represented by lack of forest surveying.

  25. Number observed: 75

    Details: ESTIMATE. This is the most problematic species to count on this property. Conservative estimate provided courtesy of Tim.

  26. Number observed: 5

    Details: FLYOVER flock - North bound.

  27. Number observed: 2

    Details: Under-represented by lack of woodland surveying.

  28. Number observed: 0

    Details: Under-represented by lack of woodland surveying.

  29. Number observed: 55
  30. Number observed: 53
  31. Number observed: 14

    Details: Amazing number for the site (mostly hardwood forest). Birds found in forested hedgerows and manicures grounds area, often associated with ornamental conifers.

  32. Number observed: 6

    Details: Under-represented by lack of woodland surveying.

  33. Number observed: 13

    Details: FLAGGED for HIGH COUNT. A detailed count, all seen as singles. All in fields - it did indeed seemed late for this many (13) house wren.

  34. Number observed: 8

    Details: 2 in fields; 2 in the middle of the forest (certainly under-represented from lack of forest surveying); the rest on forest edges.

  35. Number observed: 1

    Details: Heard calling and briefly seen in weedy field of tall grass. The field in question is a traditional location for this species during migration.

  36. Number observed: 4
  37. Number observed: 12

    Details: Small numbers in small group

  38. Number observed: 3
  39. Number observed: 5
  40. Number observed: 2
  41. Number observed: 20
  42. Catharus sp.

    Number observed: 1

    Details: Seen briefly feeding on berries at dawn. Looked good for Gray-cheeked Thrush, but fleeting and backlit views meant that Hermit could not be ruled out.

  43. Number observed: 110

    Details: Estimate. Surprisingly small number, roughly 10 birds, on property. Most seen migrating well above the canopy.

  44. Number observed: 1

    Details: Heard from trees.

  45. Number observed: 2
  46. Number observed: 27

    Details: 4 clearly flying overhead, the rest on active within the property, most foraging, including 10 in a grassland pollinator field.

  47. Number observed: 7

    Details: All in flight, ID by sound (although 2 confirmed by sight also). Flying low, often mixed with goldfinch.

  48. Number observed: 253

    Details: Omnipresent throughout the day

  49. Number observed: 81
  50. Number observed: 1

    Details: FLAGGED RARE. Flushed from the edge of a grassland plot with several Chipping Sparrows. First detected by a different flight call: a short-rising chip with an abrupt ending. Overall pallid coloration observed in flight. Flew up to a large tree across the road with other sparrows, but continued "climbing" to high limbs. It quickly flew to an adjacent woodland edge, not to be seen again. Short unobstructed distant views showed overall a buffy plumage from below. Direct frontal view showed warm buffy color limited to the breast. Coloration and vocalization different from Chipping Sparrows, though it was otherwise comparable in size and shape. Facial pattern not seen, due to short encounter and because the bird was high in the tree. Lack of striping below and buffy coloration differentiate from other sparrow, except Ammodramus. From Ammodramus, by size, shape, and flight call note.

  51. Number observed: 2
  52. Number observed: 12
  53. Number observed: 3
  54. Number observed: 285
  55. Number observed: 15
  56. Number observed: 219

    Details: FLAGGED AS A HIGH COUNT. A detailed count of 219 song sparrow. Both observers agreed on counts at each of the 15+ fields survey, and number were deemed both meaningful and conservative.

  57. Number observed: 3
  58. Number observed: 214

    Details: FLAGGED AS A HIGH COUNT. A detailed count of 214 swamp sparrow. Both observers agreed on counts at each of the 15+ fields survey, and number were deemed both meaningful and conservative. One partially leucistic individual with a bizarre, piebald appearance was an unusual surprise. Vocalizations and overall structure helped to identify this unique bird.

  59. Number observed: 16
  60. Number observed: 8

    Details: Small number Foraging in fields. Not including at least 12 overhead.

  61. Number observed: 25

    Details: FLYOVER. 1 flock.

  62. Number observed: 120

    Details: FLYOVER. 3 flocks.

  63. Number observed: 1

    Details: FLAGGED RARE. Overall olive warbler with gray head. Whitish around the eye, blending with eye line that did not extend behind the eye. Thin and pointed gray bill. Blurry streaks on breast (greenish yellow below, with streaks in a darker shade). Spotted and ID by Tim, but seen well by both observers. Feeding in native grasses in walled garden. Tame bird, that calmly returned to feed in the grasses once we passed (heard vocalizing -call)

  64. Number observed: 6
  65. Number observed: 1

    Details: FLAGGED RARE (late). Feeding in tree hedgerow with a fixed flock of migrants, and seen at close range with 8x binoculars. Frantically feeding warbler (typical of species) with diagnostic fanned dark tail with bright yellow areas in outer tails feather (yellow spot starting middle of tail and up). Seen well by both observers.

  66. Number observed: 1

    Details: FLYOVER. Fairly high overhead ID by buzzy flight call, extensive yellow below, and back tail tip (black on distal half).

  67. Number observed: 3
  68. Number observed: 5

    Details: Individuals not seen well enough to ID to subspecies

  69. Number observed: 12

    Details: Good numbers of Palms today after two nights of sustained NW winds. Several individuals were seen well enough to discern browner coloration than the Eastern birds that outnumbered Westerns today

  70. Number observed: 28

    Details: Good numbers of Palms today after two nights of sustained NW winds. Most birds seen well were Eastern individuals, with bright yellow underparts

  71. Number observed: 2
  72. Number observed: 24
  73. warbler sp. (Parulidae sp.)

    Number observed: 8
  74. Number observed: 1

    Details: FLAGGED RARE (late). Fascinating whistled flight call vocalization heard in the dark at dusk for several minutes. Territorial male was heard all summer at that location (co-incidence?).

    Media:
  75. Number observed: 9

    Details: Under-represented from lack of forest surveying.

  76. Number observed: 1

    Details: FLAGGED RARE. Heard only along the edge of the forest and the fields late in the afternoon. Twice gave diagnostic flight call, a strong buzz lower than that of Indigo Bunting but higher than that of Dickcissel. It sounded like the bird was perched relatively low in the trees

  77. Number observed: 8

    Details: Largest group was 4. Drop from 31 counted on September 30. Past peak now.

  78. Number observed: 1

    Details: FLAGGED RARE. Extremely dull bird, likely a first year female. Overall beige colored. Identified from sparrows by bill shape (strong and relatively long- not conical), wide beige eye-ring, strongly black- striped back, and relative size (like a large sparrow). Clean pale throat. Observed for a couple minutes a close range (80 feet), with unobstructed view, with 8x binoculars. Seen well by both observers. Bird was feeding in native grass field edge.
