Sevenmile Creek bird monitoring survey. 42 F to 46 F: a warm and blustery day! Weak sun at the start with 90% high stratus clouds and gentle W breeze, gusting to moderate after 1023. By 1025, sun became full. Breeze began gusting to fresh around 1104, then gusting to strong by 1122. Sun was mostly obscured between 1130 and 1230, then again between 1320 and 1350. Cover of high stratus varied considerably during the survey, between 90% and 40%. The snow was ca 6 cm deep at the start of the survey, melting substantially and decreasing to 2 cm at the end; cover decreased from 95% to 60%. Ponds were 100% frozen except for the seep at the E edge of the new channel section, and 1 small round hole in one pond. Standing water on top of the ice in 2 ponds later in the survey! Notably less snow cover in the disturbed part of reach 3: about 1/2 totally bare ground, a stark contrast to adjacent areas with grass cover that evidently prevented the snow from drifting so much. Other parts of reach 3 were covered in ice/snow - from stream overflow? Lots of puddling and mud in reach 3.

Bird notes: Notable increase in ATSP activity and number compared to recent surveys - very interesting to see them apparently foraging for invertebrates near the stream. Numbers of RLHA sightings notable, as well as BAEA - no NOHA or RTHA (though I saw an adult light RTHA at 1447 after the survey, flying low E of Head Ln and then over the sewage lagoon area). SOSP and TOSO both expected, but notable detections nonetheless. Surprising lack of CORA activity, except for 1 unidentified CORA/AMCR flyby. Lots of BBMA activity, a substantial increase, perching in the riparian shrubs - gearing up for nesting? No MALL seen, nor tracks. Weather and site conditions reminded me of March - will WEME and MOBL be early this year?? Half-expected to see them today, but that's probably very unlikely until photoperiod increases more. Possible HOSP notable. Still no carduelid finches since the last goldfinches in December.

Observations

  1. Number observed: 20

    Comments: Including 18 *beyond property boundary* (the other 2 flew over, at 1123, heading S/SW over reach 3 at ca 2x shrub height). At 1143, counted at least 20 ROPI (by 5s) in low flight over houses and trees SW of reach 3, across Birdseye Rd. Around 1326, saw 1 ROPI in flight N of reach 3.

  2. Number observed: 1

    Comments: From 1208-1212, while at the constructed wetland, saw an eagle at moderate height (ca ht of Scratchgravel peaks or a bit lower?), first way upstream, then approaching, then passing overhead and continuing to the south. Circling and gliding with very few flaps.

  3. Number observed: 4

    Comments: 1 seen distant at 1008 in low flight, apparently hunting, over the S-sloping hill N of the stream in the W part of reach 4. At 1048, saw a light immature in flight over the E part of reach 4, circling higher, not clearly hunting now. At 1107, saw an adult light RLHA in flight over grassland N of the photopoint, beyond the property, circling moderately high and then descending and hovering (photos - this one with a solid black belly band). At 1145, saw 1 in flight N of reach 3, past the property, over grassy hills in low flight, facing into the wind and remaining motionless, hunting. 1221-1227, saw a light (adult?) and dark immature RLHA in hunting flight and hovering over the field and stream in the general area of the cross-fence. Photos of both; the light one landed for a minute or two on a fencepost south of the stream. From 1324-1329, an adult light RLHA (DIFFERENT from the individual seen at 1107 - this one with a light belly) seen hovering and gliding and pointing into the wind and staying motionless, hunting over the grassy hills N of the reach 3, on the property and then beyond it.

  4. Number observed: 9

    Comments: Including 4 *beyond property boundary*. At 1105, 2 BBMA flew upstream silently and low past the photo point, landing briefly in shrubs there. Between 1120 and 1123, at least 3 BBMA took off from an area of somewhat dense Prunus virginiana beyond the E end of the new stream channel in reach 3. Possibly investigating nest sites? Saw up to 4 BBMA perched in riparian shrubs on the property at least 4 other times in the survey, a notable change in activity. At 1239, a Coyote flushed from grassland 50 m from me and ca 50 m S of the property corner of the cross-fence, a bit E of the fence - crossed the fence and went SW, disappearing into riparian shrubs. A nearby magpie called right after the Coyote flushed. Ca 1410, 3 BBMA flew E from a Russian-olive row in the W part of the sewage lagoon area- suspected they were eating the fruits.

  5. crow/raven sp.

    Number observed: 1

    Comments: Ca 1208-1209, flew upstream silently past me at ca 2x shrub height. Wings seemed lanky like CORA, but overall seemed small, and small-tailed. Nonvocal. Very likely CORA at this time of year, but my initial impression was AMCR and I wasn't able to confirm either.

  6. Number observed: 2

    Comments: After ca 1033, a single BCCH associated loosely with a few of the ATSP flock, making "chickadee" calls. Ca 1110-1115, heard and saw at least 4 ATSP along the stream ca 50 m upstream of the photo point; briefly heard a BCCH farther upstream. Ca 1152, heard and saw 2 BCCH in shrubs along the stream ca 150 m above the diversion; they moved upstream. At 1250, saw 2 BCCH moving through shrubs near the turnaround. From 1345-1348 near the photo point, observed 1 ATSP flitting on the snow at the edge of the stream, apparently foraging. Then 2 BCCH moved ca 50 m upstream from the same vicinity; watched 1 branch-gleaning in a small Alnus incana. Then saw a SOSP apparently gleaning or at least hopping around briefly on a shelf of snow/ice at the edge of the stream.

  7. Number observed: 1

    Comments: Just one sighting during the survey. At 1202, flew rapidly past me, NE of the constructed wetland, riding the tailwind. Perched in the top of a shrub briefly; I glanced away, and it apparently flew on.

  8. Number observed: 9

    Comments: From 1030-1042, observed at least 6 ATSP along the stream and in the surrounding area in reach 4, centered ca 50 m below the red culverts. Observed birds perching in Alnus incana, Elaeagnus angustifolia, Acer negundo, Prunus virginiana, and Salix exigua; got to see 1 bird closely along the stream, where it perched on the snow, apparently foraging for something, rather actively. Also observed 1 bird fly down to the stream where a small A. incana branch dipped into the water; it dipped its bill in to drink and then bathed, getting ca halfway submerged and shaking (photo!). After ca 1033, a single BCCH associated loosely with a few of the ATSP flock, making "chickadee" calls. The ATSP made frequent "tip" calls; no "swilit" warbled calls.
    At 1055, ca halfway between the red culverts and the photo point, saw 1 ATSP along the stream. Flushed up to perch on a branch, then down to the snow, where it moved around and apparently foraged. Acted a bit flighty, rather like foraging TOSO when going after inverts.
    At 1101 at the photo point, heard "tip" calls from at least 2 ATSP.
    Ca 1110-1115, heard and saw at least 4 ATSP along the stream ca 50 m upstream of the photo point; briefly heard a BCCH farther upstream. Observed 1 ATSP ground-gleaning near dead grasses at the top edge of a vertical bank, near the edge between snow and bare ground.
    From 1120-1136, counted at least 9 ATSP in the E part of reach 3 near the stream. Observed 1 foraging on the snow near the stream - saw it dark after and successfully capture a small flying insect (apparently dipteran). Then briefly saw a SOSP appear right at the edge of the stream - observed an agonistic interaction between it and 1 foraging ATSP. They faced each other within cm, then the ATSP flew away. Ca 1215 or 1220, a bit upstream of the rocky draw, heard a "tip" call from an ATSP somewhere along the stream.
    At 1338, heard 1 ATSP in the east half of reach 3.
    From 1345-1348 near the photo point, observed 1 ATSP flitting on the snow at the edge of the stream, apparently foraging.

    Number observed: 2

    Comments: Ca 1200, heard what sounded like HOSP "cheerp" calls twice near the constructed wetland and glimpsed 2 large sparrow size birds in the top of an alder along the stream. Flew before I could ID them: was not able to rule out GCRF, whose calls can sound somewhat similar to HOSP.
