crow roosts; Sweetwater Reservoir, woodpeckers

crow roosts; Sweetwater Reservoir, woodpeckers
By {authorlink} – 5:02 am

County-wide, the two largest currently known crow roosts are the perennial ones at the Plaza Bonita Mall area and immediately east of Lake Hodges, on the east side of I-15. Another large roost of ca. 2000 birds was found by Barbara Wise back in February 2018 in northern Oceanside, just west of Highway 78 X College; but its current status is unknown. The roost alluded to by others in posts yesterday in the Miramar area is in fact located in a riparian swale next to the Miramar landfill on the north side of Highway 52, and it has been active for quite a few years, although it is not as large as the others just mentioned. I am unaware of a current active roost at UCSD. Also of slight interest is the discussion about crows being willing to cross major bodies of water. It is my understanding that they are indeed loathe to cross such “barriers,” whereas ravens are not as concerned, which is perhaps why a fair number of offshore islands have been colonized by ravens but not by crows.
Yesterday at Sweetwater Reservoir, there were continuing high counts of 136 Greater White-fronted Geese, 11 Cackling Geese, and 22 Bonaparte’s Gulls; as well as 1 continuing Snow Goose and 2 continuing adult Bald Eagles. A couple thousand waterfowl overall. Large amounts of water are being added to the lake, so the shorebird habitat has disappeared, alas.
At Santee Lakes yesterday, in addition to the continuing Lewis’s Woodpecker at Pond 5, there was a Red-naped Sapsucker in the upper northwest corner of the campground, above the ponds.

Wood thrush has moved to near signpost #9 along the Weir Trail. 8:00-9:00, when I left. Happily foraging in the stream bed. Almost no people here and the bird is not being as skittish as on the weekend.
Thanks to the coterie of birders who pointed it out.

Add another White-throated Sparrow to the county count for this fall. I
currently have one feeding with the White-crowneds in my backyard in
Sabre Springs. New yard bird and new bird for my 5MR.

There are a number of nocturnal crow roosts scattered around the county at this time of year, but the one at the Bonita Plaza shopping mall in Bonita is especially impressive. My estimate this morning is 4,000 birds. Many of them roost at the actual mall but an even larger number are in the bordering riparian along the Sweetwater River. This really is impressive to see it and I suppose is reminiscent of the movie “The Birds” on steroids. Best time to be here this morning was between 6:00 and 6:20 a.m., although it’s overcast so on a clear day it might be a few minutes earlier. One good vantage point is standing in the parking lot in front of the JCPenney store on the I-805 side of the mall. And even though crows are not the favorite bird of almost all of us, this really is quite impressive and worth seeing, and also would be a good lesson in estimating bird numbers!

I live in the general neighborhood, and the evening flight into the roost is also impressive.

Update on the Wood Thrush. I’m not sure what time the last sighting
was this morning by the culvert, but as far as I know it did not go
back there for the rest of the day. I got there at around 8:30  and
was told it had been 20 minutes or so since anyone had seen it by
the culvert.

Later in the morning, not sure what time, maybe 9:30-10:00, David
Trissel found it in the creek bed all the way down by Doane Nature
Trail marker 9. Those of us that still hadn’t seen it hung around
that area for a while and then gave up and dispersed.  Some watched
for a while by the culvert.  Jan Nordenberg and I went back to the
marker 9 area and walked up on the Thrush in the creek bed, but it
quickly moved and disappeared on the far side of the creek. That
might have been around 11:00, not sure. Around 11:50  I spotted it
again in leaf litter about a third to halfway up the far side creek
embankment, and a few others saw it before it disappeared. Over the
next few hours it was seen in the creek bed a few times and also up
the far embankment after it left the creek bed. I have some bad
photos with times of 2:17 and 2:19 p.m. from the creek bed. I know
it was seen at least one other time before that in the creek bed.

Nobody ever found it again by the culvert as far as I know. A few of
us think it’s possible that sometime after 2:30 it may have headed
back upstream, but we never got a clear look at what we saw moving
in that direction. We watched carefully as we walked back and I
stood by the culvert for a little while, but never saw it. So maybe
it will appear at the culvert again first thing in the morning,
maybe not. Not an easy bird after early morning.

The Pacific Wrens were active on and off for a lot of the day. Heard
one at marker 9 multiple times, but couldn’t spot it. Some of us got
good looks at one by the creek crossing that is further down the
trail from marker 9. Matt had one of them near marker 7. Hard to say
how many there are. Definitely more than one. Someone thought maybe
as many as four.
