Ridgway’s Rail Family

This morning (April 24) around 10:40 am I was leading a group of fifth graders along the trail at Buena Vista Lagoon when near the SE corner I heard the unmistakable call of a Ridgway’s Rail. Out popped an adult, followed by 7 black chicks and another adult! Wow what an awesome sight to share with the kids. I hadn’t seen or heard a rail here for over 2 years. Most of the trail is flooded out.

Least Bittern at Poway Pond

I've been to Poway Pond for the last three days, and have heard a Least Bittern singing its cooing song from the reeds at the public pond on all three visits. I heard it between 6:00 and 6:30 pm on Monday and Tuesday evenings, and again at about 7:50 and 8:30 this morning. I managed to get a marginal recording yesterday evening. This morning I got about a 2 second glimpse of it as it flew across one of the few openings in the reeds and then buried itself again.

List from Tuesday evening with recording. Crank the sound way up if you listen to it. The bird isn't very loud and my only recording equipment is my cell phone.

There is also a family of Green Herons on the public pond. I found three youngsters standing either in or near their nest yesterday, along with both adults. Saw the young birds again this morning, but not the adults.

The resident male Wood Duck is also still on the private pond.

Re: Mountain Plover at Saltworks Pond 20

Is there any online source that shows the salt works ponds with their
respective numbers? I have a couple of aerial photos from old salt works
construction documents (retrieved online) that number some ponds but not
others. I know where ponds 10, 10A, 11, and 12 are but not 13 let alone 20.
I assume 13 is south of 12 and adjacent to the Otay River channel? A
graphic at <https://tinyurl.com/y9c3e8u3> labels pond 15 but no others. I
would guess since much of the refuge is currently closed to public access,
USFWS doesn't see a need to disseminate this info. Thanks.

Little stint still present

The breeding plumaged Little Stint, undoubtedly one of the two birds present in November and December last year, continues today in the drying up saltworks pond a third of a mile east of 13th Street. The birds are far away so one needs a very high-quality scope to find it, but because of the overcast the lighting is good still. Once the sun comes out it will be totally hopeless. The bird is in the flock of hundreds of Western sandpipers. There was a first of season Wilson's phalarope here early this morning but it has disappeared.

Mountain plover has flown at least temporarily

Just before 7 a.m. the saltworks Mountain Plover flew south over the bike trail and may have landed in the extensive saline flats and short vegetation that runs between the bike trail all the way down to Palm Avenue, but it is difficult to check there.

Little Stint update (negative)

Soon after posting the news on the Little Stint this morning, I lost track of the bird, as all of the peep close in scattered all around the pond and joined and mixed up with another large group in this same drying impoundment. The grand total of Westerns there is between 1200-1500 birds. Two-thirds remained always too distant to be able to sort through them, given both the distance and the worsening heat distortion. Periodic smaller subsets of up to a few hundred birds would come back close enough to ID and then quickly scatter again, but I never saw the Little Stint or the hyper-rufous Western Sandpiper again. The section where the Little Stint frequented originally was the southwest corner of the pond. As mentioned in my earlier post, this pond probably only has one more day left before it is largely too dry, and even now clearly a lot of the birds remain too far out. Also, anytime in the next week or so should be the major departure of many of the wintering Westerns northbound.  Best bet would be to try late today or early tomorrow morning, to avoid all the heat haze, although the tide will be low in the early AM on the bay, so not all the peep may be on the impoundment then. When I saw the bird today the tide was still somewhat low but fairly quickly incoming.

Again, this bird is almost undoubtedly one of the two individuals that were a couple ponds farther to the west in the saltworks back in (Oct) Nov-Dec.
