Antelope Valley Raptor Search Trip Report, 1/14/17

January 21, 2017

After the recent rain and wind storms in LA, we were delighted to find that the weather in the Antelope Valley was ideal for our raptor search.  It was cold but the skies were clear and the winds were calm as we exited Hwy. 14 on Palmdale Blvd.

After a brief stop near the 14, we went east on Palmdale Blvd and then north on 10th St. E.  When we reached Rancho Sierra Vista (Ave. P), we turned east.  Although there were numerous puddles of water beside the road, the uncultivated fields looked dry and we did not see many birds along the road.  Our first stop was at the Desert Aire Golf Club.  As we got out of our cars we were a bit disappointed to see that the Club grounds were quiet.  A Loggerhead Shrike perched on a Joshua Tree across the road drew our attention to the undeveloped land on the north side of Sierra Vista so we crossed the road and began scanning the area.  We saw some of the expected species such as White-crowned Sparrows and then we spotted 2 Cactus Wrens moving around in a Joshua Tree.  They were very active so it wasn’t easy to get scope views but were able to see them with our binoculars.  At one point, one of the wrens landed on the ground in the open, giving us clear views of its peach-colored flanks.  A Verdin appeared briefly and many of us were able to see it as it moved away.

As we went back to our cars, we spotted a Red-tailed Hawk carrying a stick into a nest in one of the trees on the Golf Club property.  It looked as if the nest was the same one we saw being “remodeled” by a pair of hawks when we stopped by the Golf Club during last year’s raptor trip.

When we left the Golf Club, we turned north on 40th St. E and stopped to scan the fields.  We saw a few Horned Larks, some White-crowned Sparrows, a large number of House Finches and the first Mountain Bluebirds of the day.  The sun was behind us and the bluebirds were stunning in the morning light.

We finally tore ourselves away from the bluebirds but we pulled onto the shoulder almost immediately because we surprised to see some Bufflehead and 3 American Coots on a small artificial pond on the west side of the road.

Our next stop was alongside the road just after 40th St. E turns right and becomes Ave. N.  In past years we have seen large flocks of Horned Larks on the sod fields.  This year we saw a single California Gull, some Common Ravens and large flock of Horned Larks in the distance.  Unfortunately, they were too far away for good looks.  The sight of a small V of Canada Geese flying overhead was not unexpected but the “ringer” in the flock certainly was a surprise: a single Snow Goose was flying with the Canada Geese.

We turned north on 50th St. E.  After we drove passed an American Kestrel that was perched on a power line we decided to double back because the views would be better if we approached it from the south.

When we reached Ave. L, we turned and drove east, passing a Red-tailed Hawk that was perched on a telephone pole near the corner.

There were Western Meadowlarks and Brewer’s Blackbirds in the fields and House Finches in the trees along Ave L but the best bird was a Ferruginous Hawk, our first of the day.  It flew away before we could get scope views but it was a good omen for the day.

We turned around and went west on Ave. L, crossing 50th St. E with the intention of scanning the fields along that portion of the road.  We didn’t get far, however, because we noticed a Prairie Falcon perched on a telephone pole.  It flushed from its initial perch but only flew a short distance before perching again.  Once it had settled, we quietly got out of our cars for scope and camera views.  The light was perfect because the sun was behind us and, although the bird watched us, it did not flush so we were able to see it very well.

That Prairie Falcon prompted us to look for more Ferruginous Hawks so we left the area and drove northeast toward the farms that are east of 110th St. E north of Ave. J.  This has been a reliable site for wintering Ferruginous Hawks in past years.  After we crossed 110th St. E we drove east along Ave. J so we could scan the telephone poles along the road and look into the fields from the south.  We saw several Ferruginous and Red-tailed Hawks, though the fast-moving traffic on Ave. J made for less than perfect viewing conditions.

After we had scanned the fields and poles, we decided to get away from the traffic and view the farm from the north so we drove around the block and stopped along Ave. I.   We saw several Ferruginous and Red-tailed Hawks, a number of Common Ravens, another Loggerhead Shrike, and some White-crowned and Savannah Sparrows.

By then it was after 12pm so we headed to Apollo Park for lunch.  While we were driving, some of us got a quick look at a female or immature Northern Harrier that was flying over one of the fields.  It flew out of sight so we kept going.

We ate lunch while keeping an eye on the birds, which included typical park birds such as Mallards (some of which appeared to be hybrids), Canada Geese, American Coots, Brewer’s Blackbirds and House Sparrows.  We saw one Ross’s and one Snow Goose, some Northern Shovelers and a few Ruddy Ducks and a single American White Pelican.  There were very fewer passerines than in past years but we saw or heard some Yellow-rumped Warblers and a pair of Great-tailed Grackles stayed close to the picnic tables.

After lunch, some of us decided to bird along Gaskell Ave. which, despite a recent decline in habitat quality, has been a wintering site for Ferruginous Hawks and other raptors and we were not disappointed.  We found another Prairie Falcon (which flew away as our cars approached) and 3 Ferruginous Hawks, one of which puzzled us at first.  It was perched facing us with only the breast and head visible.  We stopped to look, viewed through the scope and discussed the ID.  After a few minutes, we walked slowly toward it and, in the end, were able to identify it as a pale-morph immature Ferruginous Hawk.

While we were standing near our cars, we saw a number of birds, including Mountain Bluebirds, Savannah Sparrows, House Finches and the only Red-winged Blackbird of the day.  We also watched 2 Coyotes that were moving around in one of the fields.

In the end, it was apparent that bird numbers and species diversity were low but we had excellent views of many of our target species and there were several memorable sightings that made this a rewarding trip.
