Swainson's Hawks in Borrego Springs

Hal Cohen
 

Today, March 28,199 Swainson's Hawks migrated from Borrego Springs. Once again hawks were observed feeding in fields on small grasshoppers. Because the hawks are entering the valley late in the evening, it is hard to predict when they arrive. In fact, we believe that most of the hawks descend after 7:30pm. Tomorrow with winds picking up early, any hawks in the valley will probably continue migration north shortly after sunup. We will be in the field by 6:30am tomorrow. Thus far this season, we have counted 4,376 Swainson's Hawks migrating from Borrego Springs.

Swainson's Hawks in Borego Springs 3/27/23

Hal Cohen
 

Today 273 Swainson's Hawks migrated from Borrego Springs. The location of lift-off was in old potato fields near Henderson Canyon Rd. Yesterday evening we only observed a few dozen hawks coming in late in the evening. I did not send an ALERT as we did not see big numbers, The ALERT is triggered when more than 100 hawks are observed in the evening. This evening we will send scouts to the potato fields to search for incoming hawks. There is now an abundance of grasshoppers in the area. More hawks will probably enter the valley to feast on the insects. So far only a few Sphinx Moth caterpillars have been found. In the coming weeks we expect more hawks.

Mount Soledad morning-flights; miscellanea

lehman.paul@verizon.net
 

It's that time of year again for the potential for spring morning-flights of landbird migrants at the summit of Mount Soledad in La Jolla. Such flights can be very impressive, provide for an extra ID challenge to birders, and are a great way to witness active migration in action. Particularly good-sized flights at this site can be a bit fickle, and one needs a proper combination of overnight and early-morning weather characteristics for a good morning: mostly clear to partly cloudy skies, a wind flow from between the north and east (or east-southeast), and perhaps warmish dawn temperatures. The season runs from now through about the third week of May. Hundreds of birds can be seen in a single two-hour period starting within a half hour of dawn. I'll post 'warning' of a potentially good morning the day before if the weather looks particularly conducive. Early today there were light easterly winds, so several of us were there, right near (just before) the summit, from 6:40 to 8:00 AM. Totals of clear northbound migrants were only mediocre, but sort of what expects in late March: 14 Western Kingbirds, several swallows, 7 American Robins, 26 Yellow-rumped Warblers, and 1 Black-throated Gray Warbler. Numbers and diversity will improve greatly during April. Peak flights often occur during the last 10 days of April and first 10 days of May, but, again, are very weather dependent. Mid-May is also a great time to look for migrating Black Swifts here, but under quite different (and equally fickle) weather conditions.


Also today, 27 March, the Long-tailed Duck and 4 Snow Geese continue on Mission Bay. Yesterday, I had my first Black-chinned Hummingbird of the season, in Tierrasanta, and a wintering flock of 17 Greater White-fronted Geese continued in the Nestor area, as did the wintering Eurasian Wigeon at the J Street mudflats. On the 25th, a wintering Hermit Warbler continued in Serra Mesa, and continuing male American Redstart and several migrant-arrival Wilson's Warblers were near Montgomery Field.

Isn't that photo of a hoary redpoll, not a common redpoll?

Grasshopper Sparrow

Butch Carter
 

Hello
    I am looking for advice on finding Grasshopper Sparrow for my ABA list, Have been planning to explore the "Mission Trails Regional Park -- northeast (dam to grasslands) during the first week of April. I have received emails from the eBird needs list showing that they are there now.
    Is it best to approach from the Mast Blvd Hiking Trailhead or the parking on Father Junipero Serra Trail? Any information would be appreciated.

Common redpoll

Bobbie Stephenson
 

Hi,

I'm reporting that I saw a common redpoll in my front yard (of native plant species and weeds) two days ago.  I was perplexed about what it was because I never expect to see anything unusual.  The red spot on its forehead was distinctive and I know now that is the species I saw.  I didn't get a picture because, at the time, I didn't know what it was and I didn't think it could have been a rare sighting.  I've included a picture with this message of a common redpoll  seen in San Diego in 2012 that was even reported in the Union-Tribune, so they do occur here occasionally.  

Most of you don't know me as a birder, but you might know me as an active member of the California Native Plant Society, San Diego Chapter (CNPS-SD). Since you probably don't know me, I would probably have to have the sighting verified, but I haven't seen the bird since that day.  

It was sitting on a low branch of a wisteria and it was eating seeds from a tall grass species.  It had the very distinctive red spot on its forehead, but no other red or pink on it, and it was streaked on its sides.  There were 4 birds, but I only got a good look at one of them.  They were each smaller than a housefinch but not as small as a bushtit.

This sighting was near the intersection of Sutter and Eagle Streets in south Mission Hills.  All I want to say is, please keep your eyes open for this bird - it is out there!

Birding Is Fun!: Amazing Weekend in San Diego


Swainson's Hawks in Borrego Springs, CA

Today, 381 Swainson's Hawks migrated out of Borrego Springs. This evening only a few Swainson's Hawks were observed entering the valley. Several Turkey Vultures were spotted coming into the Roadrunner Club this evening. We will continue monitoring the migration of Swainson's Hawks until April 15.

Today 182 Swainson's Hawks migrated north from Borrego Springs. This evening a few Swainson's Hawks were observed and 2 Golden Eagles. We do not expect many migrating Swainson's Hawks tomorrow. We will continue to monitor migration through Borrego Springs until April 15.

Swainson's Hawks in Borrego Springs

A nice evening as over 100 Swainson's Hawks covered the northern sky. They descended into a field to the south of West Coast Tree Farm (north of the night site). As predicted they took off and flew almost directly over onlookers at the evening site. Their destination-The Date Farm. More hawks will probably move to the Date Farm in the dark. Tomorrow with a breeze, they might get up by 7am or earlier. Hopefully the wind will not pick up and the hawks may get up later. They might go to ground near the date farm along Borrego Valley Rd. With food in the valley (grasshoppers), the hawks could possibly linger in the valley before departing. 

Earlier oday we had 42 Swainson's migrate along with 4 Turkey Vultures. The SW's spent some time sitting in citrus trees to the north of Henderson Rd. Yes, this is the first time I've ever seen the hawks use the citrus trees.

Sorry all. Bad reception in Borrego, and my eBird automatically grabbed my neighborhood as location. Sorry.

more storm groundings of waterbirds inland

lehman.paul@verizon.net
 

This morning's (21 March) foul (or fowl?) weather grounded quite the collection of interesting waterbirds at inland bodies of water. In addition to the early and exceptional flock of 6 Sabine's Gulls at Lake Murray as reported by Matt S., I hear that David T. had a flock of 10 Brant land at the Borrego Springs settling ponds, Brennan M. had 2 Surf Scoters at Santee Lakes, and Sweetwater biologist Pete Famolaro reports a single flock of 81 (EIGHTY-ONE) Surf Scoters on Sweetwater Reservoir (closed to the public Tues-Thurs).

They have apparently left the lake during a lull in the rain. Probably on their way to the ocean.
