Discussion:
     We have had great days and then some lulls. The hawks are pulsing through. Without a steady source of food we are not getting the numbers we usually expect. This implies that hawks are passing through without stopping. Although some hawks are feeding on Flying Ants.The number of hawks should pick up in the following days. Roost sites are split between the old Elis Farm, Date Farm (Evans Ranch) and Roadrunner Club. Although we expect more hawks, we have had around 3,000 already move through the area. We have now surpassed March numbers for 6 of the 15 years of observations.
     Below is a shot of hawks roosting at the Date Farm (Evans Ranch). Someone jumped the entrance fence to approach these hawks and they scattered. Two things occurred-the person that jumped the fence was trespassing and it is a federal offense to knowingly approach threatened birds and disturbing them.
   
Evening Watch:
Only a few hawks came in this evening, Wednesday March 21.

Prediction:
Hopefully there are hawks roosting in outlying areas. The wind should pick up this evening and any hawks will leave early. The expectation of more migrants keeps us coming back every day.

Migration:
Swainson's Hawks-111
Turkey Vultures-18

Discussion:
3/13/18 we had several hawks on the ground. Some were foraging for flying ants. Aerial feeding was also evident. So the mystery is solved. Having ants available as a food source in dry conditions is unusual. Today the hawks kettled up very late as the weather conditions did not favor migration. It was hot with still air. By 10am however the hawks were on the move.

Evening Watch:
This evening only around 10 Swainson's Hawks were observed.

Prediction:
It might be a bit windy tomorrow early so migration may start by 7am.

Incredible Migration Today-March 11, 2018-1,313 Swainson's Hawks

Leader:
Hal Cohen assisted Herb Stone, Judy Davis and John Peterson and many other folks

Migration:
Swainson's Hawks-1,313

Discussion:
At least 12 large kettles formed during a one hour migration. Hawks streamed by continuously. The roost sites included the Date Farm (now called Evans Ranch); The Roadrunner Club; And points out east. The hawks took time to find any air movement. They drifted about to the east until the ground warmed up. Some kettles had a few hundred hawks. I am hoping that folks that took videos will share them. Below are a few shots of the large kettles One shot in particular shows the depth and spiral motion of a kettle.

Evening Watch Monday March 12, 2018:
This evening we were treated to several hawks close and low and in Eucalyptus Trees in the Date Farm. Around 100 hawks settled into the trees. Photo's to appear with the next blog.

Prediction:
With light wind predicted the hawks will most likely take off between 7:30am and 9am. We'll start at the evening site on Borrego Valley Rd. 1.5 miles north of Palm Canyon Drive. We'll move over to DiGiorgio Rd if the hawks move straight west.

March 11-48 Swainson's Hawks

Discussion:
Although slow we are experiencing continued migration. On March 7th the hawks cooperated and flew directly over the old watch site. Roost sites for the 7th and 8th were the Date Farm and Roadrunner Club. March 9the was an interesting day. 24 Swainson's left early with some wind. At 8:30am a large kettle formed over the Date Farm. The hawks moved directly west and provided some good looks from DiGiorgio Rd and Big Horn. Several birds spent some time aerial feeding. We are not sure of the insect id. There is no apparent flying ant explosion. We had some nice small kettles on March 11.

Evening Watch-Sunday March 11, 2017:
This evening well over 350 Swainson's Hawks were spotted at 6:45pm. They apparently descended into the Date Farm-now called Evans Ranch.

Prediction-Monday March 12:
Light wind predicted to lift-off between 8:30 and 9:30am. Best views from the evening site on Borrego Valley and Digiorgio Rd near Big Horn. We should have some spectacular kettles.

A Wonderful Day For Viewing and Photography-March 6, 2018

Leader-Tuesday March 6, 2018

Migration:
Swainson's Hawks-187
Turkey Vultures-17

Discussion:
The number of hawks exceeded the prediction of yesterday evening. Several SW kettles formed from the Date Farm and an area to the south. Also several Turkey Vultures joined the hawks. I've been asked about evening and day numbers. In the evening we estimate the number of hawks flying in. We also establish the prime roost location. The evening estimate is wrong most of the time. Our count Monday evening was off quite a bit (120+observed in the evening). Often after the initial touch down there will be additional hawks, even after we have gone home. This morning I noticed hawks flying in from the east to join the prime group. There are often multiple roost sites in one evening. Today photographers got some great shots of perched birds along the road. Also the kettles and streaming hawks across DiGiorgio Rd were spectacular. The photos below are mine with a small Lumix camera. I am hoping that the number of photographers with real camera's and lenses out there today will share their shots.

I was also asked the question as to why so close this season. Last season we had an abundance of food available and the hawks spent most of there time foraging away from typical roost sites. When they finished feeding they retreated to nearby roosts. These roosts were a distance from the observers.

Evening Watch:
This evening only 8 Swainson's Hawks came in. Of course it's possible we missed some. They may have descended into the back of the Date Farm or the Roadrunner Club.

Prediction:
Wind should be light tomorrow so expect the hawks to kettle up between 8 and 9am.

Discussion:
The season started with a bang-63 SW's. Then we had a slow down for a few days and again a nice count. After a few 0 days we had a fair day then an evening with over 100 Swainson's Hawks. There are also several Turkey Vultures in town.

We are in need of good photos to display on the blog. Send me your photos.

Evening Watch:
This evening, March 5 we had a large kettle of hawks descend into the Date Farm. They remained in the air for almost half an hour to the delight of several onlookers. Some were observed in trees from the entrance to the farm. Over 100 hawks are now in the Date Farm after a great view of the incoming hawks.

Prediction:
Light wind is predicted for tomorrow March 6. Lift-off of probably a large kettle or 2 or 3 will take place between 8 and 9am. Best viewing probably from the evening site.
