Lakota Day 1

Lakota, a juvenile broadwing, was trapped at Poison Oak blind at 1118 hours. She was released from the top of Hawk Hill at 14:30 and proceeded to fly 25 feet down the hill to a coyote bush, where everyone could see her!  She stayed there for about an hour and a half, then flew to the north side of Hawk Hill and stayed there for about 15 minutes, then flew back to the east side of Hawk Hill. Lynn kept track of her there until approximately 1600 hours, then determined that she had moved down into Kirby Cove. David and Lynn took some bearings from either side of Kirby Cove, while James took a bearing from closer to the bridge back into Kirby Cove.

The kettle of Broadwings (plus a couple of RTs, and several TVs) merged, split, re-merged, split for several hours. Allen pointed out to me two dark morph Broadwings that were part of the kettle.  According to Lynn, none of the Broadwings seemed to cross and that included Lakota. The thermals seemed to evaporate over the gate, and then the kettle would return to Slacker Ridge or back towards Hawk Hill. It was an ever changing dance, and Lakota was having none of it.

This morning the fog has cleared and this might allow the BWs to cross, and that includes Lakota! Keep your bins up!

Telemetrists Phil and James will be out for the duration. Larry and Barb join in on Monday, as well as apprentices Richard and David. Lynn, who’s usually home base, just had to get back out there!  So I will try to keep you all updated with the Lakota’s progress towards the border.

September 29, 2012

Well, we're back in the saddle, again.  This morning the fog was hanging on Hawk Hill, but it was significantly lighter that Friday's Fogged Out day.  We headed up Conzelman to beat the crush of birdwatchers (who wanted to see an amazing flight of Broadwings) and tourists who just wanted to see the City from a beautiful spot.

By 11 AM, Hawkwatch "officially" began the count as the sky cleared.  I could "hear" the banders chatter on the radio.  "Three Broadies between Slak and Poak".  "How do we catch these things?"  Eighteen minutes later, "POAK to Telemetry" comes across the radio.  You've got to be kidding!!!  Quick calls out to the team members (we're a skeleton crew today, but should be at max by Monday).  Amazement was everyone's reaction.  Will Telemetry ever recover from 2 Broad-winged Hawks within 2 weeks?!!  We waited 18 years since Zoe, and now we've added Marathon and now Lakota.  Wow!!

Okay, so maybe the fog kept Lakota from resuming her southern movement, but this won't last forever.  Wait to see what happens tomorrow.

Oh, and by the way, I will be hitting the road, too.  We were a little short handed today, so I packed a bag..... and since I have my bag packed, I might as well keep going.  BUT, it will be hard to keep up the Blog while on the road.  Maybe someone will help.........?

Sept 21 -- An Unbelievable Day!

The luxury of having four teams out tracking is about to come to an end.  Many of the trackers have been out since Monday and will be returning home today. 

Two teams were placed along the peaks north of the LA Basin in order to pick up Marathon's signal as early as possible.  The other two teams worked peaks and ridges to the south of where they believe Marathon was located. 

Bingo!  By 12:30, Marathon was clearly below the crest of the mountains and Mt. Wilson lost the signal.  The two northernmost teams began their long journey home to Marin, Alameda and San Joaquin counties.  Bill and Mike, on Elsinore Peak continued to record Marathon's movements while Phil and Linda were likewise busy on the San Jacinto Ridge. (These two locations were critical in determining Zoe's flight path).  Marathon flew close enough to the San Jacinto Ridge that the team there was able to clearly hear her signal with the attenuator "On" (remember that little gadget which suppresses the signal so that only nearby signals are picked up).   Phil and Linda decided to head down to Laguna Mountain, which is 20 miles north of the border with Mexico.  Phil  wanted to "hear" Marathon as she crossed the border.  As they traveled on Hwys.79 and 371, they continued to pick up her signal.  Unfortunately, Phil's car does not have air conditioning; therefore, Linda had to hold the receiver to her ear to hear the signal over the wind noise!  And occasionally, they would pull over and take a bearing. But it all worked!

As Phil and Linda climbed up the road to Laguna Mt, the signal was crisp, clear and definitely "chirping" away.  From approximately 3:45 to 5:45, they listened to the signal fade and return, first soaring then circling, back and forth.  Phil said you could interpret Marathon's movements with such an active signal.  Phil felt by the end of the day that Marathon was probably across the border.  At the least, she was very close to the border; however, without a crossbearing we can't mark the time when she crossed.

It's been 18 years between Zoe and Marathon's flights were tracked by the GGRO Telemetry Teams.  This year we had the luxury of being able to have 4 teams in the field for several days.  In 1994, we only had 4 - 5 trackers out, in total.  This year a total of 10 individuals were involved in tracking Marathon.  There were some similarities, but there were also many differences in the flight paths of Zoe and Marathon, and they will be interesting to compare.  Now we'll move into the data analysis phase.  But no matter which path they took, in each case, there were 4 travel days between being banded and tagged in the Marin Headlands and crossing the border into Mexico.  Marathon still has a marathon journey ahead of her. 

Best wishes for a safe journey. We're going to head northward to sleep.

Sept 20 -- Crossing Mountains

What a day the trackers had today!  Marathon was very elusive today.  With four teams on high points, Marathon turned into the mountains, crossing the Carrizo Plains and heading to the eastern side of the Sierra Madre Range.  The last bearing was from Frazier Peak and pointed in the direction of Santa Clarita (but, of course without a crossbearing we really don't know where to put a dot on the map). 

The interactive map on the Parks Conservancy website is not able to keep up with the trackers.  Or maybe, I should say that the trackers are so tired by the end of the day, that they have felt sleep was preferable to giving me points to put on a map. (When the teams return, we will be able to plot in detail and fill in the dots). Marathon is not making this job easy! 

Marathon also seems to be a little behind Zoe's pace (BW, tracked in 1994).  Some teams must end their tracking on Friday, but where will Zoe be?  Will she be at the border by Friday night, as Zoe was, or will we be short teams on Saturday?  A call has been placed for possible help needed for the weekend.

Marathon Discusses Her Journey with Chris Briggs, Sept. 17, 2012

Sept 19 -- End of Day Summary

As you know we had teams spread out on high points, and it worked beautifully.  The team on Williams Hill began picking up Marathon's signal around 1000, pointing back towards the Panoche Valley.  At 1123 the team on Parkfield picked up her signal.  By 1330, Marathon was passing Barb and Lorri on Williams Hill, and by 1530 she flew close to the team on Cuesta Ridge, above San Luis Obispo.  (We have a little gadget on the receiver which allows us to restrict the signal strength so that we can tell if the bird is "close")  By 1600 Bill, on Cuesta Ridge, and Phil and Mike on Parkfield Grade, all lost the signal abuptly.  Did Marathon head into the mountains?  Did she go down hunting?  Did she head to roost?  So many questions, but we'll have to be patient and see where she pops up Thursday morning.

Sept. 19 - New Interactive Map

Exciting news!  We've got a interactive map which will show the rough estimation of Marathon's various locations, as she continues her journey southward.  We will not be able to give more exact info until the teams (with their data logs) return home.   Click here to check it out!

Sept. 19 -- Afternoon Report

The team on Williams Hill near Fort Hunter Liggett, and the team on Parkfield Grade both have the signal and report that Marathon is slowly (interesting word for a Broadwing who has so far to go) working her way south between the two teams.  A third team is on Cuesta Ridge (above San Luis Obispo) waiting for her arrival.

Sept 18, Marathon Heads South from the Headlands

Marathon is her own girl, and is not following Zoe's lead from 18 years ago (East Bay, through Salinas Valley).  Of course, maybe she's using Google Maps instead of the AAA maps which Zoe had to use.

Today, we were able to have 4 teams out on Marathon.  Four teams is a bonus since we can have 2 teams on highpoints (in this case, Barb on San Bruno Mt and Cheryl on Mt. Hamilton) and two teams mobile. Phil and Mike began along the East Bay Ridgeline (Grizzly Peak area) and Bill and Lorri were "on the bird" early in the morning.

So, Tuesday morning Marathon woke up and continued her journey southward by heading over the Gate, through the City, and past Barb on San Bruno Mountain.  Bill and Lorri were immediately playing catch up, but were able to get bearings as they also moved down the Peninsula.  Meanwhile Phil and Mike had great bearings as Marathon moved southward towards Los Gatos.  Add in the bearings from Mt. Hamilton, and I think we'll have a pretty good flight path for Marathon through the Bay Area.

Then Marathon flew into/through the Santa Cruz Mountains.  Cheryl, on Mt. Hamilton, maintained the signal for most of the day...... hoorah!  The 4th team was proving very valuable.  The other teams repositioned to Fremont Peak and other nearby highpoints with mobile teams trying to get crossbearings.  About 1500, crossbearings placed Marathon near Panoche Valley. One team traveling the area was unable to pick up her signal within the valley, so Marathon likely moved into the nearby hills.  That was the last crossbearing of the day.

Similarly, when the teams were tracking Zoe in 1994, they would lose her mid-afternoon and then the following morning she would pop up about 40 miles south. Where will Marathon pop up on Wednesday?  We'll all have to wait and see.

Sept. 17, 2012: On Your Mark, Get Set,.........Go!

The 2012 tracking season has begun with Marathon, a juvenile Broad-winged Hawk.  It's been 18 long years since we tracked our first Broadwing, Zoe.  When told that we have a Broadwing, Phil Capitolo simply said, "I'm stunned!"  That elusive Broadwing that we've been waiting for, flew into Hill 88 blind, and was banded by Dick Horn.... on his birthday!  Thank You, Dick for sharing your present.

Soon we'll have a couple of photos to add to this Blog, so stay tuned for daily updates (or as frequently as I can get them posted).

After being released from the road beneath Hawk Hill, Marathon flew directly over Slacker Ridge and settled down on the East side of the ridge, overlooking the North Tower of the Golden Gate Bridge, and Hwy 101.  Tomorrow we anticipate that she will continue her southward journey.  Stay Tuned!
