#2: 3/3/12 @ 8:24pm                                       4/3/12 – Nicasio (Nic) @ 1:03am (12 hours Pip to hatch)
#3:  3/5/12  between 7:30 – 11:15am                4/5/12 – Alex @ 10:17am (approx. 17 hrs. pip to hatch)

#6: 3/11/12 – between 7:52 & 8:15pm              4/11/12 – Tracker @ 1:30am (31 days)
We lost Tracker at the age of  11 days on 4/21/12. With 6 owlets to feed Pepper started hunting and although she tried to feed all, little Tracker was just not able to get enough food.
Alone: 4/18/12 Pepper starts to hunt. She still stayed in box during the day until 4/26/12
Banding: 5/12/12 all owlets banded on right leg
Ages @ time of banding:
 Leap: 43 days old (6 weeks, 2 days)
Nicasio: 40 days (5 weeks, 5 days)
Alex: 38 days (5 weeks, 3 days)
Maggie: 37 days (5 weeks, 2 days)
Mark: 35 days (5 weeks)
Banding information from Anne Ardillo:
owl #1 band number 117761830, 657 grams (bigger legs so got a bigger sized band)
owl #2 band number 117761831, 617 grams (bigger legs so got a bigger sized band)
owl #3 band number 190700152, 567 grams
owl #4 band number 190700153, 582 grams
owl #5 band number 190700154, 662 grams (we think this may have been the biggest bird)
because they are not fully grown, all other typical measurements were not done (wing, tail, beak and hallux claw)..its hard to age just by weight.
Maggie Rufo: They were all very healthy and of good weights. The box was pretty full of stuff and their feet were really gunked up. Anne checked them over carefully to make sure there were no sores on their feet. Sometimes in boxes where the owls are sickly, it gets very wet inside from their sickly droppings and then they develop sores on their feet and need to be treated, but these guys were in good shape.
Fledge Dates & Ages  (first time out of box)                  Full Fledge dates (completely gone)
Leap: 6/1/12 – 64 days old (9 weeks, 1 day)                      Leap: 7/6/12
Nicasio: 6/1/12 – 60 days old (8 weeks, 4 days)                 Nicasio: 7/6/12
Alex: 6/3/12 – 60 days (8 weeks, 4 days)                           Alex: 7/7/12
Maggie: 6/5/12 – 61 days (8 weeks, 5 days)                       Maggie: 7/7/12
Mark – 6/10/12 – 64 days (9 weeks)                                   Mark: 7/10/12                           
**12 weeks (84 days) owlets are considered adults – All 5 of the Nicasio Clutch were 14 weeks (Mark 13 weeks) when they left home.
***7/10/12 Salt and Pepper have returned to the branches of the owl box, guarding home!

  2011Clutch


Courtship started Beginning of February: First gift (gopher) delivered by Salt to Pepper on 2/7/11 in the owl box. 



 

Eggs Laid:  5 total

#1: 2/22/11 @ 3:54pm     Pip in egg on 3/24 (30 days)     Hatched: 3/26 @ 6:34pm = 32 Days
#2: 2/24/11 @ 2:31pm     Pip in egg on 3/26 (31 days)     Hatched: 3/29 @ 12:19am = 33 days
#3: 2/26/11 @ 5:35pm     Pip in egg on 3/28 (32 days)     Hatched: 3/31 @ 6:51pm = 33 days
#4: 3/1/11 @ 11:26am     Pip in egg on 3/31 (31 days)     Hatched: 4/02 @ 6:20pm = 32 days
#5: 3/3/11 @ 4:43pm       Lost on 3/11/11 (See *)
* Egg #5 lost at 6:20am - Pepper somehow had the egg in front of her foot where the leg of a gopher was draped over it and being held there by her foot. Every time Pepper tugged on the tough meat, the gopher leg slammed down on the egg - eventually causing it to crack. Pepper consumed it.



Names:  On April 28, 2011, the students of Nicasio School named the owlets after players from the 2010 World Series Champions, San Francisco Giants Baseball Team.

Owlet #1: Posey
Owlet #2: Lincecum
Owlet #3: Cain
Owlet #4: Torrez **

** After several days of Salt not being around and Pepper not being able to feed the owlets herself: HOP and Wildcare graciously intervened (in case something happened to Salt). They removed Torrez who was substantially weak and dehydrated. They also supplemented the remaining owlets with 24 or so mice. Torrez was taken to the WildCare facility, where they treated and cared for little Torrez the best they could. Unfortunately he was just to weak and passed away on April 24, 2011 at the age of 3 weeks.
After supplementation the other three owlets thrived and Salt was back (all was good).

NOTE: A very special thank you and kudos to all the volunteers who coordinated and allowed the intervention: Principal Christy Stocker, H.O.P. Director Alex Godbe, Maggie Rufo, Mark Tong. The volunteers from WildCare and especially Anne Ardillo and John who gave up their Holiday time to do the field work. ♥
*** Please note that intervention is not usually done, and not always in the best interest of the owls. In the wild  this is all part of nature. It all boils down to "survival of the fittest".

Alone: On May 2, 2011 Pepper leaves the owlets (roosts close by outside the box). The owlets ages: Posey 37 days, Lincecum 34 days, Cain 32 days.

Banding: took place on 5/8/11:
Posey: banded on left leg          Lincecum: banded on Rt. leg            Cain: banded on Rt. leg
            Weight - 739g                              Weight - 689g                          Weight 569g
             Age: 43 days old                         Age: 39 days old                      Age: 37 days old

Fledge Dates: Posey on 5/29 - Lince on 5/31 - Cain on 6/2.  **Empty Box: on 6/12/11

Owlets Became Adults: (12 weeks old) Posey on June 18, Lincecum on June 22, Cain on June 24.        

Salt and Pepper return to the box on 6/22: They are chasing and vocally warning the offspring to stay away. They still allow Cain, but if they are on the branches around owl box and Cain comes, the parents immediately leave. At this time Cain was still being fed.
  *Cain finally made it to FULL fledge on 7/4!!! At which time he received the last delivery of a gopher by Salt.

**Salt and Pepper have been at the owl box every night since Cain's fledging. They have each been inside the box (separately); doing all the courtship type things. Have been bonding on the branches, but NO mating (although Salt has tried). No gifts either. A lot of vocalizing, to/at each other, and at their offspring I believe.  If any turn of events, I shall add.

2010 Clutch






Most of you already know that the Owl Box at Nicasio School was set up in the spring of 2007 by "The Hungry Owl Project", otherwise known as HOP. Two barn owls were sited around March? of 2009.  Hop was notified, and the children at Nicasio were able to see the broadcast of the Owls that took up residency. The IT guy (Mark) decided to broadcast for all to see and it just took off from there. A few of us got to see the egg laying and hatching, etc. We all were writing in the comment section of Ustream what we saw, the egg laying, Salt bringing Pepper food, hatching...the whole nine yards. As you know Ustream  has changed the format and I believe those comments are lost.  Of course we do have the info. on the egg laying and hatching; also I have a list of the rodents that were delivered from hatching to fledging (not total - some were missed) but a pretty good idea.

Ginger (egg #1) laid April 4th @ 1:30pm; hatched May 8th @ 6:28pm

Cinnamon (egg #2) laid April 7th @ 10:30am; hatched May 9th @ 2:33pm

Peppermint (egg #3) laid April 9th 12pm-4pm; hatched May 10th 11-11:30pm

All Three Owlets downed first whole mouse at 10/11 days old.  

TOTAL FOOD DROPS: 310 (known) RODENTS DELIVERED - consisting of: 288 pocket gophers,  10 mice, 8 voles, 1 mole, 1 rat, 2 rabbits  ** This count was taken from May 9, up to  July 3o, 2009 **
