OTHER OWLS ON THE RESERVE, THE NORTHERN PYGMY OWL

As we continue our fall monitoring or NSWO, one other exciting thing about being on the Reserve are the numbers of different species we might detect aurally or visually. Lately the Northern Pygmy Owls (NOPO), a mostly crepuscular/diurnal species has been calling from the trees above our saw-whet nets.
Last night we heard a pair dueting. They are incredibly petite little predators, mostly hunting songbirds, but opportunistic taking small mammals and insects too. I love this video that I found on youtube (https://youtu.be/yoRB3BlT3U0) that shows many of their behaviors . The toot/trill series the owl calls at the beginning is very common with the Reserve owls too.

GOING HIGH TECH WITH A NEW TOOTER- BRINGS IN THE OWLS!

I'll admit we are a pretty low-tech program, except for the Steve King inventions and modifications.  Once again he pulls through with a beneficial addition to our station, this time, a louder broadcast caller to attract owls. Previously our "sound system" was  boombox like this, using a CD of NSWO calls.

For the past 9 years of data collection, our broadcaster.
But now with the Mega Tooter, we can up our decibels and perhaps attract more owls to our station, using and Ipod with owl calls and a rechargeable battery.
The Mega Tooter, designed by Steve King
This follows the Project OWLNET protocol better than we have in the past and increasing the volume was a suggestion by an OWLNET co-founder. So is this what is making our now 16 owl season a success, or is it just a good year for saw-whets? Hard to say, but as the season continues perhaps we will have a better guess. Stay tuned!

MAGICAL OWLS AND CHILDREN - CRYSTAL AND ISABEL

There is something about children and owls. Owls are magical and children connect to that. Isabel came up with her mom and dad Jamie and Jason to learn about our owl research. Jamie the Reserves manager effectively helped promote our continued monitoring of the most adorable owl, the northern saw-whet (NSWO). 
Crystal (the owl), Jason, Isabel, and Jamie 
We were all pretty excited when we banded 7 new NSWO. Isabel named this one Crystal, before she released her (and two others) back into the night. I think her owl encounter will stay in her memory for years to come. That's what we can hope! Thanks banders Navit and Julie, and the Visinoni family for coming to visit us.
Isabel looks on as we read the band number, which identifies
the owl as an individual. In addition to a number, Isabel thought it
was appropriate to give her a name - Crystal

OCTOBER - THE MONTH FOR OWLS AND BATS!

An interesting evening weather-wise and detection-wise. We started the night under clouds and warmth had one NSWO and one Pallid Bat (Antrozous pallidus) capture on our first net check. And bats are so cool! The Pallid bat flies low to eat insects on the ground, which is why we frequently catch them in our nets, but only at the beginning of the season. Pallids use their big ears to detect prey and often turn their sonar off. That is why they sometime don't detect the net, but once they know the nets are there, they turn on the sonar to avoid capture.
A Pallid Bat, note large ears, eyes and teeth for capturing
ground-dwelling insects. Pallid bats often emit a musky odor
when disturbed, a good protection from predators- think skunk.
This is a web photo.
It was quiet and still after that, until the clouds parted, stars and cooler temps appeared and then came the owls.  Saw-whets, screech and great horned began to call and we banded three more owls near the end of our night. Weather likely made a difference. Thanks Sheila Frisk, Julie Newman, Wyatt Hersey and Steve King!

SECOND NIGHT OUT- 6 OWL SPECIES!

It most certainly was an owl night! We (Dawn, Steve, Ken and Wyatt) started out the evening with detections of Northern Pygmy Owl as we were setting up nets.  Then we heard a Barn Owl fly over the meadow, followed by Western Screech Owl, Northern Saw-whet and Great Horned Owl calling from the forest.  Biggest surprise.....wait for it..... scroll......
1st of fall 2015 NSWO, then 4 more!!
New to the team Wyatt Hersey with NSWO
and he also designed his cool t-shirt graphic
.... a Spotted Owl!  Yes, near the nets were heard the contact call of a Spotty: http://www.owlpages.com/sounds/Strix-occidentalis-2.mp3, very unusual but not the first record.  We discovered one (heard first giving the same vocalization) in 2012 while tracking radio-marked saw-whets on the Reserve. A great detection and a great night! Banded and released 5 NSWO and 1 WESO. Thanks banders!
