As always very cool to see the friday postings!

Are the HHs and RT scheduled for a molt in the near future? I remember you mentioned previously that their exposure to light is manipulated but can't remember the details.

the harris hawks are well on their way -- they've each lost 5-6 primaries and their down now. they're on 15hours of daylight

the RT is about a month out, I'm thinking, and the first molt is usually late and incomplete. she's only up to 12 hours daylight now (don't increase more than 5% per week)

Lefty, I love the thread and the pics. Sorry to see the season come to an end. The birds are beautiful. Post some pics occasionally, thanks.

If I am understanding correctly, an adult redtail would need the equivalent of about 50 pheasants/year for survival?

maybe a titch more.

in the wild, they don't specialize in large game like pheasants / jackrabbits (high risk-high reward) , the prefer lower risk prey like rodents.

a big part of the training of a youngster in peak learning mode is turning them onto bigger game

Sir:

Curious how the red tails capture a pheasant. Do they flush the pheasant and grab it mid-flight or do they take the pheasant on the ground? Impressive feat either way. A pheasant is a big, strong fast bird.

Thanks,


Jordan

they're not fast enough to outrun a pheasant (or duck for that matter) in a straight away tail chase.

they are, however, more than strong enough to overpower one (they regularly take 6-7# jackrabbits = 3-4x their bodyweight).

they are trained to follow and wait on. if you can reflush the pheasant, they will get it virtually 100% of the time -- usually on takeoff or on second landing

Way cool again Lefty.

I'll assume (as a biologist, of slimy scaly things) that your comment earlier in the thread about "hormones" has to do with your girl RT looking for a boy somewhere? Or is it just the urge to migrate N from Utah?

I hope they have a nice spring/summer. You and the family too.

PS, my wife, our resident dog trainer/agility handler, was quite impressed with the capacity of the "grazer's" stomach revealed by the pic of the contents you posted the other day.

thanks Geno!

"hormonal" at this age means urge to migrate.

they don't reach sexual maturity until age four (if you thought puberty was rough with your kids, try to imagine them but with talons and 4x your grip strength!).

Gotcha,

No recent experience with hawks, but years ago my Africa Grey (timneh) could sink his hooks pretty good when he wanted! Maybe he was "hormonal" wink

Again, I sure appreciate the break from routine your birds provide.

PS. our 2.3 year old whippet doesn't seem to know how hard he's "playing" when he attempts to use his teeth. Of course, he sort of assumes I'm just another dog to play with. "Mom" is the boss.

Matt this past week my wife and I watched a demonstration at the Harrisburg outdoors show where the guy had both Redtails and Harris Hawks. I was surprised at the difference in size even though he said his redtail was unusually large (56+ ounces?). I'm just wondering what your birds hunting weights are?


They say everything happens for a reason.
For me that reason is usually because I've made some bad decisions that I need to pay for.

56oz (1500g) would indeed be a ginormous RT.

All three of my birds are females (1/3 larger than males) and all three fly at 980g (34oz), and molt at 1150g (40oz).

My Harris Hawks are on the large end of the scale - average is about 750- 800g for a female -and my RT is average for a western RT (eastern ones are more like 1200g flying weight)

RTs "look" larger both because they have shorter legs and tail making them look more compact. They also have twice the number of body feathers the HH have
