Re: JOHN BARROW: Winch questions

Good morning colliemom/Alice, I have not had any problems with my Fulton winch seizing up. I do periodically spray the moving parts and cable with a spray lubricant recommended to me called Fluid Film available on Amazon for about $10 a can. Spray the axle of the winch and the sides of the cable spo...

Re: Low temps that they can surivive

Purple martins can survive extremely low temperatures. In the Texas freeze we had 5 days of continuous sub-freezing-non feeding- temperatures as low as 15 degrees. Martins can survive those temps. What they can't survive is loss of food and degradation of their body mass. We were supplemental feedin...

Re: Why I don’t have Martins back?

Tommy Coley, First of all I will report that we had an arrival yesterday evening of 50-100 new migrants in advance of the dry frontal system that has brought cooler weather today. As near as I could tell all of these arrivals were ASY, probably the first massive arrival of the 2 yoa class, mixed wit...

Re: ASY Female question

Cavity domination! She, and probably her mate(s) are trying to claim multiple cavities. One of those will end up with a subadult pair raising their offspring.

If you cannot find the link use the search link for "Halftime in Texas". It was first posted on April 10 ...

Re: Troyer Gourd inspection cap fail

Dean, If you're only having this continuing problem with a single gourd, try running a layer of electrical tape around the perimeter of the gourd threads. That should tighten the hold for the cap. I was cleaning some gourds that my wife offers at a public site last week and encountered one gourd alt...

Tdart, There is probably not a lot to be gained this late in the season.. For you, nest season is your first opportunity.

Hanover Bill, A couple of thoughts having visited the Erie roost two times.

It attracts martin...

Re: From Colony to Roost, What do they do ??

THOUGHTS ABOUT ROOSTS & FALL MIGRATION==TX

Reading through recent posts there seems to be some confusion about the dynamics and timing of migratory roosts and migration timing of purple martins nesting in TX. During the nesting season adult martins, particularly ASY males will establish a local roost in the area, often over-nighting at the l...

Re: Cresent Versus Modified Excluder Entrances?

Dan, All three entrances are starling restrictive. The excluder entrances are the most restrictive due to the built in "pips" that restrict a starling from turning sideways to defeat the entrance. The excluder entrance offered with excluder gourds is the excluder 2. It is the latest design and is th...
