My boss used to get pigeons striking his third floor apartment window. I printed a life-sized, background trimmed off, color picture of a Cooper's Hawk eating a bird, and taped that to the window. No more pigeon strikes!   Michael Santner Westfield, MA   -----Original Message----- From: Angela Dimmitt Sent: Feb 13, 2022 9:07 AM To: bails@att.net , ctbirds@lists.ctbirding.org Subject: [CT Birds] Re: Window Strikes   The speaker at Litchfield Hills Audubon's Monday, March 7, monthly meeting is talking about this subject. "Making your windows safer for wild birds".  Vickie Dauphinais will be presenting in person, but the meeting will also be aired via Zoom.  Please check the website at lhasct.org - the calendar gives full details.  I will be sending the link to CTbirds nearer the time, and make sure you get it. Also, Vickie is curious to hear about others' experiences so I will forward your email to her. Take care, stay warm and safe - and I hope you have lots of careful birds at your feeders!Angela     -----Original Message----- From: Patricia Bailey To: ctbirds@lists.ctbirding.org Sent: Thu, Feb 10, 2022 7:48 pm Subject: [CT Birds] Window Strikes   I use a bright pink tape used at construction sites to alert people of obstacles.  The pink tape is not sticky.  I cut a piece and use tape attaching it to a large picture window.  It flutters in the breeze and works well.  Pat Bailey Sherman, CT      Message: 2 Date: Sat, 5 Feb 2022 17:20:03 -0500 From: George Wallace > Subject: [CT Birds] Re: Muntin bars and bird strikes To: ctbirds@lists.ctbirding.org Message-ID:     > Content-Type: text/plain; charset="UTF-8"   Hey Rob,   Muntin bars or mullions probably only prevent collisions some of the time. A bird approaching the window in just the right way may see the bar of the mullion as an obstacle and vere away from the window all together. Or it may dodge the mullion and go straight into the glass thinking that it can fly past it. In practice, decals and other stickers or visual obstacles need to be placed on windows so that they are no more than 2" apart. That seems like a lot of stuff on your windows but that is what it takes to prevent bird strikes on glass. Birds are used to flying between tree branches and other obstacles with incredible agility, so deterrents placed on glass need to be close together.   There is lots of information on this at https://abcbirds.org/glass-collisions/   Very best to all, George Wallace Salisbury, CT   CTBirds, a service of Connecticut Ornithological Association - Bringing birders together statewide.
