What birdsavers does
Acopian BirdSavers is a privately-held, family-owned business founded in 1985 by Jeff Acopian in Easton, Pennsylvania, that manufactures and sells exterior paracord window screens designed to prevent bird-window collisions. The core product consists of 1/8-inch diameter dark olive green 550 paracord cords suspended vertically outside windows at approximately 4-inch spacing (with a 4.25-inch optimal), mounted via aluminum velcro tabs or screws/clamps. The spacing design is grounded in Dr. Daniel Klem Jr.'s peer-reviewed research establishing the "2-inch by 4-inch Rule" — that birds avoid flying through spaces 2 inches high or less and 4 inches wide or less — and is independently endorsed by the American Bird Conservancy (Threat Factor 5) and Cornell Lab of Ornithology. The company reports 12,218+ tracked installations across all 50 US states and over 30 countries, with case studies claiming 90-100% reduction in bird-window collisions at equipped sites.
The product line spans rectangular, trapezoidal, and arched window configurations, with Easy Deploy, bottom tie-down (for windy locations), and commercial AB-TB/AB-T variants for large-scale installations. The company sells primarily direct-to-consumer through its BigCommerce-powered birdsavers.com storefront with quote-based custom pricing, alongside $100 DIY paracord spools (1,000 feet) and free comprehensive DIY instructions that expand the addressable market to self-installing customers. Customer segments span residential homeowners (primary), commercial/institutional buildings (with LEED Pilot 55 - Bird Collision Deterrence qualification as a regulatory tailwind), conservation organizations, and educational institutions. Distribution is e-commerce-led with international shipping to 30+ countries; marketing is content- and community-driven via a 23-question FAQ, 140+ customer reviews, YouTube instructional videos, free downloadable flyers/posters, and an interactive installation map.
The business is founder-operated with no external funding, no disclosed headcount, no M&A activity, and no disclosed revenue. Strategic emphasis is on scientific validation, conservation community endorsements, and organic word-of-mouth growth rather than venture-scale expansion.

birdsavers partnerships and signals
Strategic signalPartnerships
Six partnerships are on record, tiered core and minor.
- Houston Arboretum & Nature CentercoreAfter experiencing hummingbird strikes on their newly installed UV Bird Safe Glass windows, Houston Arboretum ordered 30 custom BirdSavers (approximately 6' wide x 9.5' tall each) in March 2024. They documented bird strike data before and after installation, demonstrating effectiveness with zero hummingbird strikes on BirdSaver-equipped windows. This serves as a key case study for the conservation sector.
- Cornell Lab of OrnithologycoreCornell Lab installed 384 Acopian BirdSavers in 2022 on their Visitor Center and other buildings. The Cornell Lab specifically endorses BirdSavers on their All About Birds website, stating that 'Acopian BirdSavers, made of paracord, can be spaced 4 inches apart because of their greater visibility.' The installation demonstrates commercial-scale effectiveness with zero reported bird strikes after installation.
- Dr. Daniel Klem Jr. (Muhlenberg College)coreDr. Daniel Klem Jr. conducted peer-reviewed scientific field testing validating BirdSavers effectiveness. Research published in The Wilson Journal of Ornithology (June 2013). Klem is described as the world's foremost authority on bird-window collisions. His research proved the 2" x 4" Rule that validates BirdSavers' spacing design.
- American Bird Conservancy (ABC)coreAmerican Bird Conservancy tested BirdSavers and assigned a Threat Factor of 5 (lower = more effective, scale of 1-100). ABC specifically addressed misconceptions about the 2-inch spacing guideline, clarifying it applies to 2D markers on glass, not 3D BirdSavers. ABC's endorsement validates the product's effectiveness for consumers.
- Lafayette CollegeminorConnection through founder Jeff Acopian's family (engineers/naturalists with history at Lafayette College). BirdSavers installed at Hugel Science Center. Professor who was there for 16 years reported 'no more thuds' since installation. College magazine covered the Acopian family's bird-saving passion.
- Arenal Observatory Lodge & Spa (Costa Rica)minorCosta Rican nature lodge installed DIY Acopian BirdSavers in March 2017 after recognizing the bird collision problem at their facility. Documented significant decrease in collisions and reduced fatality rates when strikes still occur with BirdSavers installed. Serves as international conservation sector reference.

birdsavers competitors and assessment
Company assessmentDirect peers
- Feather Friendly: Feather Friendly is the closest direct competitor, manufacturing exterior bird collision deterrent markers (Teflon-coated dots and spacer strips with 5cm spacing rules). It uses a different methodology than BirdSavers' paracord cords but competes for the exact same customer: commercial LEED projects, residential bird-feeder owners, and conservation-driven buyers looking for exterior-mounted deterrents.
- WindowAlert: WindowAlert sells UV-reflective decals and static-cling markers that birds see but humans do not. The products are an alternative to BirdSavers' paracord and compete for the residential/hobbyist bird-feeder segment on ease of installation and dramatically lower price per window. WindowAlert's UV-based approach is the most common low-cost alternative consumers encounter when searching for bird collision solutions.
- BirdTape: BirdTape (and similar transparent tape-based marker products) sells exterior-applied vertical strips spaced per the 2\" x 4\" Rule. It is functionally a direct competitor to BirdSavers' paracord, with the key trade-off being aesthetic minimalism vs. BirdSavers' three-dimensional visibility. Active in the same residential and small-commercial channels.
- SOLYX Window Films: SOLYX produces architectural decorative and bird-deterrent window films applied directly to the glass surface (vs. exterior cord systems). As part of a broader architectural window film catalog, SOLYX targets the same commercial new-construction and renovation channel as BirdSavers' commercial variants (AB-T/AB-TB), competing on installed-versus-spec aesthetics and labor cost.
Emerging players
- Collidescape: Collidescape is an emerging visual-marker design solution that uses computer-vision-derived patterns to deter bird collisions. Although more research-oriented and not yet a mass-market hardware product, it represents the next-generation technical approach BirdSavers could face as building designers seek pattern-based specifications tied to peer-reviewed efficacy.
Others
- Walker Glass: Walker Glass (Canada) manufactures acid-etched and bird-safe patterned glass as a factory specification for new construction. As a building-material supplier rather than a retrofit product, it competes with BirdSavers by preempting the need for retrofit solutions when projects are built bird-safe from the outset — particularly relevant for LEED v5/new-build projects.
- American Bird Conservancy (ABC): ABC is the nonprofit conservation organization whose Threat Factor ratings (BirdSavers scored 5) and published materials validate BirdSavers and competing products. ABC does not sell products but functions as a gatekeeper authority whose product ratings drive consumer/institutional purchasing decisions across the entire bird-safe category.
- Cornell Lab of Ornithology: The Cornell Lab of Ornithology is BirdSavers' most high-profile institutional customer (384-unit 2022 installation) and a referral authority whose 'All About Birds' website endorses BirdSavers by name. Functioning as both customer and ecosystem validator, the Cornell endorsement materially shapes institutional buyer behavior across North America.
Broad incumbents
- Vitro Architectural Glass: Vitro Architectural Glass (formerly PPG Glass) is a major float-glass manufacturer offering bird-friendly patterned glass (e.g., AviProtek). It is a broad incumbent in the glass supply chain with a bird-safe SKUs; the strategic threat is that specifying Vitro at design stage eliminates the retrofit opportunity for BirdSavers.
- Guardian Glass: Guardian Glass is one of the world's largest architectural glass manufacturers, with bird-safe options such as patterned/UV-coated products. As with Vitro, Guardian's bird-safe glass offerings address the new-construction specification channel that could erode BirdSavers' retrofit growth runway over time.
