THIS GUIDANCE PROVIDES THAT THE TAX EFFECTS FROM AN UNCERTAIN TAX POSITION CAN ONLY BE RECOGNIZED IN THE CONSOLIDATED FINANCIAL STATEMENTS IF THE POSITION IS MORE LIKELY THAN NOT TO BE SUSTAINED IF THE POSITION WERE TO BE CHALLENGED BY A TAXING AUTHORITY. THE ASSESSMENT OF THE TAX POSITION IS BASED SOLELY ON THE TECHNICAL MERITS OF THE POSITION, WITHOUT REGARD TO THE LIKELIHOOD THAT THE TAX POSITION MAY BE CHALLENGED. AUDUBON HAS CALCULATED AN INCOME TAX PROVISION THAT IS IMMATERIAL FOR CONSOLIDATED FINANCIAL STATEMENT PURPOSES. AUDUBON HAS PROCESSES PRESENTLY IN PLACE TO ENSURE THE MAINTENANCE OF ITS TAX-EXEMPT STATUS; TO IDENTIFY AND REPORT UNRELATED INCOME; TO DETERMINE ITS FILING AND TAX OBLIGATIONS IN JURISDICTIONS FOR WHICH IT HAS NEXUS; AND TO IDENTIFY AND EVALUATE OTHER MATTERS THAT MAY BE CONSIDERED TAX POSITIONS.

FORM 990, PART III, LINE 1 - ORGANIZATION'S MISSION:	AUDUBON'S NEW STRATEGIC PLAN FOR FISCAL YEARS 2023-2028 ORIENTS AUDUBON TOWARD ACHIEVING A SINGULAR GUIDING STAR: HALTING, AND ULTIMATELY REVERSING, THE PRECIPITOUS DECLINE OF BIRDS ACROSS THE AMERICAS. AUDUBON WORKS ACROSS 11 COUNTRIES IN THE WESTERN HEMISPHERE, WITH 15 STATE AND REGIONAL U.S. OFFICES, 32 CONSERVATION ACTION CENTERS, AND 29 SANCTUARIES. THE ORGANIZATION SUPPORTS OVER 400 INDEPENDENT ACTIVE COMMUNITY CHAPTERS AND 100 CAMPUS CHAPTERS AND COLLABORATES WITH HUNDREDS OF PARTNERS ACROSS THE WESTERN HEMISPHERE. AUDUBON WORKS THROUGHOUT THE AMERICAS USING SCIENCE, PUBLIC ENGAGEMENT, EDUCATION, AND ON-THE-GROUND CONSERVATION. STATE, REGIONAL, AND COUNTRY PROGRAMS, CONSERVATION ACTION CENTERS AND SANCTUARIES, CHAPTERS, AND PARTNERS GIVE AUDUBON AN UNPARALLELED WINGSPAN THAT REACHES MILLIONS OF PEOPLE EACH YEAR TO INFORM, INSPIRE, AND UNITE COMMUNITIES IN CONSERVATION ACTION.
FORM 990, PART III, LINE 4A, DESCRIPTION OF PROGRAM SERVICE:	AUDUBON HAS NOW REACHED THE MIDPOINT OF FLIGHT PLAN, OUR BOLD AND TRANSFORMATIVE 2023-2028 STRATEGIC VISION TO FORGE A FUTURE WHERE BIRDS THRIVE ACROSS THE AMERICAS WHILE MAXIMIZING BENEFITS FOR PEOPLE AND THE PLANET. AUDUBON'S CONSERVATION PROGRAMS ADDRESS THE DUAL CHALLENGES OF CLIMATE CHANGE AND BIODIVERSITY LOSS BY DRIVING IMPACT IN FOUR KEY AREAS: CONSERVING PRIORITY HABITATS, ADVANCING CLIMATE SOLUTIONS, CHAMPIONING TRANSFORMATIONAL PUBLIC POLICY, AND GROWING AND BROADENING THE COMMUNITY OF BIRD ENTHUSIASTS ACROSS THE WESTERN HEMISPHERE WHO TAKE CONSERVATION ACTION. GUIDED BY SCIENCE AND STRENGTHENED BY PARTNERSHIPS, AUDUBON'S CONSERVATION EFFORTS ARE DEDICATED TO PROTECTING BIRDS AND THE PLACES THEY NEED, TODAY AND TOMORROW. AS A HEMISPHERIC ORGANIZATION, WE BRING OUR COLLECTIVE POWER TO "BEND THE BIRD CURVE" - HALTING AND ULTIMATELY REVERSING THE SHARP DECLINE OF BIRD POPULATIONS ACROSS THE AMERICAS. AUDUBON'S CONSERVATION EFFORTS ARE CARRIED OUT THROUGH ITS NORTH AMERICAN AND LATIN AMERICAN AND CARIBBEAN TEAMS, EACH LED BY MANAGING DIRECTORS. NORTH AMERICA ENCOMPASSES 15 STATE AND REGIONAL OFFICES IN THE U.S., THE CANADA PROGRAM, AND TEAMS DEDICATED TO HABITAT AND CLIMATE STRATEGIES FOR THE REGION. ADDITIONALLY, THE TEAM INCLUDES 32 CONSERVATION ACTION CENTERS AND 29 SANCTUARIES ACROSS THE U.S. AUDUBON'S LATIN AMERICA AND CARIBBEAN PROGRAM OVERSEES THE ORGANIZATION'S HABITAT AND CLIMATE INITIATIVES ACROSS CENTRAL AND SOUTH AMERICA AND THE CARIBBEAN. TEAMS FOCUSED ON COMMUNITY BUILDING AND POLICY, UNDER THE GUIDANCE OF MANAGING DIRECTORS, ARE DEVELOPING UNIFIED ORGANIZATIONAL STRATEGIES FOR OUR GOALS ACROSS THE WESTERN HEMISPHERE. THEY PARTNER CLOSELY WITH TEAMS IN NORTH AMERICA, LATIN AMERICA, AND THE CARIBBEAN. COMMUNITY BUILDING GUIDES THE ORGANIZATION'S APPROACH TO CONSERVATION ACTION CENTERS AND SANCTUARIES, OVERSEES OUR COLLABORATION WITH OVER 400 ACTIVE COMMUNITY CHAPTERS AND 100 CAMPUS CHAPTERS, AND DRIVES PROGRAMMATIC OPPORTUNITIES AND COMMUNITY SCIENCE INITIATIVES IN COMMUNITIES ACROSS THE AMERICAS. POLICY DEVELOPS STRATEGIES FOR POLICY PRIORITIES AT ALL LEVELS OF GOVERNMENT, LEVERAGING OUR SCIENCE AND POLICY EXPERTISE TO ADVANCE OUR OBJECTIVES. THE TEAM ALSO BUILDS AND ACTIVATES THE AUDUBON COMMUNITY TO DEMONSTRATE PUBLIC SUPPORT FOR THESE PRIORITIES. CONSERVATION FUNDING, EQUITABLE CONSERVATION, PARTNERSHIPS, AND SCIENCE ARE PROGRAMS THAT SPAN THE CONSERVATION TEAM, DRIVING IMPACT TOWARD THE CONSERVATION MILESTONES AND SUPPORTING THE NORTH AMERICAN AND LATIN AMERICAN AND CARIBBEAN TEAMS AND OUR COMMUNITY BUILDING AND POLICY PRIORITIES. AUDUBON IS ACHIEVING MEASURABLE PROGRESS TOWARD ITS CONSERVATION MILESTONES: HABITAT CONSERVATION: TO DATE UNDER FLIGHT PLAN, AUDUBON IS INFLUENCING MORE THAN 200 MILLION ACRES (80.9M HA) - AN EXTRAORDINARY ACHIEVEMENT THAT INCLUDES OVER 80.3 MILLION ACRES (32.5M HA) ALREADY CONSERVED AND ANOTHER 152.2 MILLION ACRES (61.5M HA) IN THE PIPELINE. THIS PROGRESS ADVANCES OUR AMBITIOUS GOAL OF CONSERVING 300 MILLION ACRES OF BIRD HABITAT BY 2028. KEY HIGHLIGHTS INCLUDE: A HISTORIC MILESTONE WAS ACHIEVED IN JULY WITH THE DECLARATION OF THE LOMA SANTA INDIGENOUS CONSERVATION AREA IN BOLIVIA, WHICH SPANS NEARLY 500,000 ACRES, SHELTERS 250 BIRD SPECIES, AND SAFEGUARDS THE CULTURAL HERITAGE OF FIVE INDIGENOUS GROUPS. IT IS THE LARGEST PROTECTED AREA ESTABLISHED TO DATE THROUGH CONSERVA AVES, A PARTNERSHIP LED BY AUDUBON, AMERICAN BIRD CONSERVANCY, BIRDLIFE INTERNATIONAL, BIRDS CANADA, AND THE LATIN AMERICAN AND CARIBBEAN NETWORK OF ENVIRONMENTAL FUNDS (REDLAC). CONSERVA AVES CONNECTED AND CONSERVED MORE THAN 660,000 ACRES IN 2025 ALONE. MARYLAND'S SALT MARSH LANDSCAPE IS DECLINING AT AN ALARMING RATE, WITH SIGNIFICANT IMPACTS TO FISH, SHELLFISH, BIRDS, AND LOCAL COMMUNITIES - A CRISIS WITH PARALLELS IN MANY COASTAL AREAS. TO COUNTER IT, AUDUBON COLLABORATED WITH LOCAL PARTNERS AND PUBLIC AGENCIES TO LAUNCH THE MARSHES FOR TOMORROW PROJECT. THE PROJECT HAS IDENTIFIED 29,000 PRIORITY ACRES OF SALTMARSH FOR PROTECTION AND RESTORATION AND SECURED A $13.2 MILLION GRANT FROM THE MARYLAND DEPARTMENT OF NATURAL RESOURCES TO ADVANCE PROJECTS THAT WILL SUPPORT THIS HABITAT. THESE EFFORTS WILL NOT ONLY HELP PROTECT VULNERABLE SPECIES LIKE THE SALTMARSH SPARROW, BUT ALSO STRENGTHEN THE ECONOMIES AND RESILIENCE OF COASTAL COMMUNITIES THAT RELY ON AGRICULTURE, TOURISM, AND FISHING. IN 2025, AUDUBON'S COASTAL PROGRAMS IN TEXAS PROTECTED 175 COASTAL ROOKERY ISLANDS ACROSS THE GULF COAST - CRITICAL HAVENS FOR MORE THAN 60,000 BREEDING PAIRS OF WATERBIRDS FROM 27 SPECIES. AUDUBON'S CONSERVATION EFFORTS ALONG THE GULF COAST DELIVER MEASURABLE BENEFITS FOR BIRDS AND LOCAL COMMUNITIES - SUPPORTING BIODIVERSITY AND PROTECTING NATURAL SYSTEMS THAT BUFFER STORMS AND STORE CARBON FOR A MORE RESILIENT TEXAS COAST. THROUGH ISLAND OWNERSHIP, LONG-TERM LEASES, COLLABORATIVE PARTNERSHIPS, AND PROACTIVE STEWARDSHIP, WE ARE MINIMIZING HUMAN DISTURBANCE AND HELPING ENSURE SAFE NESTING CONDITIONS IN THIS HEMISPHERICALLY SIGNIFICANT ECOSYSTEM THAT ANCHORS THE CENTRAL FLYWAY. AUDUBON PROTECTED NEARLY 200,000 ACRES IN FLORIDA THIS YEAR, INCLUDING MORE THAN 60,000 ACRES WITHIN THE GREATER EVERGLADES ECOSYSTEM. AS A CULMINATION OF AUDUBON'S RESEARCH ON LONG-TERM CHANGES AT CORKSCREW SWAMP SANCTUARY, THE SOUTH FLORIDA WATER MANAGEMENT DISTRICT LAUNCHED A THREE-YEAR RESTORATION PLANNING EFFORT. THE PUBLICLY FUNDED CORKSCREW WATERSHED INITIATIVE IS EXPECTED TO DIRECT MORE THAN $2 BILLION TOWARD RESTORATION PROJECTS ACROSS OVER 640,000 ACRES - WITH CORKSCREW SWAMP SANCTUARY AT ITS CORE. CLIMATE ACTION: TO DATE, AUDUBON HAS ADVANCED 70 PROJECTS THAT ACCELERATE DECARBONIZATION WHILE PROTECTING IMPORTANT HABITAT, MOVING FORWARD NEARLY 40 GIGAWATTS OF RENEWABLE GENERATION AND 10 GIGAWATTS OF TRANSMISSION. WE HAVE ALSO SEQUESTERED AND STORED 6.1 BILLION TONS OF CARBON, WITH AN ADDITIONAL 14.7 BILLION TONS PROJECTED FROM LANDSCAPES WHERE LASTING PROTECTION AND RESTORATION ARE ALREADY UNDERWAY - A POWERFUL REFLECTION OF THE IMPACT OF CONSERVATION ACTION TODAY. THIS MOMENTUM POSITIONS US TO HELP DEPLOY 100 GIGAWATTS OF RENEWABLE ENERGY BY 2028 AND TO ACHIEVE OUR AMBITIOUS GOAL OF STORING 30 BILLION TONS OF CARBON THROUGH NATURAL CLIMATE SOLUTIONS BY 2028. KEY HIGHLIGHTS INCLUDE: RICH IN BIODIVERSITY AND HIGHLY ADAPTABLE, MANGROVE HABITATS HAVE LONG BEEN ESSENTIAL TO COASTAL COMMUNITIES THROUGHOUT THE TROPICS. FINANCED BY THE UK BLUE CARBON FUND THROUGH THE INTER-AMERICAN DEVELOPMENT BANK, AND IMPLEMENTED BY AUDUBON AND THE PANAMA AUDUBON SOCIETY, THE BLUE NATURAL HERITAGE PROJECT ASSESSED THE CAPACITY OF MANGROVES IN PANAMA'S BAY OF PANAMA AND PARITA BAY TO SLOW CLIMATE CHANGE. FINDINGS SHOW THAT OVER THE NEXT CENTURY, THESE MANGROVES ARE PROJECTED TO STORE AND CAPTURE 26.6 MILLION TONS OF CO2 - GENERATING AN ESTIMATED $155 MILLION ANNUALLY IN ECONOMIC BENEFITS WHILE STABILIZING COASTLINES AND MITIGATING SEA-LEVEL RISE. THIS WORK MAKES A POWERFUL CASE FOR RESTORING AND SAFEGUARDING MANGROVE ECOSYSTEMS WORLDWIDE. AUDUBON TOOK CENTER STAGE AT CLIMATE WEEK NYC IN SEPTEMBER, BRINGING THOUGHT LEADERSHIP GROUNDED IN ROBUST SCIENCE. OUR EXPERTS PRESENTED A NEW FRAMEWORK FOR IDENTIFYING AREAS WHERE CONSERVATION CAN ADDRESS CLIMATE CHANGE WHILE BENEFITING BIRDS AND PEOPLE, AND HIGHLIGHTED AUDUBON CONSERVATION RANCHING AS A MODEL FOR NATURAL CLIMATE SOLUTIONS WITH SIGNIFICANT ECOLOGICAL AND ECONOMIC GAINS. A BILLBOARD FEATURING AN 80-FOOT-TALL HUMMINGBIRD IN NEARBY TIMES SQUARE CAUGHT THE ATTENTION OF TENS OF THOUSANDS OF PASSERSBY, SHINING A SPOTLIGHT ON THE CRITICAL ROLE BIRDS PLAY AS INDICATORS OF CLIMATE CHANGE. IN JANUARY 2025, AUDUBON RELEASED ITS BIRDS AND OFFSHORE WIND REPORT, OUTLINING A SCIENCE-BASED PATH TO ENVIRONMENTALLY RESPONSIBLE ENERGY DEVELOPMENT IN A CHANGING CLIMATE. THE REPORT EXAMINED THE UNIQUE ROLE AND ADVANTAGES OF OFFSHORE WIND RELATIVE TO OTHER ENERGY SOURCES AND IDENTIFIED STRATEGIES TO REDUCE POTENTIAL RISKS. IN CALIFORNIA, AUDUBON SUPPORTED THE ALLOCATION OF NEARLY $240 MILLION FROM THE STATE'S CLIMATE BOND FOR PORT UPGRADES AHEAD OF OFFSHORE WIND IMPLEMENTATION. THESE UPGRADES INCLUDE COMMITMENTS TO REDUCE PORT EMISSIONS AND WILL LAY THE GROUNDWORK FOR AN ADDITIONAL 4.5 GIGAWATTS OF OFFSHORE WIND ENERGY ON THE CALIFORNIA GRID.
FORM 990, PART III, LINE 4A	IN WISCONSIN, AUDUBON WORKED CLOSELY WITH A RENEWABLE ENERGY DEVELOPER TO ENSURE THAT PLANS FOR THE STATE'S LARGEST SOLAR ENERGY PROJECT - A 9,500-ACRE INSTALLATION CAPABLE OF PRODUCING 1.3 GIGAWATTS, ENOUGH TO POWER NEARLY 1 MILLION HOMES - PROCEEDED IN ALIGNMENT WITH STATE AND FEDERAL CONSERVATION GOALS. DORAL RENEWABLES AGREED TO IMPLEMENT AN APPROACH AT ITS PROPOSED VISTA SANDS SOLAR FARM THAT CREATES CONNECTED HABITAT FOR SPECIES LIKE THE GREATER PRAIRIE CHICKEN AND COMMITTED $2.1 MILLION TO SUPPORT WISCONSIN'S GREATER PRAIRIE CHICKEN RESTORATION PLAN. TOGETHER, THESE COMMITMENTS CLEARED THE PATH FOR PROJECT APPROVAL AND SET A GOLD STANDARD FOR COLLABORATIVELY ADVANCING CLIMATE SOLUTIONS. POLICY LEADERSHIP: BOLD POLICY ACTION AND SUSTAINED PUBLIC FUNDING ARE ESSENTIAL FOR REVERSING BIODIVERSITY LOSS AND ADDRESSING CLIMATE CHANGE. SINCE FLIGHT PLAN LAUNCHED, AUDUBON HAS CONTRIBUTED TO THE ADOPTION OF 100 POLICIES SHAPING A HEALTHIER FUTURE FOR BIRDS AND PEOPLE. KEY HIGHLIGHTS INCLUDE: AUDUBON MOBILIZED OUR MEMBERS TO SUPPORT THE BIRD BANDING LAB AND THE NORTH AMERICAN BREEDING BIRD SURVEY - PROGRAMS THAT HAVE QUIETLY POWERED CONSERVATION ACROSS THE UNITED STATES AND CANADA FOR DECADES BY PROVIDING CRITICAL DATA ON THE HEALTH OF THE NATURAL WORLD, INFORMING ENVIRONMENTAL DECISIONS, AND TRACKING PROGRESS TOWARD CONSERVATION GOALS. IN PARTNERSHIP WITH DUCKS UNLIMITED, THE AMERICAN BIRD CONSERVANCY, AND THE ASSOCIATION OF FISH & WILDLIFE AGENCIES, AUDUBON HOSTED A STATE OF THE BIRDS POLICY BRIEFING FOR 30 HOUSE AND SENATE STAFF FROM BOTH PARTIES TO HIGHLIGHT THE IMPORTANCE OF THESE PROGRAMS. NEARLY 24,000 COMMUNITY MEMBERS SENT MORE THAN 81,000 MESSAGES TO ELECTED OFFICIALS URGING THEM TO PROTECT FUNDING FOR THESE ESSENTIAL EFFORTS. SINCE 1988, MINNESOTA'S ENVIRONMENT AND NATURAL RESOURCES TRUST FUND HAS PROVIDED MORE THAN $1 BILLION FOR CONSERVATION EFFORTS, INCLUDING HABITAT PROTECTION, ENVIRONMENTAL RESEARCH, AND CLEAN WATER INITIATIVES. AUDUBON COLLABORATED WITH LEGISLATORS, TRIBAL COMMUNITIES, AND BLACK-LED, LATINO, AND HMONG ORGANIZATIONS TO MOBILIZE VOTERS AND BUILD SUPPORT FOR ITS RENEWAL. VOTERS OVERWHELMINGLY APPROVED THE FUND'S REAUTHORIZATION FOR ANOTHER 25 YEARS - THIS TIME INCLUDING A COMMUNITY GRANTS PROGRAM TO BENEFIT SMALLER ORGANIZATIONS. FINANCED BY THE MINNESOTA STATE LOTTERY, THE FUND IS PROJECTED TO GENERATE AN ADDITIONAL $2 BILLION BY 2050, SERVING AS A MODEL FOR HOW AUDUBON SCALES CONSERVATION IMPACT THROUGH PUBLIC FUNDING. TO HELP SECURE $16 BILLION FOR AGRICULTURAL CONSERVATION PROGRAMS, AUDUBON BROUGHT FARMERS AND RANCHERS FROM SEVEN STATES TO WASHINGTON, D.C., WHERE THEY MET WITH 38 CONGRESSIONAL OFFICES. IN A POWERFUL DISPLAY OF DIPLOMACY IN ACTION, THESE LANDOWNERS DELIVERED A CLEAR AND UNIFIED MESSAGE: CONSERVATION WORKS, AND THESE PROGRAMS MAKE IT POSSIBLE AND PROFITABLE TO CONTINUE THEIR RANCHING HERITAGE. IN JULY, KEY PROGRAMS SUPPORTING HABITAT, ACCESS, AND SOIL AND WATER QUALITY ON PRIVATE LANDS RECEIVED RENEWED FUNDING. WORKING IN PARTNERSHIP WITH CHILE'S MINISTRY OF THE ENVIRONMENT, AUDUBON HAS PLAYED A CENTRAL ROLE IN SHAPING AND IMPLEMENTING THE COUNTRY'S NATIONAL BIRD CONSERVATION STRATEGY. IN OCTOBER 2025, CHILE LAUNCHED ITS FIRST-EVER ACTION PLAN FOR THE CONSERVATION OF SEABIRDS, A NATIONWIDE EFFORT THAT COMPLEMENTS AUDUBON'S ONGOING HABITAT CONSERVATION WORK IN THE COUNTRY. DEVELOPED IN COLLABORATION WITH AUDUBON AND MORE THAN 20 NGOS, ACADEMIC INSTITUTIONS, AND CIVIL SOCIETY ORGANIZATIONS, THE PLAN WILL ADVANCE SUSTAINABLE PRACTICES, STRENGTHEN CONSERVATION ALLIANCES, AND EMPOWER COMMUNITIES TO PLAY AN ACTIVE ROLE IN PROTECTING SEABIRD HABITATS. COMMUNITY BUILDING: FLIGHT PLAN UNITES AUDUBON'S COMMUNITY WORK, LINKING CONSERVATION ACTION CENTERS, SANCTUARIES, COMMUNITY AND CAMPUS CHAPTERS, NEXT GENERATION PROGRAMS, COMMUNITY SCIENCE INITIATIVES, AND MILLIONS OF MEMBERS AND SUPPORTERS INTO A POWERFUL NETWORK OF ACTION. IN 2025 ALONE, AUDUBON DIRECTLY ENGAGED 2.3 MILLION BIRD LOVERS AND CONSERVATIONISTS THROUGH THIS NETWORK. KEY HIGHLIGHTS INCLUDE: AUDUBON SUPPORTS MORE THAN 65 MOTUS STATIONS THAT TRACK RADIO-TAGGED BIRDS ACROSS THEIR MIGRATIONS. THIS YEAR, AUDUBON STAFF INSTALLED A MOTUS TOWER AT CLAFLIN UNIVERSITY - THE OLDEST HISTORICALLY BLACK COLLEGE AND UNIVERSITY IN SOUTH CAROLINA AND HOME TO AN AUDUBON ON CAMPUS CHAPTER. IN AUGUST, THE CINAGA DE MALLORQUN ECOPARK IN BARRANQUILLA, COLOMBIA, INAUGURATED ITS FIRST EDUCATIONAL BIRD GALLERY, MADE POSSIBLE WITH SUPPORT FROM AUDUBON. THE SERIES OF 50 INFORMATIONAL PLAQUES HIGHLIGHTS THE ECOLOGICAL RICHNESS OF THE WETLAND, HOME TO MORE THAN 150 BIRD SPECIES, AND PROMOTES ENVIRONMENTAL EDUCATION AND CONSERVATION AMONG ITS MORE THAN 300,000 ANNUAL VISITORS. THE ECOPARK - A "SISTER CENTER" TO THE AUDUBON CENTER & SANCTUARY AT FRANCIS BEIDLER FOREST IN SOUTH CAROLINA - ALSO GENERATES ECONOMIC BENEFITS FOR COMMUNITY MEMBERS, WHO SERVE AS DOCENTS AND OPERATE LOCAL BUSINESSES. AUDUBON SUPPORTS BUDDING CONSERVATIONISTS THROUGH A CONSTELLATION OF PROGRAMS - FROM EARLY EDUCATION AT AUDUBON CENTERS TO CAMPUS CHAPTERS AND PROFESSIONAL FELLOWSHIPS WITHIN OUR ORGANIZATION. THESE PATHWAYS OFTEN LEAD TO REWARDING CAREERS IN CONSERVATION. FOR EXAMPLE, BRIAN CAMMARANO FIRST CONNECTED WITH AUDUBON THROUGH OUR CONSERVATION LEADERSHIP INITIATIVE IN FLORIDA, A UNIQUE CO-MENTORING PROGRAM LINKING COLLEGE STUDENTS WITH EXPERIENCED CHAPTER LEADERS. HE WENT ON TO LAUNCH A CAMPUS CHAPTER AT THE UNIVERSITY OF CENTRAL FLORIDA, JOIN PROJECT PUFFIN IN MAINE, AND RETURN TO FLORIDA AS A SENIOR COORDINATOR. TODAY, HE LEADS COASTAL STEWARDSHIP ACROSS THE PANHANDLE AND MENTORS THE NEXT GENERATION - JUST AS HE WAS ONCE MENTORED. FOR FOUR DAYS EACH FEBRUARY, MORE THAN 800,000 PEOPLE AROUND THE WORLD HEAD INTO WOODS, FIELDS, WETLANDS, AND BACKYARDS TO RECORD THE BIRDS THEY SEE AND HEAR FOR THE GREAT BACKYARD BIRD COUNT - A TALLY THAT REACHED 8,078 SPECIES THIS YEAR. SINCE ITS FOUNDING IN 1998, THE GREAT BACKYARD BIRD COUNT HAS HELPED AUDUBON, THE CORNELL LAB OF ORNITHOLOGY, AND BIRDS CANADA TRACK LONG-TERM CHANGES IN BIRD POPULATIONS BY CAPTURING A SNAPSHOT JUST BEFORE MIGRATION. IT HAS GROWN INTO THE WORLD'S LARGEST BIODIVERSITY-RELATED COMMUNITY SCIENCE EFFORT.
