The migratory birds of New York connect the state to locations throughout the United States and the Western Hemisphere. Conservation of New York's migratory birds across the full annual cycle requires consideration of stationary non-breeding and migratory stopover habitat in addition to their breeding ground habitat. Below, we provide:

(1)  A state-level overview of where the migratory birds that breed in New York are found during the non-breeding season based on Shared Stewardship Connection Maps.

(2)  An overview of New York's Focal Migratory Species. This includes:

1.    Conservation status
2.    Multi-species connection map that shows connections for focal species based on tagging data of individual birds

(3)  Focal Species Accounts that provide detailed information on New York's focal species. This includes:

1.    Conservation statistics and information about current Southern Wings projects
2.    Species Connection Maps that show connections across the annual cycle for each species based on tagging data of individual birds
3.    Conservation challenges
4.    Links to additional resources

(4)  Partner organizations working in countries connected to New York.

(5)  Additional resources
 

Shared Stewardship Connections

These maps show where 57 migratory species that breed in New York are concentrated during the nonbreeding season using year-round distribution models from eBird Status and Trends. They highlight opportunities for conservation across the full annual cycle of birds by informing locations for joint stewardship actions. Shared stewardship, on the left, represents the strength of connection between New York and the nonbreeding distributions of New York's migratory birds. Shared stewardship uniqueness, on the right, shows this information relative to all 50 states, emphasizing the hotspots where New York has unique connections compared to other states. The values in each 3 x 3 km pixel combine information on the number of species, the nonbreeding abundances of those species, and the percent of each species’ breeding population in New York.

We have compiled a list of 25 Neotropical migratory species that breed in New York and have been identified as focal migratory species across multiple groups and initiatives. For more information about how this list was created,  please see the section below "How was this table created?" By broadening the scope of this list beyond the Species of Greatest Conservation Need (SGCN), our intention was to create a resource that accounts for changes in SGCN associated with updated State Wildlife Action Plans (SWAPs) and provides a resource that has applications beyond updating SWAPs. We anticipate this list to update over time as SGCNs and other groups and initiatives revise their species lists.

For each species, we include the following information in the table:

• SGCN: Whether it is listed in New York's 2015 Wildlife Action Plan (yes or no).

• BCC: Whether and where it is a Regional SGCN (region or blank).

• R2R: Whether it is a Road to Recovery Tipping Point Species and on which Alert List (Red, Orange or Yellow).

• % breeding pop:  The estimated percent of the species’ global population breeding in New York (source: eBird state-level data). Data are only shown for modeled species.

• Focal Account: Do we provide a focal species account (yes or no).

How was this table created?

We determined the list of focal migratory species for the state based on whether they satisfied any of the following criteria, specifically species were listed as:

• SGCN in the 2015 Wildlife Action Plan (source: USGS database), with more recent updates provided by some states;
• Regional SGCN (RSGCN; source: AFWA regional associations, MAFWA, NEAFWA, SEAFWA; we were not aware of any RSGCN list for WAFWA);
• Road to Recovery Tipping Point Species (R2R) that breed in the state;
• Neotropical migrants (source: USFWS Neotropical Migratory Bird Conservation Act species list and Partners in Flight Avian Conservation Assessment Database). We included partial migrants for states bordering Mexico or the Caribbean islands (CA, AZ, NM, TX, FL), or where requested by the state.

The complete table for download includes the following information for each species:

• SWAP: Whether it is listed in the state’s Wildlife Action Plan (yes or no),
• RSGCN: Whether and where it is a Regional SGCN (region or NA)
• BCC_status: Whether and where it is a USFWS 2021 Bird of Conservation Concern (region or NA)
• R2R_level: Whether it is a Road to Recovery Tipping Point Species and on which Alert List (Red, Orange or Yellow)
• pct_ brding_pop: The estimated percent of the species’ global population breeding in the state (source: eBird state-level data. Data are only shown for modeled species. 
• Nb_biome: Non-breeding biome (source ACAD)
• Nb_hab_1: Broad non-breeding habitat class (source ACAD)
• Nb_hab_1: Descriptive non-breeding habitat class(source ACAD)
• Focal: Do we provide a focal species account (TRUE or FALSE)

For a selection of focal migratory species relevant to New York, we provide an account with detailed information about their conservation status, a Species-specific Connections Map illustrating its hemispheric connections across the annual cycle, and a list of  the conservation challenges (human activities and environmental changes) faced across the year, current Southern Wings projects and links to additional resources about each species. 

Species accounts were selected in consultation with state agency staff based on the Focal Migratory Species List. In brief, species were selected from the Focal Migratory Species List by extracting all SGCN based on 2015 SWAPs and prioritizing species based on: (1) the percentage of the breeding populations in New York; (2) each species’ Road to Recovery level; and (3) input from state agency staff. We expect the list of species accounts to change over time as state’s release updated SWAPs and SGCN. 
 

Species Connections Map
The species connection maps show direct connections between New York and locations across the Western Hemisphere based on tagging data in the Bird Migration Explorer available for each of the state’s migratory species of concern. Connections are based on bird band encounter records, automated radio telemetry, archival geolocators, satellite and GPS tracking, or genetic markers that document the movement of individual birds. The maps display locations (i.e., hexagons) that are connected to New York (polygon outlined orange) and illustrate the need to protect, restore, enhance and manage safe habitat in those areas to ensure species can satisfy their biological requirements across the full annual cycle. As individual birds travel between the species’ summer (breeding) and winter (stationary non-breeding) ranges, they traverse geopolitical boundaries, underscoring the need for collaborative and coordinated conservation efforts to maximize the return on conservation investments for the species in New York. While these maps offer valuable insight, they do not capture the complete picture of all connections, because they only present tagging data available in the Bird Migration Explorer. In some cases, species may not have a connection map, because no tagging data are available.

How were the species connections maps created?

The species connections maps are based on millions of observations generously shared by a variety of data holders and partner organizations. Key sources of data for tagged birds include: band encounter records from the USGS Bird Banding Lab, automated radio telemetry from the Motus global wildlife tracking network developed and managed by Birds Canada, location data from hundreds of tracked birds shared by our partners and the research community on Movebank, and genetic connectivity data shared by the Bird Genoscape Project. Seasonal ranges are derived from eBird at the Cornell Lab and data from BirdLife International and Audubon. The original data are archived by each of these partners. The tagging data are summarized across all datasets (including years 1914-2023) for the species.

Bird movements were aggregated and summarized into 150-km hexagons covering the Americas. We pre-processed data to remove points with high locational error (i.e., outliers), such as points collected during the equinox period for light-level geolocator data and incomplete or questionable banding and automated radio telemetry records.

For each species, the remaining points were intersected with a 150-km hexagon grid. We considered hexagons to be connected so long as the same individual occurred in both of them, whether those occurrences were within the same year or across multiple years. We filtered the linked hexagon pairs to just those with hexagons intersecting the state.

The final species connections maps display the hexagons that are connected to the state (dark purple) as well as hexagons with available tagging data for the species (light purple) with no direct connections to the state.

Conservation Challenges

Conservation Challenges are human activities and environmental changes that a species is sensitive to during its annual cycle. Threats are defined as human activities and environmental changes that negatively impact a migratory bird species (Salafsky et al. 2008); however, many human activities that present threats to birds can also present a component of the solution. The term “conservation challenge” conveys both the risk and opportunity associated with each of these activities. 

The list of conservation challenges provided for each species is derived from the conservation challenges that are included in the Bird Migration Explorer, which are those conservation challenges that are accurately and consistently mapped across the Western Hemisphere.

How were conservation challenges identified?

We used the list of 19 conservation challenges that were included in the Bird Migration Explorer. The “About the Bird Migration Explorer Conservation Challenges” provides a detailed description of how the 19 challenges were selected for inclusion in the Explorer.

The Bird Migration Explorer used the conservation lexicon developed by Salafsky et al. (2008) and subsequently used in multiple conservation planning frameworks to identify the conservation challenges relevant for each migratory species. In this framework, threats are defined as human activities that negatively impact bird species (Salafsky et al. 2008). Sensitivity is the extent to which stresses linked to threat exposure negatively impact a species. Based on a combination of literature review and expert knowledge within this framework, 88 threats relevant to migratory birds were developed. Stresses are the attributes of a species’ ecology that are impaired by threats (Salafsky et al. 2008). The Explorer used a list of seven stresses adapted from the list used by IUCN (International Union for Conservation of Nature 2012). Next, to identify a subset of threats that each species was sensitive to, a literature review was conducted to determine which threats have a negative impact on a species and the stresses that the threat causes to it. In cases where there was no information on a species sensitivity to a threat, but sensitivity to the threat was documented for a similar related species (e.g., same genus, or similar life history characteristics), both species were considered to be sensitive to it.

Next, threats were pooled into conservation challenges (e.g., agricultural pesticide/herbicide application and agricultural development threats were merged into the conservation challenge of agriculture). The list of conservation challenges was narrowed to those that could be accurately and consistently mapped across the Western Hemisphere, which resulted in 19 conservation challenges that were included in the Bird Migration Explorer. Because some conservation challenges, like invasive and problematic species (e.g., outdoor cats) do not have available hemispheric maps, the list of conservation challenges is not comprehensive. The list of conservation challenges on the Bird Migration Explorer and included in this online guide include:

• Urban Areas
• Surburban Areas
• Coastal Modification
• Agriculture
• Livestock Management
• Oil and Gas Production
• Wind Turbines
• Roads
• Power Lines
• Communication Towers
• Forest Management
• Coastal Disturbance
• Groundwater Depletion
• Surface Water Management
• Light Pollution
• Water Quality
• Sea Level Rise
• Increasingly Severe Flooding
• Drought
