SUPPLEMENTARY INFORMATION:
Background
The black-capped vireo is an insectivorous songbird that breeds in Oklahoma, Texas, and northern Mexico, and winters along the western coastal states of Mexico. The vireo was listed as endangered under the Endangered Species Act of 1973, as amended (Act; 16 U.S.C. 1531 et seq.), in 1987, due primarily to nest parasitism by brown-headed cowbirds (Molothrus ater) and loss of habitat from urbanization, grazing, removal of vegetation for range improvement, and succession (52 FR 37420, October 6, 1987).
On December 15, 2016, we published a proposed rule to remove the black-capped vireo from the Federal List of Endangered and Threatened Wildlife (List) (81 FR 90762). Our proposed rule was based largely on the Species Status Assessment (SSA) Report, which characterized the overall species' viability in the future. In the SSA Report, the impact of brown-headed cowbird parasitism on certain locations was expressed in terms of sustainability and expansion of populations. Additionally, the black-capped vireo was identified as ``conservation-reliant'' due to successful recovery actions being implemented, largely cowbird management. In this document, we provide clarification to the information regarding cowbird management.
The Service believes cowbird management was a major factor leading to the recovery of the species, and the importance of cowbird management was discussed in the SSA Report. Particularly, the black-
capped vireo population in Oklahoma and localities in the eastern portion of the Texas range may be reliant on cowbird management periodically, or perpetually, to ensure minimal losses of current population numbers. In this regard, we assume the species may be ``conservation reliant,'' due to efforts necessary to retain healthy shrublands and reduce brown-headed cowbird parasitism under certain conditions in portions of the range. Based on the comprehensive information collected for the SSA Report, there is inherent uncertainty in forecasting future threats and population status scenarios over a 50-year timeframe. To address this uncertainty and ensure that the black-capped vireo continues to prosper, the SSA Report noted the importance of continued management of known populations of the species. To further this recommendation, the Service has obtained mutual commitments with many of our partners in the form of cooperative management agreements or other strategies to continue to manage known populations of the black-capped vireo and implement the PDM plan. These cooperative management agreements are included in the PDM plan, and provide assurances that PDM will detect trends in the black-capped vireo status and threats and the species' biological status will continue to improve.
In addition, we have corrected errors in Table 14 of the SSA Report (page 105). This table presented the results of forecast scenarios under short- and long-term managed and unmanaged conditions from Table 13, which is correct. Among the corrections to Table 14 was the shifting of one ``likely resilient locality'' in the short-term worst-
case scenario between recovery units, and identifying one less ``manageable locality'' in the long-term worst-case scenario. These corrections do not change the results of the SSA analysis. The SSA with the corrected table is included in the docket (FWS-R2-ES-2016-0110) for the proposed rule on www.regulations.gov and can also be accessed at https://www.fws.gov/southwest/es/ArlingtonTexas/.
For more background information on the black-capped vireo, refer to our Black-capped Vireo Species Status Assessment (SSA) Report available in the docket (FWS-R2-ES-2016-0110) for the proposed rule on www.regulations.gov and also at https://www.fws.gov/southwest/es/ArlingtonTexas/.
The Act, section 4(g)(1), requires us to implement a system, in cooperation with the States, to effectively monitor the status of each species we remove from the Federal Lists of Endangered and Threatened Wildlife and Plants due to recovery. The monitoring must occur for at least 5 years. The PDM's purpose is to verify that a species we delist due to recovery remains secure from risk of extinction after we remove the Act's protections.
To fulfill the PDM requirement, we drafted a black-capped vireo monitoring plan in cooperation with the Texas Parks and Wildlife Department, Oklahoma Department of Wildlife Conservation, Fort Hood and Fort Sill Military Installations, and The Nature Conservancy of Texas. Over a 12-year period, we propose to monitor abundance trends at managed localities with known populations of greater than 30 adult male vireos, estimate population trends at 4 major localities, and monitor the residual threats of brown-headed cowbird parasitism, land
Page 11164
use changes, and densities of livestock and deer.
Abundance monitoring would focus on known black-capped vireo localities under some form of management and for which the SSA Report forecasted future persistence. Through monitoring these localities, we can track abundance trends and compare those to the SSA Report forecasts. Additionally, four major localities with several years of population trend data will continue to be monitored to detect changes in trends over the 12-year period. In conjunction with abundance monitoring, a subset of vireo nests will be monitored to determine brown-headed cowbird parasitism rates at these localities. The PDM plan defines monitoring thresholds which, if reached, may result in additional actions. The monitoring thresholds are based on maintaining resiliency, redundancy, and representation, as described in the black-
capped vireo SSA Report. Land use trends, livestock, and deer within the vireo's range will also be monitored to ensure we detect changes that may affect the species.
The draft PDM plan includes both interim and final reporting requirements. If PDM results in a concern regarding the vireo's status or increasing threats, possible responses may include an extended or intensified monitoring effort, additional research, or an increased effort to improve habitat and reduce the threat. If future information collected from the PDM, or any other reliable source, indicates an increased likelihood that the species may become in danger of extinction, we will initiate a black-capped vireo status review and determine if re-listing the species is warranted.
In addition to public review of the draft PDM plan, we are requesting independent expert peer review from knowledgeable individuals with scientific expertise that includes knowledge of song bird ecology and conservation biology principles. Draft PDM plan peer review is in accordance with our policy ``Notice of Interagency Cooperative Policy for Peer Review in Endangered Species Act Activities,'' published on July 1, 1994 (59 FR 34270).
