This is the second installment of the webinar series on Reuniting and Renesting Orphaned Wildlife. The first webinar talks about urban wildlife conflicts, reuniting steps and framework, and specific guidance when reuniting mammals such as squirrels and deer. Meanwhile, this session focuses on efforts, considerations, and other tips for reuniting birds.

John Griffin is back on the Justice Clearinghouse to continue his discussion. John has more than 20 years of field experience resolving conflict issues with wildlife from raccoons to great apes. He is currently the Senior Director of Urban Wildlife Programs for the Humane Society of the United States.

Specifics of this course include:

  • Emphasizing the reason and importance of reuniting juvenile wildlife with their parents in terms of the animals’ survival and the saved time, effort and costs for those who respond to these calls.
  • Looking back at the past session highlighting the value of vocal luring and how maternal behavior plays an important part in facilitating reunifications.
  • Outlining the decision framework for renesting and reuniting efforts for birds.
    • Elements to look into when building a complete case history.
    • Factors to take into account before trying to help and when deciding to reunite a juvenile bird with its parents.
    • Critical precautionary measures to bear in mind and protective equipment to have when attempting to handle, transport, or renest a bird.
  • Common reasons that may cause the separation of the juvenile from the parent that must also be considered when reuniting or renesting them.
  • Some of the most common reasons for the calls for service involving juvenile birds, guidance for these, and the different responses to implement based on the age of the juvenile bird.
  • Guidelines and other things to consider when making and using substitute nests.
  • The importance of monitoring after renesting to ensure that it results in successful reunification.
  • Typical issues faced with cavity-nesting birds, its causes, and how to appropriately address these.
  • Common concerns that endanger ducks and geese and their young and ways to resolve this and put them back to safety.
  • Special considerations, knowledge, and skills required when dealing with raptors, and how to determine a juvenile’s age based on its behavior.
  • Guidelines when renesting or reuniting juvenile raptors with parents and employing methods like recorded calls and hacking to assist with this.
  • Case examples were provided to demonstrate how other agencies handled renestings and reunifications within their jurisdiction.
  • The value in building a potential reuniting team made of volunteers and paid staff that can be mobilized for such situations.

Questions from the webinar attendees were about:

  • Raising awareness and getting involvement from other stakeholders like electric companies to prevent conflicts with wildlife triggered by their activities.
  • Details of the time-release food delivery system used for a hacking case example.
  • Whether parents transfer their juveniles in a substitute nest back to the original nest.
  • Resources for shareable graphics that can be used in awareness and education efforts and bird calls that can be used in calls for services.
