Bird watching is often a simple and fun activity for animal lovers and birders alike. Maybe you have birds right outside your door, or maybe this is an opportunity to take a drive to an area where wildlife can be seen. See where the conversation leads as you talk about what you notice. Are there birds in the water? How many different bird calls can you hear? Can you recognize the types of birds you see? This will stimulate the mind and can even be a spiritual experience as you and your loved one connect with nature.
Seasonally you may notice migratory birds in the area and this can organically lead to conversations about migration and your observations. An activity such as watching a well-known nature film such as Fly Away Home or Winged Migration can further evoke mentally stimulating dialogue.
There are many books on bird calls and bird identification that can lead to future activities of interest and inspiration!
