I've been watching this little bird for a few days now. He manages to fly in and sit on the deck, alone. When the others fly off, he remains, regardless of the threat the other birds have detected. Each day I've ventured near but he struggles to fly off.
This morning, he barely made an effort to get away. So I scooped him up and brought him inside. I know there is nothing I can do. I know that when I peek on him at some point, probably today, he will have died. I feel so helpless. But I couldn't leave him to be ravaged by a stray cat. So I must take comfort in the fact that what I can do is give him a soft and safe place for however long he remains.
