Dave:

Thanks for the reply. It may very well have been a tree frog - it was small
and didn't look menacing at all. I think I also read that bufo toads are not
terribly fast, and this little guy was gone in a flash.

I never have dog food outdoors - it would attract bugs and in this heat,
would probably go bad very quickly anyhow. There is a good amount of foliage
near the pond where a toad could find cover. However, there aren't many bugs
around - I spray the yard periodically to prevent fleas and ticks and that
also keeps the ants and other pests under control. No small critters either,
just the occasional squirrel.

I did find a new batch of eggs in the pond on Saturday, so someone is
definitely visiting. My yard is fenced in though, so unless a bufo can jump
or climb over a 6' fence I'm not sure how they would get in. There may be a
few small gaps here and there but there's no large openings for anything too
large to crawl under.

If I find eggs again, is there any easy way to tell if they are from a bufo
or a tree frog (which I assume are harmless). The little tadpoles I found a
week or two ago were chomping on the water lilies, if that's any indication
one way or another.

Thanks.
Don
