I went to check the M6 area one more time because it will closed for construction starting next Monday. I wanted to make sure there were no longer any chicks there or if any of the chicks would be in danger.
I noticed the male seemed to be protecting the area that was pointed out to me yesterday as the place where the nest originally was. So, I started there. I found the male and at least one other killdeer in that area. A third killdeer flew by and the second killdeer went off into the air and did evasive maneuvers while being chased by the third one. Both of those killdeer did not return, but Dad killdeer was still there.
I walked around the area and noticed he got very excited when I walked around some of the bushes. I thought that he might have already started a new nest, but saw none. Then, I sat down and waited. Soon, I hear the DEFINITE sound of a baby killdeer calling back, possibly two, though the other sounded much weaker. I went to the place where I thought I heard the sound and looked around, being careful where I stepped. I looked around this one big bush, but was afraid to step in any further because I knew one of the chicks like to dig under the leaves and was afraid of stepping on her. So, I went back and sat down.
I waited a while and listened to Dad call and for a long time, I didn't hear a response. I was worried that I had stepped on her. I moved further away and, finally, she started calling again. He continued to call and sometimes I would hear a response, sometimes I wouldn't. Dad was definitely responding to the call and sat down nearby, possibly offering a spot under his wing for his daughter(s). But, it was hot, so she (they) didn't come out of her (their) hiding places. Sometimes, the little chick will call back for several seconds.
Dad sat a little bit away and did very weak "broken wing acts", but not with a lot of enthusiasm. Then, he went back to the area where I heard the chick call. I left after that and it all got quiet.
I think that the little chick that likes to bury herself has survived and possibly her sister may have, too. I don't think there are three anymore, but I am sure there's one. I may name her Digger even though I really don't like that name too much, but it's the only one I can think of right now. I thought about naming her Firecracker, but that was the name I was going to give to the other chick across the lake.
