More Bluebirds

We have a second brood of baby Bluebirds in the nesting box (say that three times fast!) Neither the Tree or Barn Swallows did a second a round this year. I was really hoping the Barn Swallows would after the disaster, but they did not. There are four baby Bluebirds in the nesting box. Mom and Dad and the siblings from the first brood are all hanging around still. It's been great to have them and I was so pleased when Dave checked the box last week after noticing activity. I've noticed the House Wren has been very active lately and I'd like to get a look in their box to see if they are doing a second round. I wonder if the dry conditions are having an impact on the birds and their choices to do another round or not? We usually have two broods from the Tree Swallows. I'd also like to add that I have not seen a House Finch out here in months and months. I wonder if the eye disease wiped out the local population (that in the immediate vicinity). We definitely saw many birds suffering from it and it was awful. I see House Finches when I'm visiting my parents, but have not seen any here in probably a year. Also of note, almost all the fields where Bobolinks would nest were mowed by mid to late June and definitely all done by Canada Day weekend. Odds of any nesting success must have been slim to none in those areas. We did go out June 23rd and we heard many Bobolinks calling, but a week later the habitat was destroyed. I think, again, due to the dry summer, this lead to the hay being cut even earlier than usual. And in case I didn't mention it, we had s successful Baltimore Oriole nesting somewhere nearby. We had a male with two juveniles visiting the grape jelly feeder on a regular basis. Grosbeak numbers seemed to be down this year. We occasionally saw one female and two or three males, but that was it. There was one or two males who visited the grape jelly on a regular basis and that was it.
