AND NOW FOR THE BIRDS AND OTHER CRITTERS SEEN AT MEADOWLARK GARDENS

A juvenile Brown-headed Cowbird?  I looked at dozens of photographs and there are similar ones, but decided on this ID.  What do you think?  If you know for sure I am always open to learning.

The Red-winged Blackbird showed up as we were looking in the direction of the small bridge.

He was the only one we saw when we were at the garden. 

 I read at the above link the oldest recorded Red-winged Blackbird was 15 years, 9 months old.  It was banded in New Jersey in 1967, and found alive but injured in Michigan in 1983.  After recovering from its injuries it was released.

Two photos of a Grey Catbird.

It was a dreary day but it didn't stop its singing. 

A Baltimore Oriole or an American Redstart? I need help so to my more knowledgeable birders, please let me know if you can tell me for sure.  I would appreciate it and thank you in advance.
Added note 6-15-19: Thank you Ginny and Eileen for helping me with the identification of this bird.  On looking up lots of photos of Orchard Orioles, I believe this is what it is.  Among every other feature, the beak seemed to have a distinctive coloration.

We saw a few Chipmunks scurrying around.  

There were a lot of Red-eared Sliders.

The butterfly garden was very quiet and I couldn't see any butterflies.  

They did have a very nice poster and if you enlarge, you can just about make out the names of each one.

I enjoyed the ornamental butterflies...

and I saw this beauty on a lily earlier.  It is an Eastern Tiger Swallowtail.

I have one more post after this and I will be done with our walk around Meadowlark Gardens until the next time we go.

Thank you for looking and enjoy your day.
