Barn Swallow and I dunno what from PA

These birds live in my father's barn, they are so incredibly fast that I cannot compare them to anything I have ever seen before. They eat bugs out of the air over the pond, and they are playful, and impossible to photograph at all before I got a d2h, shots are with 70-200VR and some also with 1.4TC

Looking at my pictures, I think we have two different birds here, the one in the fourth picture is so different, but I dunno. In the air they look like a blur of color that shines blue in the sun on their back. They cartwheel around and change direction like acrobats










ok this other bird my dad says is a gold finch, but it was bigger than any finch I have ever seen, it was almost as big as a robin. This picture is cropped so it looks poor, but if anyone can identify this bird for sure I would love to know.

 

Dave,
I think you are right, thanks so much for your identification!

 

Yes, however for birding I think a D2x is really almost mandatory unless you have super big glass or fantastic technique, as you have to crop like mad and the extra resolution is a plus.

 

Bob,
Thanks on that UFO, I thought it was an Oriole myself, but I was told that they are orange- I know usually, but...
"Orchard Oriole" I will have to look that up.

PhotoDawg, thanks, they were super tough, though they like to sorta swoop around you while you are taking photos (providing plenty of photo ops). My dad says they are eating bugs you strike up by breathing/walking, but I suspect they are just playing with you.
When I didn;t bring out my camera, I swore they would fly around me so s-l-o-w-l-y, as if they were messing with me cause they knew.

 

One last one
