More Purple Martins

Purple Martins
Last year, I was involved with a project to use color bands on Purple Martins to help learn, among other things, about some of their migration habits. The bands are easier to read than the standard USFWS silver bands, though those are still applied as well. Here are a few pictures from a recent banding session. The egg pictured here did not hatch and was removed from the nest box/tray. See how small they are? The next photo shows Mark Newstrom banding one of the chicks. It is a very delicate process (I know - I got to do 30 or so of them this year!) - you have to be careful of their fragile feathers, and their legs.Monday, July 12, 2010
Songbird youngsters

A few weeks ago at Springbrook Nature Center banding session, we definitely got a great surprise - a Yellow-throated Vireo! We could hear them (multiple) singing in the treetops, so we knew they were around. The best part? A female with a definite brood patch, which was definitive proof that they were breeders there!Wednesday, July 7, 2010
Baby Season

It's baby season! All over the metro, species of just about every kind have been able to adapt to urban situations. Take these Coopers Hawks and Red tailed Hawks - the Coops are in front of a hall on the University of Minnesota East Bank campus. Hundreds
of students walk right under their tree every day. The two chicks look like they were just fed. Mom watched me from a nearby scaffolding on a building just next door. The Red tails were hatched in a tree in south Minneapolis. Both actually have mailing addresses! The Red tails were learning how to hunt - or at least one of the three sibings was learning. One was watching from a nearby deck railing, and one was learning that on top of a nearby roof was not the best place to stay hidden from Blue Jays or Crows.

Peregrine Siblings
Here is a little story (in pictures) of the Lock and Dam #1 Peregrines. Got to watch one of them take the very first flight (okay, 20 foot hop) from the nestbox. Also got to see Mom bring in a kill but not actually give it to the youngsters in the box - she did three fly-bys to encourage them to come out and get it. This would, in essence, encourage them to try flying and leave the nest box. What you see here is a series of two of the chicks - almost six weeks old, so just about the right age to fledge. First you have to divide up the room on the perch to flap your wings. I think someone is on someone else's side.
Uh-uh - two babies on ONE side is probably not going to work.
