Hatching Update

Wow, did it get busy fast. I have a breather for the morning, so I wanted to quick catch up. Here’s what we have:

  • Chicago, Broadway: Five eggs were laid in early April. This means we should have chicks hatching around May 13-15.
  • Chicago, Millennium Park: Four eggs were laid in early April. On 09-May, Mary and Matt checked the nest and there were three chicks, about 1-2 days old.
  • Chicago, Pilsen: Four eggs were laid in early April. On 05-May, the nest was checked and there were at least two chicks, about 1-2 days old.
  • Chicago, River Birds: Five eggs were laid in early April. On 05-May, the nest was checked and there were at least three chicks, about 1-2 days old.
  • Chicago, South Loop: Four eggs were laid in early April. On 05-May, two chicks hatched. Since then, two eggs have remained, and probably will remain, unhatched. This is not uncommon and is no cause for alarm.
  • Chicago, St. Mary’s Hospital: Five eggs were laid in early April. By 10-May, two of the eggs had hatched.
  • Chicago, UIC: Three eggs were laid by the new UIC pair starting 01-May. This means chicks won’t begin hatching until early June, which is when we’ll be banding at most of the other sites. Due the the nest turnover, the new UIC pair got a late start.
  • Chicago, Wacker: One egg was laid on 08-Apr. I will be going there this week to see what is going on.
  • Chicago, Wrigleyville: This is a new nest. Matt and I will be going there later this week to get an update. Four eggs were laid in early April.
  • Evanston: Four eggs were laid in early April. The chicks started hatching on 06-May. All four are hatched now.
  • Savanna: Five eggs were laid in early April. Unfortunately, the nest cam has been very flakey, but we believe at least one chick has hatched by now from the brief glimpse we got from the camera last week.
  • Waukegan: Three eggs were laid in early April. One chick was visible on camera by 06-May. More may have hatched by now.

We have another 10 or so sites that are on the observation list, so will have to see about those!
