On June 1st, a few days after the western bluebird hatchlings were
preyed upon by a gopher snake, a pair of Violet-green Swallows, Tachycineta
thalassina, started to bring nest material into nest box #31. On the
night of June 10, the first egg was laid. Their nest is made of dried
grasses, pine needles and feathers which were added to the previous western
bluebird nest. On June 28, the 3 eggs hatched. Both parents enter the
nest box and feed the chicks. After watching the nest box for an entire
hour on June 30 at 2:00 pm, it is apparent that the female or male brings
food to the chicks about every 4 minutes on average. However, the female
is the only parent which sits and warms the chicks after they have eaten.

UPDATE (by Sheri): On July 13, 2000 a webcam viewer
sent us an email alerting us that something was in the nest box.
It turns out that it was a baby ground squirrel or chipmunk (most
likely a squirrel because they are more common and what I saw
on the webcam did not have stripes). I got to the box in time
to save the other two nestlings but the squirrel had eaten part
of the third nestling. I immediately put sheet metal around the
base of the tree. I hope the nestlings make it one more week
because by that time they will be strong enough and mature enough
to fledge the box. Thanks to the web viewer that alerted us to
the predator!

June 1, 2000: A pair of Violet-green swallows started
bringing in nest material and moving around the previous western
bluebird nest material in nest box #31.
June 10, 2000: Female laid her first egg sometime in
the middle of the night or early morning on the 11th.
June 11, 2000: Female laid second egg sometime in the
middle of the night or early morning on the 12th.
June 12, 2000: Female laid third egg sometime in the
middle of the night or early morning on the 13th.
June 13-28, 2000: Female incubates the eggs. Several
feathers have been added to the nest since the first egg was
laid.
June 28, 2000: 3 eggs hatched in the early morning.
The female and male remove the eggshells from the nest box. Since
that time, both the female and male are busy feeding the nestlings.
For detailed notes on the feeding behavior, click on the Detailed
Nest Box #31 Observations in the right hand column.
July 7, 2000: The nestlings are over a week
old. Their feathers are coming in thicker. The female is not
spending as much time in the nest box keeping the nestlings warm
(during the day). She and the male are constantly catching and
bringing them food; about every 2-3 minutes. There is an open
meadow close to the nest box so the parents don't have to travel
far for food.
July 13, 2000: Baby ground squirrel got into the nest
box and ate (partially) one of the nestlings.
