Watching: News From Observation Posts
time we reported the
migration in full swing, but wait till you see this week's
numbers! No additional cow/calf pairs appeared in the past two
weeks, but exciting pulses continue past our California point-count
and #7 on the clickable globe), with a record-breaking 41 whales
in one day at Gray Whales Count. At
Post #8, Wayne Perryman reports: We had 85 adults and 1 juvenile
recorded on March 24, Day 1 of the 2008 Cow/Calf Census. No calves,
but this is early for that phase of the migration. He summed up:
Pretty normal here in paradise.
up the coast, observers in Oregon (#11) and Vancouver
are beginning their northbound
gray whale season. We
also have reports and photos from the birthing
grounds (#2) in Mexico — where the whales play, rest, and
investigate their curious visitors before heading north to their
waters. How many babies will soon head north? Stay tuned!

and Vanessa are two happy girls! With their parents and grandparents
they visited the whales in the lagoons. Their mom said, "Our
first day was gorgeous with no wind, sunny skies, and glassy water.
On Feb. 5 the census was about
and we probably saw 100 whales that day.
They were everywhere — spyhopping, breaching, spouting. We saw
about a dozen cow and calf pairs.
second day the sea was choppy, but within a few minutes our boat and
another were visited by two juvenile males. We were all
able to pet them, be sprayed by them, and watch them toy with us!
One stayed longer, rubbing on the pangas. Once he floated on his
back between the boats, waving his fins like he was performing at
Sea World." Fun!

is Counting Whales So Tricky?
Observation Post #11, Mr. Grover said whales have been farther from
shore because of rough sea conditions. Comments like this remind us
that counting every whale is probably impossible. No one ever sees
all! Imagine and think as you tackle this week's journal question:
- What things
do you think affect how many whales are seen each day at each observation
as many variables as you can think of.

Whales: Finding Their Way

news of their return. How do they find their way on a journey
5,000 miles? It may not be so easy:
