Quite interesting Carol.

Just over my place in Seven Hills, I usually see on average about 200
White-naped or Yellow-faced Honeyeaters per hour, but this year I have not
seen either!!! The only migrating birds I have seen/heard in my area this
season are Silvereyes. I have not heard/seen any Striated Pardalotes yet
this season, but they can be quite common in the area (ie) the Tasmanian
(yellow-tipped) race. This year however has been very exceptional for the
Musk Lorikeets in Seven Hills with upto about 50 seen from mid February
right till today. I have been watching them feed on a Spotted Gum with many
Rainbow Lorikeets, Red Wattlebirds and Noisy Miners every morning while I
wait for the bus. The same tree last year had many Yellow-faced and
White-naped Honeyeaters feeding with Rainbow Lorikeets, Red Wattlebirds and
Noisy Miners and several Striated Pardalotes nearby.

>Since then, on most fine mornings I?ve had between 1000 and 2000
honeyeaters per hour flying over my street. That?s not much compared to
most other
years - really!
>As to the composition of the flocks, the first White-naped started
appearing on the 12th April. On the 20th, Yellow-faced were still approx 92% of
birds, White-naped 4%, Spotted Pardalotes 3%, with smaller numbers of Striated

>Another interesting thing this year has been the large number of pardalotes

>All this brings me to some questions. Have people in other areas (e.g.

To add to the above, what was unusual this year (to me at any rate) in the
Capertee Valley during 2 visits in May, was the really large numbers of
Spotted Pardelotes and Yellow-tufted Honeyeaters, along with normally large
numbers of Fuscous and White-plumed HEs, and reasonable numbers  of
White-naped HEs.
