The low pressure system that has been spinning up in the Gulf of Alaska has dipped down and brought southerly winds and a little rain with it.
These conditions are not conducive to migrants headed south and the rain cells obscure radar returns. And that is a perfect time to look at the Hydrometeor Classification filtered returns. In this mode we can see some biological activity, presumably avian, in last night’s loop. It’s very low level but noticeable. (brick red signal – “BI”)
Cackling Geese are now being reported, a few more Golden-crowned sparrows, increases in Sandhill Cranes and shorebirds are still on the move.
The radar was obscured by the weather last night. We could make out very low level movement between the cells but nothing to write about. I did hear a number of Swainson’s Thrush nocturnal flight calls the past couple of nights.
Up north in BC at the Tatlayoko banding station the first Fox and Golden-crowned Sparrows were banded and a flock of Greater White-fronted Geese were seen.
As DavidLaPuma would say, “look busy … birds are coming!”
Pretty much the same as yesterday – movement, but moderately so.
It’s always a good thing to keep up with what’s going on up north at the BC Tatlayoko Bird Observatory. They get a few birds that move over to the Central Flyway but many more that are headed our way. So, for instance, they will see the Fox and Golden-crowned Sparrows before we do and it is nice to know what’s in the pipeline.
