It has been a very ‘sparrowey’ week at the Lesser Slave Lake Bird Observatory! Lots of sparrows of many species. Early in the week we experienced a couple days of rain that prevented us from opening the nets. Although we couldn’t band we were out as usual counting migrating birds. What we saw were thousands… Read more »

We are half way through September and it is looking like this is going to be one of the slowest fall banding seasons on record. I highly doubt we’ll set the record for the slowest (we are at around 1150 birds banded, needing only a dozen more birds to beat the worst year), but unless… Read more »

So far it is feeling like an average September, there is a steady trickle of migration on the non-windy days and banding is steady but not terribly busy. Myrtle warbler are still the most abundant migrant by a wide margin. Orange-crowned warblers are peaking as well as white-crowned sparrow and the slate-coloured junco and American… Read more »

It has been a nice little week; fairly sunny, warm and most importantly, calm. We’ve seen increased numbers of birds migrating overhead now that the air is still, including the first few flocks of Greater white-fronted geese. Banding has also improved with the calm weather and we are rapidly nearing the 1000 mark for this… Read more »

I feel like I have really talked about the wind a lot this year, but it’s hard not too when it is so constant. We’ve had another really slow week at the lab with reduced net-hours due to windy conditions. In the single calm day we banded just shy of forty birds of a good… Read more »

After what seems like an eternity of wind, the weather has settled itself and we have had a couple calm days at the Observatory. Wind negatively effects our operations in many ways, firstly, songbirds don’t like to migrate in the wind. They are very light in weight in comparison to their surface area so it… Read more »

Another slow week at the LSLBO. We have been hampered by windy weather that forced us to keep our nets closed more often than not. We only recently cracked the 600 mark for the fall; typically we are around 900 by this time. The slow banding coupled with the lack of overhead migration is furthering… Read more »

Over the past week, migration has slowly picked up. We are seeing Tennessee warbler and myrtle warbler moving overhead in increasing numbers every morning. Still nothing like we expect to see this time of year, but it’s an improvement from last week. Other species that are steadily migrating are western tanager (in surprisingly good numbers)… Read more »

Bird activity is still slow at the observatory, slow enough that we are starting to wonder if something is wrong. We spend our many hours of not seeing or catching birds speculating as to why we have so many hours to spend speculating. We have one main hypothesis that has a couple pieces of supporting… Read more »

Unfortunately it has been another slow week at the Lesser Slave Lake Bird Observatory. Not many birds have been seen actively migrating and even fewer have been banded. We partly blame the poor weather again, but even the nicer days haven’t produced much bird activity. Despite low levels of migration, there are still lot of… Read more »
