Early May has been a tough slog at the Farm….for two reasons: we got a downpour that dropped about 4 cm. of rain all over the area. This quickly ran into the low areas – the pond and adjacent wetlands – and the accumulation raised the water level by 10-12 cm effectively cutting off access to the river side nets and causing stakes holding nets to pull out in some cases. [I have subsequently replaced the stakes in wet patches with 20-inch pieces of rebar.] But the second, and main cause of the slow start, was that we were having serious trouble with our nets getting damaged. We had thought for awhile that this was due to deer running into them but it was happening consistently and in my experience deer don’t continue to bang into obstacles – they quickly learn to avoid or go around them. Also, the nets weren’t just being knocked down but the trammel lines were breaking. At least we thought they were breaking, but on closer examination it was clear that they were being cut. We’re pretty sure – well, 99% sure – that we know who is doing it – just don’t know what can be done about it. But it’s very aggravating and greatly reduced the net area that we were able to use (to say nothing of the cost of $150 US per net). Combine this with water level exclusions and you can see that we’ve been hampered. [This week we have worked hard to re-establish our net array and reinforce the staking system so they stay up – even when the levels rise.]
Despite these setbacks, we’ve been able to get some quality banding in and monitor the development of the migration – the influx of “new” birds is always exciting! And already we’re seeing new life that Spring brings: the pond’s Canada Goose pair hatched their 3 eggs just 2 days ago and a baby Painted Turtle showed up at the banding hut yesterday!
