This made us wonder…….just how many seeds are eaten every day?
And how much is it costing us to replenish the stock?
So, we decided to carry out a little experiment, the following is an approximation and figures are generally rounded up where applicable:-
Coal Tits observed in two 1-hour periods during the day, both AM and PM visiting the sunflower seed feeder giving the average as follows:-
Approx 225 seeds (weighing 15g – yep we weighed them!) were taken per hour x 8 hours = 1800 seeds per day.
Average 8 hour day x 15g = 120g of seed taken per day
120g per day x 365 days = 44kg of seed taken per year (approx)
A 3kg bag of seed costs €10 x 15 bags per year = €150 yearly cost
225 seeds = 15g
1kg contains approx 67 x 15g servings
225 seeds x 67 = 15,075 seeds per 1kg
15,075 x 44kg yearly consumption = 663,300 seeds per year
Only 10 birds (4 Coal Tits, 4 Blue Tits & 2 Great Tits) are currently visiting out sunflower seed feeder which equates to 66,330 seeds per bird per year!
Like I mentioned before these are approximations and obviously during winter the birds visit the feeder a lot more than summer months but then they would also have chicks to feed in the summer so I think it would probably average itself out.
Approx €150 spent per year just on sunflower seeds, not taking into account the peanuts, fat balls, fat squares, normal bird seed, meal worms, apples, raisins………..etc etc.
No wonder I’m always skint!
